Missile Silo Houses

Further to my post on missile silo homes, here's a real estate agent that specializes in missile properties and also underground communication centers. The latter are more interesting to me, because the holes in the ground mostly filled with water give me the creeps. One only costs $67,000. I think they could have a few more pictures of the properties for sale on the site.

747 House

How's this for building material, a scrapped 747 jumbo jet. In case you missed this like I did in April, according to the article, a scrapped 747 costs about $100,000. The woman talked about in the article is building a multi-million dollar home with hers, but I imagine something more modest would be possible. I wonder if all the seats are still in there. You could build a great home theater room.

This article about the same house says the 747 cost $40,000. That starts to sound feasible. Just a big problem moving it to the construction site.

Wall-framing with 2x6's

Your tax dollars at work. Here is some info on cost saving building by using 2x6's instead of 2x4's. They use a lot of specialized vocabulary which I don't understand like "drywall return" and "scabbed", but if you are ready to build your house it is worth a read.

Washer-Dryers

Another I don't understand why everyone doesn't have one. A machine that washes AND dries clothes. If you have an automatic washer and an automatic dryer, why not go totally automatic and have it dry clothes too. It costs about the same as a washer and dryer together.

If you want to really save water there is the wringer washer. But then laundry is a whole-day affair. Start with the cleanest and end with the dirtiest using the same water. My mother always had a wringer washer when I was growing up. I wonder when water will become so scarce that we will be back to wringer washers. Right now I think about the only place you can buy them is at Lehman's. They have one made in Saudi Arabia. I guess even with all that oil, water is still at a premium in the desert.

Composting toilets have come a long way.

Forget about water saving toilets. I think no water or composting toilets are the best way to handle human waste. All that manure needs to get back to the earth. There are amazing systems that actually do this. The cost depends on how much work you want to put into it. At the low end is Jenkins' bucket system as described in his book Humanure (available free online). But I could see that taking out buckets of the stuff would get old fast. And it reminds of the untouchables caste, whose job was (and still is in some parts of India) to take out buckets of feces from upper caste homes.

I like the Envirolet. They have normal looking toilets that have a duct that takes the stuff down to a floor below where the composting takes place. The cost is quite high, but then if you compare it to installing a septic tank, it is reasonable. Only problem is getting the building inspector to accept your not putting a septic tank in. There are lots of composting toilets to choose from for example Sun-mar, Biolet, Phoenix, and I believe the Clivus Multrum has been around for a long time.

And then you have to have a system for handling grey water. That will be in another post.

Build a cabin for less than $4000

A good article from Mother Earth News on building a cabin with boards. The guy does a pretty good job of describing the process. There are just a few things I don't understand. Probably if I read it over and over again I would get it. The $4000 doesn't include plumbing, fixtures or electrical stuff. I guess you live by candle light or use solar electricity.

These guys say you can build a nice log home for under $10,000. I would check them out before I bought a log cabin kit.

Another housebuilding blog

Here's an interesting blog about building a house. He says he is the one-man crew for his contractor, so I guess it's a self-build.

Las Gaviotas - Colombian town of the future

This is an interesting place. An engineer dedicated his life to making a barren, unlivable environment into an oasis, both literally and figuratively. Wind and sun was used to provide energy to a village in the Colombian llanos and then they brought in Caribbean pinetrees which made the soil attractive to rain forest plants turning the area back into the rain forest it was thousands of years ago.

The most significant invention is a simple hand pump capable of tapping aquifers six times deeper than conventional models, but requiring so little effort that children can operate it. In normal pumps a heavy piston must be raised and lowered inside a pipe. Gaviotas engineers realized they could do the reverse; leave the piston stationary and lift an outer sleeve of lightweight, inexpensive PVC tubing instead.

The word llanos translates to plains, but the Colombian llanos are nothing like the fertile plains of the U.S. Midwest. Roads are barely there in the dry season and completely impassable in the rainy season. And in Colombia anytime you travel outside the cities and larger towns, you also travel back one or two centuries in time. Las Gaviotas just leaped over the petroleum fueled era.

For 6 months I lived in Villavicencio, which is where the llanos begin. It was 1975, but I knew nothing about Las Gaviotas, which was started in 1971. We lived in the second floor of a house. It had a nice, big patio where I washed clothes in the lavadero (a concrete water container with a washboard).

The strangest part of the house was the decorative brick walls. It had holes so that a breeze could come through, but also the mosquitoes could come in. We had netting for the baby's bed, but not for ours. We sprayed insecticide every night around the bedroom, a very common practice in tropical areas. Nothing worse than hearing the whine of a mosquito when you are trying to sleep. There was no hot water, the norm for tropical areas, in Colombia at least. The water came off the mountain, so it was very cold. I could not take such cold showers, and there was no tub, so it was sponge baths for me and the baby. Solar water heating would have been so simple to install. I wonder if people are using solar now.

Slipforms on steroids, ICF's (Insulated Concrete Forms)

OK, technically these are just forms not slipforms. But basically it's the same idea. You build the forms like legos, and then you fill them with concrete. ICF, insulated or insulating concrete forms. I haven't been able to find anywhere if you can fill the forms with papercrete or rocks and cement or rammed earth, which would be more the self-builder way. For sure you could not fill with cob, as it needs to breathe. I think the self-builder would want to go one row at a time, so even though the cost is comparable to a wood-frame house for a self-builder these would come out costing a lot, as you would have to buy them all at once. Unless you lived near a plant and hauled them yourself and maybe even picked up seconds.

Also all that concrete thermal mass is lost, because the insulation is on both sides of the concrete. They should make the inside panel of something that is permeable like wood not insulating material so that the concrete mass could help to store heat in the home modulating the temperature.

It seems to me the best system is Durisol, which is made from a cement-bonded wood fiber material with an insulating material inserted into the exterior side of the block. Here's a good article from Buildersnews. Lots of info here at the ICF Builders Network. Also the Green home builder has some info and links.

Round house in Wales

A little bit primitive for me--a truly low impact house, but they built it for about $7000. Interesting how they used a pond liner to make the roof waterproof. And they are growing grapes on the roof. Who knows, maybe this is the way we (you) all will be living in 50 years.
