I agree with STM. There's no story here, or if there is - it isn't clear enough.
If the thread title didn't have 'shed' in it, I would be wondering what that thing hanging in the middle was.
(And even now, it's just - "Oh, it's a shed - any number of weird things could be in there". I still don't know what it is. I assume it's for cleaning a fireplace, but it would not surprise me if I was wrong.)
