The shed had been dismantled in order to take it to the tip. We saw the bits strapped to the top of a van and asked the owner to take it to our allotment instead of throwing it away. Several people have helped with labour and materials contributions (thanks all!) The original shed had one window and a flat, low roof. We added two big windows, raised and sloped the roof. We put perspex in half the roof area to make the shed very light and airy
