DIY Plans for a half greenhouse, half potting shed structure 6ft (1.8m) wide x 8ft (2.4m) long. It is a barn-style shape with a gambrel (Dutch) roof, and boasts a timber split leaf stable door (Dutch door), allowing the top half to open independently from the bottom half.
One of the side-walls is solid up to the roof, which is a good wall to fix shelves to for the potting shed half of the building. The opposing side wall, roof and back wall are mostly greenhouse plastic film cover.

It is a very solid, easily changeable structure.

The downloadable PDF file contains 35 pages with loads of drawings, pictures, and plans with a step-by-step construction guide.

All dimensions throughout this project are given in both inches (standard) and metric (mm) units.
