Building a new house: Planning stage
I’m planning to build a new home in Pender County, NC, near Burgaw. It’s in the southeastern part of the state near the coast. It’s in climate zone 3 and below the “warm-humid” line. Plain, super-simple rectangle, interior dimensions 39×50 (very open floorplan). Front door facing N (just slightly NE). Simple gable roof with the ridge running east to west. Wrap around porch across the front and down the east side. As you can imagine, I have so many questions, I’m not sure where to start. Regarding the foundation, I would like the house elevated as it would be with a crawl space, but I understand the issues / potential issues with building and sealing crawl spaces correctly. Would a raised slab be a good option? Do I understand correctly that the very basic idea is to build a block wall the size of the footprint, backfill it, compact it, and build the slab on top? What are the pros and cons of raising a slab like this? How high can it be raised? Also, what is the best method for insulating a raised slab? Rigid foam underneath? Finally, should I maintain this same thread for all questions about the entire project, or should I create a new thread for each question about a different aspect?
