The greenhouse was built using 4"x7" posts cut at 22.5 degrees to form the corner posts. 4"x9" headers, 3"x6" hip rafters and collars, with 1"x4" strapping. The only items that were purchased were the bottom pressure treated plates, the plastic, the corrugated plastic roofing, and the bolts. We also fabricated the gusset plates and the peak bracket.
Overall width is 11' and wall height is 8'. The roof slope is approximately 4:12.
