Interesting working method. This booklet is both for the D.I.Y.'s and technically interested . This is a booklet of 3 different plans of greenhouse. The first is a small angle-roofed 2 x2.5 m design featuring a removable upper unit which can be used as a cold frame for germination in Warmer months. The second design is a 4 x 3 m based, gothic arch type with a 2.6 m height at the peak centre.
