Quite an old shed, about 6 feet by 4 feet. I've managed to dismantle it -- and it is still just about in one piece! By which I mean, I think you can put it back together successfully. It is, however, far from perfect. One small bit of the corner of the base has rotted. At the bottom of the door, too, and a few other places, the wood is worn away. The roof felt will also need at least some patching. I took some of the slats off as part of getting it apart and they can mostly be reused but a few replacements might be needed.
It would also need to be collected with a fairly sizeable vehicle. Please get in touch if it would be of use to you.
