What is required to build

[Guest]

I would not build on a slab in Puna. It is too rainy and humid here and the bugs will move in beneath the slab and into your walls. You need to be off the ground at least 3 feet with ventilation underneath to get up out of the damp and the bugs. Also if you discover that you have drainage problems during a heavy downpour after you have poured the slab, you are screwed. Post and pier is the only way to go. Just take the slab home floorplan and frame a post and pier floor instead of pouring a slab. You will be glad you did.
