Hello, okay, I'm in central Texas, San Antonio and want to begin working on my dream shed. I've finally decided on a 16x24 barn style with either 7 or 8 foot walls. A long time carpenter buddy of mine said I'd be making a mistake if I didn't go with a concrete slab foundation. Honestly, I was considering going with a pier n beam foundation with 4x4 skids sitting on solid concrete blocks with a gravel bed underneath it all. Then I was going with 2x6's for the floor joists with 3/4" ply sitting on it all. Of course everything down below will be treated lumber.
So............please help me decide. Could I get away with pier n beam or should I go with a slab? I received three quotes today for the slab pour $1500, $1300 and $1200.00. I know, I know DIY right, but I'd rather let a pro do this then I'll take over with the actual shed construction.
I know the cost of treated lumber is not cheap..........so cost does have a role in this decision......thanks.
Central Texas is known for expansive clay soil. This may be more of a problem for a house, but if this is a dream shed you really should determine if expansive soil is a potential problem. If it is, you need a special foundation design else the shed floor is likely to crack (if concrete) or go out of level if you use pier and beam.
