Now that the weather is cooling off, we have a little more time to sit at home and… rest. There hasn’t been much of that in the last 6 months! We applied a coating of low-VOC oil-based sealant to the siding after pressure-washing it to remove some of last winter’s water stains, and caulked like crazy as the washing removed some of it. We also decided that although we absolutely love the look of wood, the cedar-faced plywood wasn’t that attractive, and could use the protection of paint against the rain. We chose a low/zero (can’t remember – the least toxic exterior-grade paint available at the big-box store. It was by Behr) paint, and we think it really adds to the look of the house:
Next up, seal the horizontal band and the window/door trim. Also thinking of installing a removable awning over the French doors.
After the massive, 5x-record-breaking rains we had in September that showed us where all the leaks were, the house has been thoroughly caulked and weatherproofed. Oddly I discovered that we haven’t taken any pictures yet of the finished siding on the long wall, so we’ll post that soonish. We both really like the window frame style we chose, even though it is one more reason our house will not have a unified style. The French doors have proved to be the most challenging of the wall openings we have in terms of waterproofing, so beware if you choose to add them to your house! May be one of the reasons why many tiny houses with French doors have a porch covering them…
We did put up the lap siding, board and batten on the front door side, along with a small drip edge, although nothing is stained yet, so it is various shades of cedar. The white areas will soon be covered with cedar shingles, which will be gorgeous when done!
We also made good progress on the 12 v system, which is important in order to have the water pump up and running. Part of that included the biggest dang breaker I’ve ever seen, for 275 amps (!) DC:
That breaker weighs several pounds. We procured it to protect the inverter/charger from excessive 12v input, whether from the batteries, solar panels, wind turbines, or generators. We also made a breaker cabinet for the 12 and 120 v breakers feeding the inverter/charger for easy access from the outside:
And made a bunch of custom cables to run between the batteries, breakers, and inverter/charger. Got a lot of raised eyebrows at a Big Box store when I asked for 2/0 wire. (Guy looks at chick, thinks she’s confused, and says, “You mean, like 12 or 14 gauge wire with 2 wires? Like, you know, the kind in your house?” Sees my face, then asks, hesitatingly, “Or you mean, really big wire?” Similarly, the lady at checkout asked me no less than three times what I was using the wire for, but first asked me if I bought it there. That wire weighed a lot and made about a 30″ dia loop when coiled, so you guess how likely it would be that I brought it from home. When I told her it was for a 12v system, she looked even more befuddled). Bought their last 15 feet of the stuff, and proceeded to find that they do not carry terminals in 2/0 size, only #2 size. Auto shops are not helpful, as they carry #2, at the largest, of both wire and terminals, in my experience. Ace Hardware to the rescue! They carry an array of all-copper, 2/0 ring terminals, for a cheaper price than buying off Amazon. Man I love those guys. We could have bought even bigger terminals, or in different styles if we wanted, because they’re that cool, and carry it all. Then to attach said terminals to the cables. For this, there are many professional-grade, hydraulic-assisted lug crimpers out there, and they cost a few hundred dollars. Harbor Freight sells one with individual dies for the differing gauges for $80, online only. My dad told me about this mysterious metal block thingy with a plunger on it that you hit with a hammer, and after much hunting, found a single specimen at a big-box auto shop. It truly is just a heavy pin in a jig that you use to smash the lug with when you hit it with a hammer, called an “auto lug crimper.” Works great though, and cost $21. Ended up saving quite a bit of $$ making the cables ourselves, not to mention 2/0 cable is not too flexible, so you want exact lengths anyway. It’s stupid the things you view as triumphs, but we were pretty proud of that.
Successfully tested the gas lines, which held pressure beautifully after 5 min of final tightening. Used a little gauge from the Big Box store on a plumbing tee with a bicycle pump fitting on one end. A beautiful sight after several hours:
Also installed the last stained-glass window, over the kitchen sink. Like the other one, it is an antique from an English pub. We thought the goblet design was appropriate for the kitchen, set into a custom-made new cherry wood frame, with room left to install a second plate of glass on the outside to protect it and insulate better.
And we talked to Monty, and he mentioned a few things that we will have to do before he *might* be able to pass us on inspection of the house for a homemade “park trailer” – vents are required on the sinks and tub, which he said can be “auto vents” which vent via a tee just past the P-trap to a side wall, and are one-way vents. They look pretty inexpensive and easy to install, so we will probably try to do that. He also said a 30amp main breaker in the breaker panel is necessary, which I was thinking was a good idea anyway. And lastly, besides the smoke, CO, and LP/gas alarms which we already have, a “5BC” rated fire extinguisher, mounted near the front door, in a clearly visible place, is required. So maybe there is hope yet that we can have our house certified as a park trailer. We’ll keep you posted.
Overall, we have not once felt that our house was too small for our needs, though. Which is funny, because that seems to be everyone’s concern. Our difficulties currently lie in working full time while completing our house, when neither of us are a plumber, electrician, sider or roofer. Perhaps it will be different once we have more built-in furniture, but we don’t think so. We’ll just be happy to be living less like transients.
And if you are fecophobic or otherwise squeamish, do not read this last portion. For those who are not, and/or are contemplating a composting toilet system, read on:
We have gone through several phases of toilet-care philosophy. Much like Cat, featured on The Tiny House Blog recently here, we have decided that much of the toilet hype is just that. Phase 1 was the Humanure Handbook philosophy, which goes something like: “Put it all in one bucket, cover with several inches of dry sawdust or similar, and then throw into a massive compost pile when the bucket is full.” Except since we are on a small, narrow lot, there is nearly nowhere to place a compost pile that wouldn’t be too close to a neighbor’s yard, so we were going to garbage-bag it into the trash. Problem was that unless you covered every single time (regardless of #1 or #2) with a large amount of mulch, it stunk, bad. If you did, the bucket filled up within a few days, and let’s face it, no one wants to be the one to change the bucket out, or deal with a really massive compost pile if you don’t have lots of property.
Separation of #1 and #2, cover #2 with mulch, hang a separate cup in the front of the bucket for #1. Worked really well to decrease changeover of the bucket. Discovered that humans make a tremendous amount of urine daily, and that almost all of the bad smell from the toilet was from the urine, not #2. So instead, now we are emptying the pee pot daily, in loo of the bucket weekly (haha, get it? moving on…). Not a huge amount better, but slightly. If you slack off, there is, as the Scandinavians delicately put it, “A sulfurous odor associated with outhouses.” Not terribly nasty, but not really nice, either. So, we thought, there is a reason all those fancy expensive toilets (Airhead, Nature’s Head, etc) have urine separation and a closed urine collection system! Whaddya know? But, as Cat pointed out, those guys are spendy, and not the greatest. Some people we know with a tiny house have a Nature’s Head, and they said the urine bottle fills up almost daily, so aside from an improvement in smell, maintenance levels are the same.
Should have happened a long time ago. Looked high and low for a reasonably-priced urine separation/diversion setup. EcoVita.net has the best selection of the main brands we have found in the US. Separett (Swedish company, of course) seems to make all of the low-end, basic urine diverting setups, but the cheapest ones are hideous, and $120 if you include shipping. A lot for a bit of plastic, but I guess that’s because of importation costs since the US can’t seem to get their you-know-what together, pardon the pun. They can market them in the US as “emergency toilets” and thereby get around all of the stupid laws that abound regarding home toilet composting. Interestingly, in continental Europe Separett markets a model called “Dass Isak” which is a holdover model from their former competitor Isak. Although mostly made of styrofoam, it has a fitted lid, an attractive shape, and a one-piece urine diverting seat out of white plastic, instead of bright blue. It is even cheaper than the “Privy Kit” but Separett politely informed me that it is being phased out and is not exported to the US. The only company that was willing to export it seemed to charge a “stupid American tax” of around $40, plus shipping, which came to around $200. Sadly not worth it. What we opted for was available on Ebay for $50, and is a basic black plastic funnel that flares out so you can nail/attach it to the underside of your toilet housing, and has a neck that fits a standard-sized hose. It seems to be made by a company out of the UK. Ours will arrive later this month, and we are inordinately excited about it. We are seriously thinking about running said hose to the tub drain just past the P-trap, and never having to empty any urine container, inside or out, ever again. It seems that everybody eventually arrives at the conclusion of running the urine directly to a drainage bed, or to a large holding vessel outside, that is then emptied periodically. Urine doesn’t stink until it’s sat for a bit, so much like grey water, I suspect storage, for any length of time, is not a good idea. Here is the big fuss:
Many Scandinavian webpages recommend “washing down” the urine with a small amount of water, to dilute it so it doesn’t burn any plants in your drain field and also to prevent crystal buildup. We think that is folk wisdom to be followed. Incidentally, the Scandinavians seem to be really passionate about their outhouses (just look up “Torrdass”), their history, styles, and construction, so they seem to know what’s going on better than most. I’ve read that bamboo is especially tolerant of high nitrogen and salts, so not sure if it’s better to make a native rain garden to drain our mixed waste water to along with excess rain runoff, or have a separate mulched and planted area for it. Ideas on that front are welcome!
We have been told we are too long in updating our progress, and this is true, but not out of negligence, dear reader. In large part, today’s post is made possible by the recent completion of a store with wifi near our house, as our host’s internet proved inadequate to reach us (soon to be amended). This was compounded by the abrupt and complete death of the Mrs’ laptop battery upon moving to the tiny, rendering successful Internet access even more difficult. Funny on hindsight, not so funny at the time!
Moving was a painful process. As always, we were disgusted by how much stuff we had, but this time, we had to find new homes for so much of it, and organize it according to “we are using,” “we will be using,” “we need to re-home,” “we need to recycle,” and “we need to store.” We do not like to throw things away, because the landfill has enough in it already. Organizing as we packed and moved proved logistically complicated. As it turns out, Americans on Craigslist like to look the gift-horse in the teeth. We gave away a lot of our very usable stuff for free, only asking that the new owners pick it up themselves (with our help), and yet it took a great deal of effort just to make that happen. We were amazed at how well people have been trained as consumers that they don’t even want free things unless they are in pristine condition or they are gouging the other person. There is no “fair price,” only “I win, you lose.” We did find some good homes for things, eventually, but it took a lot longer than we expected.
We are also happy to report that we are bibliophiles in reform. We have finally come to the realization that you can have too many books, and we both do. We took many boxes to Powell’s, as you can see by the truck bed full of books to sell/donate. A tear or two might have been shed. We won’t tell.
Progress has been in the form of installing the metal flashing on the lip of the floor on the long sides of the house, to accommodate siding “hips”, in part because apparently pouring rain was the plan for late August, and it pools terrifically. Also flashing for the edges of the roof, so that the metal sheeting can finally be installed over it. No interesting pictures of these additions, because flashing is pretty boring and straightforward to install, and not much to look at. But believe you us, DRY IN your house before you insulate and panel if you possibly can. There is a reason it is always recommended in that order.
Second area of progress was the successful installation of the gas lines to the water heater and the stove. Although the name implies flexibility, CSST is indeed not very flexible. It is about as easy as routing a garden hose through a wall. The holes are almost as large, and the exterior coating over the corrugation provides an awful lot of drag. It took two people to route the gas lines through 15′ of wall, working really, really hard to yard that stuff through. And although we bought 1/2″ tubing, the actual outer diameter is at least 3/4″, so all the holes had to be drilled to 7/8″ to allow ease. On hindsight, we would recommend running your plumbing and gas lines before electrical, for this reason. The upside to the CSST is that the connections are very secure and easy to do well. As soon as possible, we will be installing the propane tank shelf in the closet and buying a very, very safe NEW multi-stage regulator. (We have heard horror stories firsthand of regulators failing and subsequent massive explosions.) We will be diligently pressure-checking the system before closing up the walls and going “live” with the propane.
We have been slowly installing lights in the house, although some must wait until the sawdust has settled or they will be immediately gross. We did install the bathroom vanity lights, which we really like. Our little medicine cabinet and sink will sit just under these.
And the crowning glory of the bathroom – a bonified, non-stinky, non-tippy, pretty commode! In terms of Maslow’s hierarchy of needs, I think having a secure, easy-to-use toilet spot is pretty much up there with water and food and sleeping space. Take heed.
And we finally tackled the rat’s nest known as the kitchen sink area, as it contains hot & cold water lines, the water heater, the water heater exhaust, the gas lines, and the supply lines for the water heater. All in a teeny tiny space that can’t be an inch larger than allotted for. I think we posted a picture of the sink before, but it stands to be repeated. An area of real pride for us!
In preparation for insulating and siding the interior, we insulated and boxed-in the wheel wells, using leftover Reflectix in immediate contact with the wells so that no evil water condensation is likely to happen.
And this was probably not immediately necessary, but the Mrs’ plants were languishing in the alternate scorching heat and pouring rain, with nowhere to go, so the bay window shelf was completed for the plants to have safe shelter.
Sorry we have been so long in updating our blog regarding our progress. As is usually the case, when things get really juicy, it’s when one is super busy. And such was the case with us. (We move in on Thursday!) We have been lucky to have friends come help, and the local sandwich shop guy asks every day at lunch how progress goes (he loves Lloyd Kahn, too!) And yes, we will be camping out. We have electricity*, a roof overhead, and a place to sleep, but that is where it ends, for now. But it can’t be that bad, as we are choosing to move in instead of paying for another two weeks of our current rent, which is an option. Or we’re pleasantly nuts, which is also possible. This is the theory some of our family has taken up.
The progress is as follows:
Reflectix installed between the rafters. That stuff is amazing. We ordered it figuring it would be a good idea given our current roofing is black underlayment, soon to be followed by aluminum sheeting, neither of which is known for good thermal cooling properties. Now we wish we had used it for the entire envelope prior to sheep’s wool insulation. Reflectix is similar to what lines your lunch bag – it has excellent radiant heat/cold insulation properties, advertised as 97% efficient. We can tell you, just by stapling that stuff up, without even the insulation to go over it yet, the indoor temperature was close to 10 degrees (F) cooler at lunchtime compared to our confused/sweaty/grumpy prior afternoons.
Next improvement was more paneling, and the installation of the shelf for the fridge and start of the closet underneath.
And more paneling in the loft area so we have a place to put our clothes and bed in a few days.
Also, electricity works in all circuits*. As mentioned previously, we have 4 circuits, (2) 15 amp and (2) 20 amp circuits. One of the 15 amp circuits, much to our chagrin, kept tripping the breaker when we fired ‘er up. Turned out to be a cable clamp that had been over-tightened, short-circuiting the wire. Also had a faulty GFCI circuit, new from the Big Box Store. As we closed up tonight, we realized that the kitchen circuit did not shut off when the breaker was switched, which was not cool. *We have since found that the breaker was fine; mislabeling and tired brains were at fault.The gas lines, similarly, have been a bit of a pain, which, when time allows, we will provide our reflections on.
Last but not least, the beautiful Dutch door is nearly installed. We love the rounded top, to match our rounded roof. And the hardware is all ready to go, same for the French doors.
And although the bathroom is not usable yet (take that back – the bucket has been, ahem, christened), we did put up a little curtain for privacy from the street while still having a little air flow while working. It stood as a foretaste of what our little house will be, so very soon. It will be a future full of house plants. It’s a cheery, domestic view.
Next time we post, we’ll be living & camping in our beautiful house! What better way to learn what you really need in life?
This weekend will seem rather boring on virtual paper, as it was mostly logistic, and we have a pathetic number of pictures as the usual photographer was busy doing the work mostly alone. But fear not, that won’t stop us from boring you with the details! You want the authentic experience, right?
Drilling nice, perpendicular, centered holes in studs that are closer together than 16″ o.c. is difficult, so the installation of the plumbing was stymied by a seemingly minor detail. A right-angled drill would make the job magnitudes easier, but we couldn’t seem to locate one, oddly. Even the Craigslisters who advertised ones for sale didn’t call back. We are hoping the NEPTL will help. Tool libraries are the cat’s pyjamas, so you should see if there’s one in your area.
We did install most of the 12v wiring since those holes are smaller and if they are less straight, no one cares. And we picked up our interior paneling, some very attractive 5/16″ thick by 4″ wide tongue and groove fir. Again, it was salvage and in mostly short sections, but looked like clear, close vertical grain, suggesting old growth (without the guilt). Also, a friend of the family has offered to give us all of her pine trim from her house build that she didn’t use, for free. So supplies are coming together. Happy day!
One of us, who shall remain unnamed, was having a bit of a heart attack over the weight limit of 10,000 lbs, as we are currently sitting at a little under 7,000 less tools and extras. So, after some serious panicking, we learned the difference between linear feet (lf) and board feet (bf) when calculating lumber weights. They are not the same thing. Linear feet is what you’d first think of – the actual length of lumber, but it is difficult to calculate weight as widths and thicknesses vary. Board feet is an assumed 12″ wide by 1″ thick piece of the wood you are choosing, even if the boards you are buying are not 12″ wide by 1″ thick. So board feet is the more helpful but confusing number, as it is a volume of wood rather than a length when calculating the weight of piles of lumber. But bf was exactly what we needed when deciding on our future lumber choices for siding and paneling. Board feet is used most commonly for hardwoods (as opposed to the softwoods most often used for framing), and is calculated either as width (in inches) x length (in feet) x thickness (in inches) x 12, or as width x length x thickness (in inches) / 144. Then you can figure out the weight, for a given moisture content (wetness) of the wood, based on standard values for 1000 bf, which you can find in tables all over the internet. We realized we will be heavy, but not catastrophically so as originally miscalculated! Hence finding 5/16″ paneling, instead of using the ubiquitous 3/4″ thick pine tongue and groove. Fir is slightly heavier than pine, but when you are looking at something less than half as thick, it will be much lighter. And we did install a small wall’s worth of paneling, just to get the hang of it and feel like the weekend wasn’t a wash:
The wood will need to be sanded, but we kind of liked the “rainbow” effect. And we fluffed and filled with wool insulation as we went. Very gratifying.
Also, the weather portends rain in a few days, so we were very excited to have our Grace Ultra underlayment arrive. It was the least toxic waterproofing roof underlayment we could find, to go underneath our aluminum sheeting, so it had to be high temperature rated. Instead of being made from asphalt rubber or plain tar paper (all nasty fossil fuel based things that reek) like most, it is made from butyl rubber over a sheet of essentially Tyvek. Still fakey, but hopefully not as bad. We also ordered Reflectix, which is glorified bubble wrap with a metallic foil coating on it, to block radiant heat from the roof, as that seems to be the main source of the heat coming into the house. It has an efficiency rating of around 97%, which seems like a darn good number. So that will be installed just inside the roof sheathing, followed by wool and then paneling. Should be nice and cozy.
Last thing is the thorn in our side: the propane system. In addition to the abovementioned hole drilling problem, there are other obstacles. This one, it seems, the “Experts” have cornered the market on. As we see it, there are three main choices for running gas lines in a tiny house: black pipe, which is heavy, stiff, and a real pain to install, flexible copper pipe which requires careful installation and specific fittings to be airtight and has a much smaller diameter (at least all that we could find), and CSST (corrugated stainless steel tubing), which I have mentioned before. All brands of CSST have proprietary, non-interchangeable fittings. You can buy the first two types of gas lines at Big Box stores (the copper pipe can be found in the “icemaker” section, near the fridge stuff), and you can buy one type of CSST online from a certain Big Box store, namely AlphaFlex, which is the same thing as Homeflex. However, AlphaFlex/HomeFlex are made with PVC. There are other brands, such as ProFlex and TruFlex (I don’t know if they are affiliated with each other) which use less toxic plastic coatings, and their fittings also include a rubber gasket, which seems like a really good idea. However, all of the above types of CSST and fittings cannot be found in a brick and mortar retail store in this town. In fact, if you call any place that advertises that they stock gas line stuff, they get really huffy when you inform them that you are “doing it yourself” and tell you how you couldn’t possibly know what you need and should have an Expert determine that for you. Puckey, I say. So we ordered on Amazon. Even ordered the how-to booklet for installers who want to get “certified,” and it doesn’t look like a very long read! We’ll let you know how it works out. So far, the lesson learned is: do not be optimistic in your lengths of line. Patchwork propane lines are frowned upon, obviously. The good news on the propane front is that we have a sympathetic uncle who knows how to pressurize the system as required to check for leaks, and has all the fittings to do so! So don’t worry, we won’t be endangering anyone with our propane system, sans Experts.
This week, we hope to install the Grace Ultra in time for rain, and continue paneling and insulating as we finish installing the necessary pipes. May even wire up the switches and receptacles, so the house can be “plugged in” and have actual lights on!
This was one heckuva weekend, with mad buttoning-up of things for travel on Sunday. The doors had been neglected until now as they require extra attention (such as custom door jambs) to install; the French doors were originally fixed glazed doors, and about 18″ too tall for the under-loft area, so they had to be carefully cut down, glued, and clamped, and a jamb made. The bottom sill of the French door jamb was made from scrap white oak, with a carefully-cut slope to it so that all water would drain (you can’t buy 4′ wide sections of metal threshold/sill material at the Big Box Store). It’s one of those niceties we will appreciate although it might not be obvious to the casual observer.
The 12v DC wiring did not have a functioning breaker panel to connect to, so the Ebay boat panels were torn apart, sanded clean (’cause they’re old and made of metal, not cheap plastic), and re-assembled with the proper breaker sizes (primarily 5-10 amp). We made a little housing for it so that the rear of the panel can be accessed for maintenance. The breaker switches are also the on/off switches in this case, which works fine. We think it looks steampunk, which is always good!
And in the process, gained great respect for Ace Hardware over other Big Box Stores – we always liked that store over the Big Box, and learned that particular bias from our respective dads. Coincidentally, it seems the place is staffed with DIY dads. Well, another reason why I love them: I called the plumbing and electrical specialty store in town, and after passing me around, found one guy who “kinda” knew 12v – by which he meant, he could discuss LED lighting with you, and recommended I visit the auto electric shop in town to get advice for real 12 volt stuff. I view that as good customer service, nonetheless. But I went to Ace first, just in case, found a great selection of wire for my needs (10-16 AWG, or American Wire Gauge, wire), and the first guy that walked by I posed the same question to: “Do you know anything about 12 volt?” and he answered, “I know all about 12 volt,” as he pulled wire. This surprised me. I asked why, and he said he had previously wired RVs for a living! At this point I freaked out and asked him all the questions I could, since he was the first person I met who knew anything! Here are the highlights:
1. What is the recommended treatment for wire junctions/terminations (i.e. electrical boxes)? Answer: none. You can end the wires in the middle of the wall, just put a couple wire nuts on the bare ends, no box needed.
2. Does it matter if you use larger gauge wire than required for the load or distance? Answer: nope, only a problem with smaller gauge wire than required. It’s just a little more expensive.
3. Where is the best place to get 12v wiring? Answer: auto supply stores often sell rolls of 14, 16, and 18 gauge wire by the 25-50′ for cheaper than by-the-foot wiring. The larger or smaller stuff, get here.
4. Does the color matter for positive and negative? Nope, whatever colors you want. Many people use red and black, but any color will do. Just stick with the same colors so you don’t get confused.
5. Why doesn’t everyone use 12v systems when they are so cool and easy to use?? Answer: The power source has to be close due to losses over distance. Otherwise, no good reason. If you get shocked, “It’s not even bee-sting material.” Fire hazard is low. My note: You do, however, need to use 12v – approved switches rather than regular 120v switches due to the larger amperages, as they can actually melt the terminals of a regular switch if they arc. RV and marine stores sell 12v rocker switches, and the plain ol’ metal toggle switches seem to be used with no problems, either.
So I was stoked. If we ever do anything with the Palomino chassis, I’m doing all 12v DC, just for the fun of it. And maybe I can get my sister involved, too, as it seems 12v DC systems are a great introduction to electrical systems. Would have made my high school physics class WAY more interesting…
And we also installed the 120v, 30 amp RV electrical inlet and water inlet, in the newly lined utility closets (for vapor and spark protection). Since we are poor and don’t have our power center or inverter/charger for self-made power yet, but want to be able to plug-and-play later with solar, wind turbines, or generator, we put two gratuitous junction boxes in the utility closet and ran extra conduit through them, so that it will be easy to add those components later without having to try to run more conduit and have a messy cabinet. Messy electrical closets are ugly and bother me.
Word to the wise: you’d think there’s only one kind of 30 amp RV AC inlet. Wrong. There are two kinds – both have three prongs, but one is a regular plug and the other is a twist-lock variety. Both work, but they are not interchangeable, although they make adapters. The twist-lock variety seems a little more secure, so many of the new 30 amp RV cords have a female locking end and a male non-locking end, like this. Make sure you know what you are getting. I didn’t, and was surprised when I opened the inlet after getting it in the mail. Also, when I talked to Monty Taylor regarding “separable” vs “non-separable” power supply for RV inspection, he said he doesn’t care so long as it’s done well. However, I didn’t think about male vs female receptacles/terminals when I bought one the first go-round. I got a 30a regular 3 prong receptacle (female) for the house. Well, that doesn’t work. You need the plug (male) end installed in the house, so that when you hook up a cable, the male end is free to plug into your power source receptacle and the female end plugs into your house. Can’t have a cord with two male ends, can we? Duh. Good news: if you’re like me and you’re cheap, and you saved the cord from the pop-up camper you ripped apart (those power cords are $50 and up man!) that was permanently attached so one end is a stub with raw wires sticking out, you can buy male and female adapter heads online and at any RV store for less than $20. So that is what I did. I bought an adapter for my twist-lock 30 amp inlet to that we can use either type of plug, and bought a $17 female adapter head with standard RV 30 amp layout to attach to my raw cord. Clear as mud? Yeah, me too. Result is, we are ready for any type of 30 amp power supply! Mwaha!
Next, the utility closet got its cover and doors, and all the window and door openings were covered with plywood for the drive. Hurricane clips were attached from rafters to top plates to secure the roof, and we also added some straps to the front eave, for upward forces while driving.
For the moving day, procure yourself a heavy-duty truck to do the pulling, and a good, optimistic friend or family member to drive behind you and call periodically to tell you nothing has fallen off. And as Dee Williams says in her e-book, to also tell you, “It’s so cu-ute!” and soothe your nerves. In our case, have the calm ones in the big truck, and the documenters following behind (only if not driving, of course) and providing caravan-afforded protection from tailgaters and other silly people.
For those who look at our house and say “It’s so tall! Are you sure the wind won’t blow it over?” the answer is that it did great on the road. We had no concerns driving it whatsoever, and in fact it surprised all of us, in a very welcome way. The only thing that wobbled was the license plate, because it’s attached by a flimsy plastic bracket on the top only, which we can handle. Nothing flew off, nothing was broken. Sigh.
We do recommend using a truck weigh station to find out how much your trailer weighs, while you’re on the road anyway. You don’t have to pay, it isn’t hard, and the scales are always on, even if the station is closed. We found out, after much panicked calculations, that our house weighs about 800 more than we had projected, at 7,300 lbs. For those contemplating a rounded roof such as ours, do keep in mind that you will have considerably more wall height, and therefore weight, compared to a typical Tumbleweed gabled house. We did not consider that in our calculations. Oops. We are now left with less weight to work with in finishing, but with care we will still come in under our weight limit. If you look up Colin’s Coastal Cabin on The Tiny House Blog, he has a shed roof but similar high walls, and he came in at 9,000 lbs. His house is gorgeous and well-made. So be aware of weight! It adds up in a sneaky sort of way.
Now, getting our tiny house onto our narrow lot from our narrow lane with a large truck and rented power mover, that was a long story, to be discussed at a later date. The happy ending is: our house is now resting comfortably on our lot, with jacks to stabilize, and many neighbors already stopping by to ask questions, only 10 minutes away now instead of hours. About three weeks left until we move in!
This weekend was the Mr. and Dad working solo for three days. They did so much beautiful work! They finished the infernal staircase, and the storage loft, made some significant progress on the fiddly-angled-but-important utility cabinet on the tongue and installed all kinds of windows. The addition of the windows really makes it feel like a house! There were also a few snafoos, with the water heater (an Eccotemp 2.6 gpm outdoor LP tankless) not being the dimensions listed on the website (on Amazon or their own website!) … and since inches matter, the cabinet we had built for it was now a few inches too small! So we will have to figure something else out. Eccotemp seems like the best brand at this time in terms of price and size. The two ideas are: to sell/return the one we have, and get the inside version for a little more, and keep it between the kitchen sink and shower, which in the end might be more efficient, or do a funky custom cabinet and install it where we were planning. So perhaps we will make lemonade after all. Also, the matching casement windows for the upstairs are actually made from a two-part window which we split – and we found out that the flange we really need to be intact (on the top) is exactly the one that isn’t. Hmm. Annoying, but not the end of the world. Here is our gorgeous house in pictures!
The stairs were designed so that the top step is really steep – so when you climb into the loft, you won’t hit your shins, and you have a place to sit and put on/take off shoes. The thick steps are reclaimed fir, the runners of cedar. All the Mr’s great ideas!
The utility closet is lined with Magnum Board (magnesium oxide board, similar to cement board but better) to prevent sparks from the batteries from getting to the propane tanks, and to insulate and waterproof the spaces. The plan is to keep the electrical on the left side, and the propane and water on the right. See the lovely angles of the corner cabinets? They will hopefully help make the front of the house more aerodynamic than a barn when towing. Our wooden faceted diamond.
We bought two antique English pub windows (about 100 years old) of stained glass. However, the frames were falling apart and covered in peeling lead paint. So we carefully removed them from the frames, and the Mr. built this custom frame out of some cherry wood scrap. He really did a professional job. And it dominates the bathroom in a wonderful way that we did not anticipate.
And the window I call the “pretty window” is installed over the kitchen counter. We bought it from a very nice man who remodeled his turn-of-the-century Craftsman. It still has all the original hardware, in perfect condition.
Since we are in crunch time, work will re-commence within a few days, and the Big Move will be happening by the end of the week if all goes as we want it to!
This was a marathon weekend. Closer to a week of work, actually. We started on the 4th by cutting the 2×12’s for our couch back/bookcase/bathroom wall and installing the pocket door. Which was really cool, ’cause then we could really have a feel for the bathroom size (tiny – haha). By the way, if you decide to put your bathroom door at the end instead of the middle of the bathroom, I cannot tell you how much of a difference it made to make our bathroom 3’4″ wide instead of 3′. Seriously. Happily no one got a picture of me making the discovery by “trying out” the bathroom with a 5 gallon bucket and our wooden toilet seat, but it was suuuper tiny. Add four inches, and all of a sudden it’s pleasantly cozy. But I suppose that “inches matter” should really be the tiny-house-planning and building mantra. If you bought Tumbleweed plans, then you can grin your smug little smile and pooh to my mantra. But for those like us: your happy little pencil sketches get stretched and squeezed like you wouldn’t believe with the addition of a single 2×4, and all of a sudden it is a crisis figuring out how to allow for the window trim. That’s character and wisdom gained, right there.
But I digress. We noticed that everyone puts the toilet on one side of the door and the shower/tub on the other, using a doorway in the middle as the bathroom floor space, and then they put the kitchen under the loft next to it, so that both are claustrophobia-inducing, but very space-efficient and share the same sink. But we didn’t like the idea that efficiency is the highest good, and bathroom sinks can be really small, if you even want one. We both love Alexander’s A Pattern Language, and decided that the archaic “we have servants do all our cooking, so let’s put out kitchen in the closet” idea is stupid. So we put our space where we spend our time (in the kitchen, as for most people), and made the under-loft our “intimate” space, such as seating. We also designed our house so that the farther into it from the front door you get, the more private the space, which is also comforting and intuitive. Those two things were made possible by running the bathroom along the back, which, unlike the kitchen, makes sense to put in a closet. Plan is to make the front face of the pocket door a slightly shallower continuation of the bookcase (paperback novels, anyone?!), which also serves as the bathroom wall. We’ll put tongue and groove and/or Magnum board on the bathroom face of the bookcase, and the couch will sit in front of that, with bulk storage cabinets in the seat and the couch back, and faces out. We have some nice French doors under the loft which, later on, will be continuous with the patio and the couch area.
Next up was shaping and cutting the loft joists out of 2×6 cedar-with-character as the father-in-law puts it, which required careful planning of what to cut and which joist went where, with what face. But we all agree that the careful planning of the joists really adds flair and craftsmanship to the design. I think it makes the house look Cascadian, or Scandijapanavian, our favorite styles 🙂
We also had the brainwave that we could skip placing a joist over the middle of the shower stall, and just use a block across, since it only has to span 3′. That gave us a lot more headroom in the shower, which is great. Might be a good spot to showcase our large piece of copper sheet. Downside it that the small, efficient, low-noise exhaust fan/light that I was going to install between the joists now has no good place to go, because all of them are designed to fit in a 6″ deep wall, unless they are the cheesy RV variety. It will probably have its own box made in the upper corner near the water heater, and the exhaust will just have to take a slightly more circuitous route to escape. No spilt milk.
Then we laid the loft boards, which I am in love with. They are short cuts of close, vertical-grain fir 1×6; leftovers from someone else’s project, and perfect for our purposes. We used the nail gun for a nice clean look. And as soon as it was done, day 2 was over with. Some teenagers immediately claimed the loft, located a mattress, and camped out for the night.
A party with passels of cousins, munchkins, and rainbows galore followed, so Saturday was a wash. Then there was the staircase. Sigh. Complicated, as it turns out, by the fact that we wanted a staircase instead of a ladder, with a wood stove underneath. Because staircases are usually well-supported at the top by a vertical wall or a heavy-duty set of joists, neither of which we are willing to concede. So it will be suspended from the ceiling, we think. Structural finish work, as the carpenters call it, can be fiddly business. So the stairs are TBD…
The other big victory was the placement of all the 120v AC circuitry in the house, made possible by another awesome dad and several trips to the Big Box of Chemicals & Sundries. That is, all the AC stuff is “stubbed in”, which means that the boxes and the wires are run, but the receptacles (outlets) and switches are not placed yet. But comparatively, that part just takes some logic and a morning of work (or so I say haha). The location of the AC panel was something of a conundrum, mostly due to lack of knowledge – in the dim hope we can get the house certified as an RV, we weren’t sure if the AC panel had to be placed within a certain distance of the power entry to the house (for boats it is within 7 or 8′, we hear), and we also did not want an electrical panel, humming with electricity in a stupidly-designed EMF-generating electrical panel, sited under our sleeping heads. For the latter, I still don’t know, because even though we bought a centered-load panel, the breakers don’t all sit immediately adjacent to the neutral bus bar. Grr. I hate being superstitious about that kind of stuff. But alas. The former requirement, I am happy to report, we do not have to worry about, as I’ll mention below.
We found out that the guy in Oregon to talk to about RV certification of a tiny house (which can, and has been done) is named Monty Taylor, the RV inspector of the Building Codes Division, and he travels all around the state. He can inspect a tiny house, and if it meets all the codes of a “park trailer” he can certify it as a homemade RV. Why would we care, you ask, since we hate permits and bureaucratic governmental interference and infernal fees? Because a recognized RV can be insured. Otherwise insurance companies view us and our houses as a hazard to their profitability. We aren’t super set on getting the house permitted, but if what is required and what we want to do are reasonably similar, then why not?
Here’s the juicy bits Monty told me, which for some reason I haven’t seen listed anywhere before (and Monty is a nice guy, so if you want to hear it straight from the horse’s mouth, call him on his cell, the number of which he lists on his office voicemail.) This is what he said: there are no structural requirements for a tiny house. For the electrical, you need Article 552 (on Park Trailers) of the National Electric Code (NEC), which can be found in the reference sections of most public libraries, and it’s only a few pages long, so just photocopy it so you can read the legalese at your own leisure. It wasn’t bad, and most of the stuff is really intuitive, like don’t have an electrical outlet within reach of the tub. Duh. For the rest of your utilities, such as humanure, propane, and freshwater, you’ll need the ANSI A119.5 2009 handbook on Park Trailers, which can be had from http://www.rvia.org for $41, as it currently stands. I just ordered my copy, so I’ll let you know how awful it is. Incidentally, there’s another book to buy on that site that looks like almost the same thing, but it costs $250. Don’t buy that one. Anyway, here’s the rundown on the electrical, in layman’s terms, in case it helps. Just think: if you don’t have any batteries, cords or solar hooked up, what better way to learn electrical safely, and have one less Expert to pay for minor house repairs down the line, than to wire your own tiny house? If not now, when? You can always have an electrician check your work when you’re done. However, do not sue me if you survive electrocution, because you read at your own risk!
1. Learn basic electrical concepts and terms:
AC = alternating current; because it alternates it can travel long distances from a power plant to your house. This is what your house is wired with: 110-120V, AC current. 120V current KILLS you if you are electrocuted, so you need to know what you are doing.
DC = direct current; this is what batteries generate, solar generates, and what RVs and boats use, because you don’t have to do anything to the electricity from your batteries/solar/turbine to run your equipment. You can get an inverter to do the job, but they are expensive and they use energy themselves, not to mention they are not 100% efficient at changing DC to AC, so you always lose power. If you’re going hardcore solar, you’ll need a whole lot of DC and not much AC. DC systems are usually 12V, which will not (usually) kill you if you electrocute yourself, which is nice. Incidentally, those blocky things (we call them “wall warts”) that are always connected to your phone charger and laptop charger change 120V AC to 12V DC to charge the phone/laptop battery. I didn’t know that until I started reading on electrical systems. I guess I thought they were surge protectors or something. That’s why phone chargers for your car don’t have a “wall wart,” just a cigarette plug, because they’re charging off of your car battery. Cool, eh?
amperage = amps are a measure of electricity per second. Think of it as the flow rate of electricity, like the flow of water through a pipe.
voltage = volts are a measure of the potential difference of electricity. Don’t cringe! Think of it as the pressure of water in the pipe. 120V AC power wants out of there bad, so don’t let it get you!
power = measured in watts, power is equal to volts x amps. It’s how much work something can do, like horsepower. Now practice. A 60 watt light bulb, plugged into a 120V AC standard outlet, uses how many amps?
resistance = the real-world factor. Some things are harder to pass electricity through than others. A smaller gauge wire will have higher resistance to flow of electricity, for example.
Parallel circuits – built more like a tree, with two trees with “branches” feeding the hot and neutral (respectively) of all the things on the circuit.
Series circuits – like a road trip – hot wire stops at the thing it’s feeding before starting back up on the other terminal and moving on to the next thing, neutral goes from the farthest thing on the circuit back to the panel
3 way switches – these are the kind that work in tandem with another switch to turn things on or off from more than one location. They require 3 way wire to allow the switches to work with each other
Wire – the gauge used is determined by the amperage of the circuit. The smaller the number, the larger the wire, which is not intuitive! The second number denotes how many wires there are, excluding ground (which is not counted). So your standard 15 amp circuit takes 14-2 wire, with 14-3 wire between 3-way switches.
2. Figure out what kinds of things you want to run in your house. Really. It’s a pain, it’s thankless, and it’s really intimidating for those learning electrical, but you really need to do it. It will help you learn, if nothing else. Get a Kill-O-Watt meter (available at the Big Box stores), and start measuring the usage of everything you will use, such as your laptop/computer, cell phone, toaster/toaster oven, microwave, fridge, blow-dryer, electric range/oven, and lights. Do it for days or weeks, not just a few hours while being eco-friendly is foremost on your brain. Keep in mind that things with digital screens on them draw “phantom loads” since they are essentially always on, even when not in use. And anything that heats things, like water heaters, ovens, rice cookers, toasters, microwaves, blow-dryers and clothes dryers, use HUGE amounts of electricity. That’s why people often forgo them or use propane or other fuel sources in a tiny house.
3. You will need to know how much energy you’re really going to use to be comfortable, because if nothing else, you need to know the size of your power cord. An extension cord only carries so much juice before you create a fire hazard or trip the breaker on your host house’s panel. Your three main choices, from what I can tell are: extension cord (look at the rating on the cord), 30 amp RV (3 prong) and 50 amp RV (4 prong)
4. Okay, if you’re still reading, this is what you do next: figure out what actual AC fixtures you want – lights, fans, fan lights, etc. so you know they’ll all fit (inches matter!) and not be overkill. Figure out where you want them. Do you want an outlet in your closet to charge your DirtDevil? How about Christmas lights? Patio lights? (The NEC Article 552 requires at least 1 outdoor outlet). Where do you want to charge your smartphone (hopefully not right near your head, the RF waves are not good) and your laptop? Alarm clock? A nightlight? A box fan for the two weeks in August in the Willamette Valley when you are sweating like a pig wishing for air conditioning? Done? Good!
5. Mark out where you want said lights, switches, outlets (receptacles) and fans. Write on the wall. Where do you want your power to come in? The Park Trailer code says standard is left rear, but I don’t know how they define that for a tiny house. Where do you want your panel so it is easy to distribute all the power coming in to your circuits, and easy to get to? Place your light boxes, switch and receptacle boxes accordingly, securing them in place with sturdy screws.
6. Divvy up your circuits. The Park Trailer article has a category of “2-5 circuits” which I think looked easiest to aim for. Many tiny houses have only 3 circuits. Most full-sized houses have 2 20 amp circuits for the kitchen, with dedicated circuits for ovens, microwaves, fridges, garbage disposals, etc.
What we did in ours:
– 4 circuits (overkill), 2, 15 amp and 2, 20 amp circuits, the bathroom/bedroom and main room lights were on a 15 amp, the living room, stairs and teeny fridge on a 15 amp, an outdoor receptacle and indoor one designed for an oil-heater (huge hog) on a 20 amp, and the kitchen on a 20 amp
– All single-pole switches except for two lights – the nightlight upstairs, and the fan light
– Metal-sheathed conduit from the main power feed to the panel
– A “kill switch” in the bedroom that cuts power to the whole bedroom and bathroom for sleeping at night. We will use an illuminated switch so we know when it is on. We have an outlet on top of our fridge for charging cell phones, far from our bed. Our concession to EMF and RF concerns.
– We designed our bookcase to have a compartment for storing our laptops and charging them, out of sight
– We will be installing only a few 12V circuits in the house – one for the fridge in case we ever get a fancy solar fridge, one for an outlet in the bookcase, the exhaust fan/hood in the kitchen (from an RV) and the water pump (from an RV). The DC panel has breakers instead of fuses (the fused type are the cheapest to get), and will go in the battery cabinet on the tongue. We haven’t wired it yet, but we will!
I was on the website for a Swedish cabin and “barn-house” company named Arvesund, and noted that one of their traditional hunter’s cabins had a spiffy setup: a cast iron stove/kitchen with cook burners, and a stainless steel water tank with spigot that wrapped around the stovepipe, looking almost integral with it. And I thought to myself, I want one. Bad.
We do not like propane dependency in the slightest, and the idea of wood-heated hot water is very appealing to us. We have a propane stove and water heater out of necessity at this time, but we would love to move away from those when we can. We chose to have a wood stove (a Jotul 602) as well as the option of electric heat for many reasons, but control over where our energy comes from is one of them. The establishment tells us wood-heated houses “Are bad for the environment,” “Wood is a scarce resource and burning it pollutes the air,” and “Wood heating is inefficient,” and about wood-heated water systems that, “They aren’t safe.” We thought, what have people done for thousands of years to heat their water? And what happens in a forest fire? And have you checked where we live? We supply lumber to the world – what would be better than using wood that grows here, and returning the ashes to where it was grown? Isn’t that completing the life cycle better than anything you would do?
In answer to the statement “wood heating is inefficient” I would agree that the way we commonly burn wood in the U.S. is. Most Americans are unaware that the way we burn wood now is not the best or even the traditional way, merely the easiest-to-sell way. And if they are aware of the former, they assume there must be a very expensive, over-engineered catalytic woodstove that is the answer. There is no awareness of how woodstoves work, or don’t, as it were. However, the masonry-heater, kachelofen, kakelugn, hypocaust, or rocket-stove (versions of the same thing) that has been used since Roman times is so efficient that the air that exits your house is barely warm, and invisible because all of the gases were completely combusted. Those hand-built stoves are the old way – burn the wood so hot that even the volatile gases (smoke) burn, and store that heat in a thermal mass – tile, stone, cob, water, etc.so the heat is not lost, but slowly radiated back, in the form of conductive heat, the best kind for heating people. Of course, as with life, the answer is not so simple as burn wood, without thinking, as much as you like. Wood-burning fits in well with passive solar and heavy insulation as part of the solution. I see the drawbacks to wood for heating your house or your water as: you have to use your head when heating that way – it is not idiot-proof. You can burn yourself, asphyxiate, destroy your water-heater, set things on fire, or melt them if you don’t know what you are doing. You have to live in an area with many trees to make it ecologically sound. Ideally, you burn your wood as close to 100% efficiency as possible, and with all things tiny-living, the stove should perform more than one function to justify its space. But I can only assume that the reason we are told, in the Pacific Northwest of all places, that wood heat is bad, is out of ignorance, belief that we are stupid, or because they would rather sell us something than have us be self-sufficient. I suspect it is a mixture of all three.
Well, a masonry heater is awesome and I would totally have one in a tiny cabin if that’s what we were building, but thermal mass is heavy. Water is too, but you can drain it out of your house when you move it. Most wood-fired water heaters rely on an existing water tank system to work, which we don’t have (not even a 6 gallon RV one – we went tankless). I looked and looked at Arvesund’s catalogue, and could find no mention of these beautiful tanks or wood stoves. So I emailed them, the annoying American. They were very helpful: Harvia makes the tanks, a Finnish company that manufactures saunas and associated gear. The tanks run around $400, so we will probably wait to buy one until fall. But we have a local Harvia dealer, so we could acquire one easily.
So our current solution to the heating/water heating problem is: use our Jotul 602 but line it with firebricks to insulate the firebox and thereby increase the temperature of combustion to make it more efficient, and capture that extra heat escaping up the stovepipe in the form of mobile thermal mass – a water tank, wrapped around the stovepipe, that we will use for bathing and dishes. And when we don’t feel like dealing with a fire, we use electric heat. Here she is, fresh from the Harvia website:
This beauty holds 22 liters, measures 14″ w x 16″ h x 7.5″ d and her pipe inlet measures approximately 4.5″. Made entirely of stainless steel. Joy! Anyone have one that can comment on performance?
