I forgot to mention, I just signed a contract for a turn-key job on a new shop/storage room.
It will be all steel, 24x30x10 on a concrete slab, with insulation, one interior wall (separating rear third for storage), 4 windows, 10x8 garage door, plus two 3'0" doors, and the cost is $11,220.
I already have a completely enclosed two bay 16x24x10 tractor/mower shed out back with two 10x8 garage doors, built over a 4" crushed granite base.
Implements are stored outside.
