In 2006 & 2007 we built our 24 x 48 with a 24 x 24 ell garage, 1,750 square feet on the 1st floor.
Recommend:
6 inches of underfloor styrofoam insulation
Radiant floor heat tied to 6 inch steel 6 x 8 sheets.
Dyed & dually reinforced floating slab
Metal roof
Wish I had plumbed a hose inside.
Consider a Timber Frame with Super Insulated Panels or SIPs. The overall cost is similar to stick building.
Room for 7 cars with 1 lift, 8 cars with 2 lifts (2nd on back order currently)
