Built on 9 pillars, Double glazed and Will withstand quite a bit of pounding. Part of the side is a window made from polycarbonate roofing. Brown on the outside so you can't see much going on from the outside.
All hand built from mainly recycled material and stuff left over in the garage such as pieces of plaseterboard, laminate flooring, floor insulation and loads of dpm. The back wall is a fence panel that has been reinforced inside with 3 x 3
