We had been collecting discarded windows over the last few years, planning on building ourselves a little hobby greenhouse.
We decided on a gravel floor, so we marked little out, dug down below the ground laid down weed barrier and filled it in with some grade a gravel.
We framed out our walls, measured out the openings to fit our reclaimed windows.
Framed up the roof.
Installed the windows, and shimmed them.
Roof on. Shingles on.
