Options for building a new garage

I tend to forget some people live (stay) in the city or burbs!! not the country.

if a pole building. this is what I do. pour a concrete slab ( floor), I then come in between the poles with a 2 x4 stud walls. 16 oc and insulate between. sheetrock over that. walls are then insulated. I do it all. no labor. sheetrock is cheap crab but it makes walls. put insulation under the roof tin for insulation and vapor barrier. like they said, be sure it is tall enough for lift, and concrete will accommodate the lift. add figerglass to concrete for strength. plastic sheet under concrete to keep cold, dampness from comin thru it.
