Instead of pouring a concrete slab for your floor you can have it built out of engineered i-joist. They do this by building concrete footings with a stem wall on top of that. They will then pour footings for pony walls or post and beams to support the i-joist's. They will then run the joist over the pony walls which will create your CRAWL SPACE. This also gives you the ability to fully insulate underneath the floor and have access to your plumbing if you run into problems with that later on. its also a little more forgiving when your children take those tumbles to the floor.
