Fish Guy, Yeah, We have three heat pumps. The two largest are for chilling the roof so we can retain snow for the aesthetics. I realized that the south side was just too sunny and the expense would be prohibitive but the north side isn't that big of a challenge. (Just going along with your gag.)
I'm not claiming the house isn't big but it isn't really as big as it may look. The part nearest the three roll up doors is sitting on a 57x48 ft rectangular slab plus a triangle on the far end where it adjoins the actual house, about 3000 sq ft. The ground floor of the house part is only about 2000 sqft not counting covered or enclosed porches.
There is a second floor to the shop part which is reduced in size due to roof line. I put walls where the 12:12 pitch ceiling came to within 5'6" of the floor. At 6'2" my shoulder hits a wall before my head hits the ceiling.
The whole shop/shed/garage thingy is an open span steel bld with 12 ft walls and a 12:12 pitch roof. It is typical steel bld construction with engineered steel trusses and all the other "red iron" from Miracle Steel. It is a 24x36 open span steel bld with I beam columns. The 3:12 pitch 21x48 shed roof is attached at 12 ft height on the south side. It all has 2x6 purlins on 2 ft centers setting in steel pockets.
Interiior walls are not load bearing, just cosmetic. The roof uses 2x8 on 2 ft centers.
I had contractors to help and it took me about 3 years to get enough done to move in. See Oklahoma Farmhouse thread at countrybynet.com
