Floor and Ceiling questions for new structure

[lunar151]

I think at this point, Im just going to pour a 1'x1' perimeter foundation, 6" in ground, 6" above and run a support beam down the middle, and run joists on top with 1" plywood for the flooring. Keeping it low profile to the ground. Running joists at 16" on center will make for a solid floor I would assume.

Bad idea... solid slab would be much better, with 12"-16" turn downs and 4"-6" in the field, decent sized wire mesh (4x6-ish) on saddles.

Leave 4" above ground, put a french drain around the perimeter.

Using 16" OC floor joists will just end up making a dandy resonant "drum head".

Coupla' things to ponder...

Where will you bring in power?
What will you use for HVAC/fresh air?
Have you pulled permits?

Thanks for the reply, I was trying to get away from ordering a concrete truck but I guess Ill go ahead and do that. If I just poured a perimeter foundation I could get away with getting a couple one yard buggies. As far as permits, I would love to pull one but my parents house has been added and added on through out the past hundred and fifty years and if I pulled one I was afraid the county would bust my parents. The dimensions are on the smaller side, 11'x21' roughly(its trapezoidal)

Ok, I think i finally figured out what wes means when he talks about the ceiling. Since isolation is not an issue, "fluffy" fiberglass inbetween the joists with fabric covering and holding the fiberglass between the joists? 8' exactly from floor to bottom of joist? Then heavy card stock where the cloud wouldnt be. what does he mean when there will be extra fiberglass in the corners?

Ok, now I understand the ceiling construction of the design Im building, see link I posted above. Wes says to put 1' of fiberglass stuffed inbetween the ceiling joists and the 8' measurement will be from the floor(concrete slab) to the rigid boundary above. If I use 2x12 ceiling joists(to help keep the fiberglass uniform) and put a layer of osb on top of the joists(rigid boundary) to seal the room in, That makes my room 7'. Seems low right? But I guess like Ethan said, 95% of the ceiling is fiberglass at that point.
