Retired builder's site shed. It's having a rest now after travelling about. I myself have pitched it in 3 different homes, and like me wants to stay put. I have no idea who originally made it. Custom built hardwood frame!
3ft foam board extension by me. Sadly the tongue and groove, polythene and felt composite roof had to go in 2006. I was running out of buckets to catch all the leaks. Link at: homepages.enterprise.net/jayjay/shed.htm
