I built this garden shed for my wife using reclaimed 1"x6"x7' treated fencing. I ripped the boards in half and used them for the uprights, trusses and perlins. the floor, siding, and trim are also from the fencing. Everything including the doors, window, roofing and porch poles are reclaimed from our old homestead.
The corner of the barn in the background is 30"x44" and made completely from reclaimed material. Almost everything in our yard and garden come from something that has been reclaimed.
