Alrighty, cell phone pics...but you'll survive I'm sure. When I bought the house, this summer, I bought the lot next door which came with my driveway to the back shop, 'three' carports and storage shed. For the sake of clarity, I'll refer to the closest carport as the "single" carport, and the one in the back (with the trailer) as the double carport.
The single carport is built on a poured foundation. The back wall has a full-length poured foundation, but I haven't dug down to see how deep it is. Both the house lot and the spare lot have a poured perimeter foundation around them and the rear posts of the car port are built onto this poured perimeter foundation. The other posts are built on poured concrete posts that go into the ground:
The wooden posts go up to cross beams, upon which there are roof joists followed by plywood sheathing and then a metal corrugated roof.
The double carport in the rear seems to have been built as more of a 'temporary' structure, in that it could be taken down without much difficulty. The front posts are on the same poured foundation shared by the rear posts on the other carport. You can see the line of concrete going along the whole front.
The middle posts, however, are on simple concrete pads:
The rear of the carport has a wood beam laying on the ground, and the rest is built on top:
I'm quite certain this double carport was acquired from another location, as there is a big door cut into the back wall which goes to nowhere, and serves no purpose. Well, at least the metal used for the back wall was acquired from somewhere else!
Build structure is also different from the single carport:
The single carport measures 32' long, 8'9" in between the posts. The double carport is 26'8" deep, and measures 11'7" between the posts on one half, and 12'5" between the posts on the other half. (So total is 24' wide).
