You'll need to visit Simon Kirby's blog for the full photo story of its construction from pallets and packing crates, but this image gives you a taster of the nearly-finished product. Simon, who calls himself a bit of a "shedonist", says:
In all it’s taken me five weeks to build and has cost me £40. I love it. I wouldn’t have a bought shed if you paid me. It’s very environmentally-friendly because the pallets just go to land-fill and it’s a wonderful bit of self-expression, but not everyone can afford the 100+ hours it took to build so it’s probably not for everyone.
More power to your elbow, Simon!
