Our lot (in Alabama) will require approximately $20M in site prep due to bringing "good dirt" in to provide a decent foundation, and to level the lot. Realize that crawl space is more expensive, but due to the leveling, wondered if it was "six of one or half dozen of the other". We would like to have regular hardwood floors on the first floor (of a two story plan.) The square footage on the bottom floor is between 2035 sq ft. Cannot find any resources to help us decide, and don't have a clue. Builder wants to do slab foundation...typical in our area.
