Nugget - we used a 2x12 for the ridge, but because it has a 14' span the dip in the roofline is not as pronounced as yours. It's still pretty but not as extremely cool as yours.
Thanks, but yours dips just enough. My father in law laughed at the idea of building inspectors seeing it (ours, that is) and condemning it! Brand new, and the roof is already sinking haha!
The building is totally closed up now. I have to finish trimming the corners and windows, finish sheathing the interior walls, then paint and start building the coop section inside.
The interior coop area will basically be a 10x6 box formed with plywood. 2x6 framing for the ceiling will allow a storage loft above that. Gallery is here http://www.gbdg.net/g2/main.php?g2_itemId=349 - More pics soon.
The run is 8x12, framed with pressure treated fir, wrapped with hardware cloth. The roof is Ondura from Lowes.
We poured concrete piers using sonotube forms. There are a couple pier blocks + 4x4 PT in the middle under the center of the structure and in the rear, which were set in a small base of concrete for stability.
Before winter I'll pour a small pad in front of the door and build stairs, as well as set a couple more pier blocks at the front/center and on the sides - just for stability and support.
