I need some expertise, advice in making a decision about the base of the home I hopefully will be able to build this summer/fall.
I am anticipating building a small home for myself that initially will be about 1000 square feet (compact and well insulated). I live alone on 21 acres and I definitely need to get out of the hovel that currently is called my residence. The structure will be very basic — kitchen, bathroom, two “bedrooms” (one a bedroom and one an office) and then some large central room. Basically I want to have a 16 x 28 main room with a gable roof (4/12) and then a shed roof (also 4/12) off both sides for 10 x 28 areas for office, kitchen etc. Exterior walls will be framed with 2 x 6 24″ OC.
I am laying this out so that at some later time I can build off the north end (down a very slight slope) of the main part and put in other bedrooms and a living area that overlooks a valley.
So what do I do for the base of the home — foundation with a crawl space or put down a slab? I can think of lots of pluses and minuses for both approaches!
What are the approximate comparative costs of each system based on a square foot basis? Any comments?
If I do a slab, how do I get the wood 18″ from ground line to avoid decay and termites, carpenter ants etc?
If I do a slab I will consider coloring the ‘crete and also adding reinforcing fiber to minimize cracking. Any comments on this?
