First of all, I am new to this board so thank you to any that reply. I recently built a deck that has a concrete slab under it. I would like to enclose the area under the deck for storage. The way the deck was built differs slightly from the way it was originally designed. The design called for the support posts to be inset about 9" from corners and edges with the joists/decking cantilevered. Well that wasn't able to work so now my posts are only inset about 2". I was orginally going to use cinderblock, but 1. I can't afford to hire someone to do it. and 2. I don't think it would work with how the posts are. I have read a little about permanent wood foundations and similar ideas. My main question is can it work for my deck? Can I construct PWF walls in bewteen my posts? I wil need to backfill along two of the 4 walls that will need constructed. The other two will be exposed. Like I said the enclosed area will only be storage (much the same stuff as found in a shed). I have attached a pic hopefully showing in better detail what I hope to accomplish. Lastly, if I can do a PWF, is the space better or worse off if it were to be conditioned air? Thanks!
