We built a slab foundation house with Rob's ProTec SIP (structural insulating panel) for the walls (cement board sandwiching foam), including several interior walls, and a SIP metal roof (sheet metal sandwiching foam). And a lot of substantial help and advice from Rob for which we are still very grateful. The walls are attached to the slab by galvalume C-channels and the channels to the slab with foundation bolts and a thin insulating layer next to the concrete. The posts and beams are all galvanized steel. We felt the slab construction was simpler and appropriate for the materials. Our goal was to provide nothing for the termites (well, the doors were an exception) and building a non-tasty post and pier foundation seemed much more complicated for we owner-builders. Probably not so intimidating for someone actually well experienced in construction.
