The building is 28' x 36'. Conestoga has 8', 10', and 12' first floor heights shown on their web site. This is their 10' option (slab to bottom of the joists). It has a 10:12 pitch roof giving it a total height of ~ 22'.
The attic trusses combine 2x8 and 2x6 construction. The all chords of the scissors trusses are 2x6.
The insulation under the agricultural roof is a Conestoga option. Originally I was going to have Conestoga install the base and pour the concrete slab. But my house builder, Chesapeake Custom Builders, inc came up with a better price combining it with a couple other concrete jobs on the house. In addition, wire mesh and vapor barrier are extras for Conestoga, but standard for my builder and I had confidence my home builder would ensure the slab was cured the way I wanted.
