SVreX said:I spent 10 years of my life volunteering full time with Habitat for Humanity. They build all over the the world.
Part of what they need to do is assess the best and most cost effective techniques in various parts of the world. They have an entire department whose job it is to work with varying techniques called the Appropriate Technology Department.
The job of the Appropriate Technology Department is to identify techniques that utilize locally available resources- labor, materials, etc.
I worked in that department for a long time. That means I built with a lot of strange stuff. I’ve used ICF's, SIP's, Sod, Hay bails, Adobe, Stone, Timber, Log, and Rubble. I’ve also used hand made blocks, compressed soil bricks, clay tiles, slate, waddle and daub, thatch, and several really weird ones like glass bottles, hand made cement tiles, tin cans, tires, soil roofs, and fly ash.
In Papua New Guniea we carried a sawmill 30 miles into the jungle on foot and built houses on stilts from lumber we timbered directly on the site
We also got donations from various manufacturers who wanted the exposure of highlighted their products. Residential metal studs, truss wall, and all kinds of variations of siding and finish products. Octagonal houses, Yurts, tree houses.
I’ve even done timber framing WITH Tedd Benson!
I really doubt there are very many people who have been exposed to more building methods than me. It’s been a thrill ride, and I have thoroughly enjoyed it.
But I wouldn’t recommend almost any of these techniques to the vast majority of people. Simply not a good fit.
Unless you live in the jungle!
What I found is the supposedly faster SIP panels took forever especially in the cold weather when the glue flowed like solid rocks. Each panel took me more than an hour to align and I had to be extremely creative to do it that quickly.
ICF's on the other hand went together like lego's . I made a mistake in trying to save the scraps rather than tossing them. It just threw out of alignment the places to screw sheet rock into. Added a couple of hours to sheet rocking. But easily enough dealt with.
Just for information your map about Termites is off. They are rare to non existent north of the Iowa border. Here the big issue is carpenter ants. Yes the Borax or whatever they put in keeps them out. But to be safe I coated all of them with a thick waterproofing sealant. ( That I got in my hair)
In Retrospect if I ever build another house (I won't ) stop at the foundation I'll do all the walls in ICF's
Nor would I do a double timber frame. Massively too much work. I'd just do the rubble pattern on the exterior. I really like how that looks and while it took longer than bricks or stone it wasn't really too long. not fitting it inside of the timbers would have saved a significant amount of time.
I did do the traditional masons obscene gesture in stone on several walls. Some see it, most dont.
One other idea That I had that I wish had worked better was the rolled roof on the lakeside.
I grew up looking at one on the other end of the lake.
the cedar shingles lasted almost 50 years before they put shingles on.
Steam bending all those shingles took forever plus several failed to remain bent.
PS Thank you for your work with Habitst for humanity.
