I wanted a shed that I could also sit out in and have an evening beer, after trawling the internet for ideas I saw that in Germany they have sheds with seating areas attached so that's what I designed.
One of my key features I'd put down on a cigarette paper was a green roof, I looked at loading tables so that I could build it strong enough to carry 1 tonne per square metre. Couple of freebies, an oak stable door which was water damaged but I repaired it, and the stained glass window that my wife made at evening class about 10 years ago but it lived in a cupboard since and I wanted to show it. Careful measuring meant barely any waste. Homemade seating as IKEA couldn't get any stock
