It's just a very ordinary, tiny 6x4 shed that came with my house. Tarted up to make it more of a feature in a very small garden. Basically slapped a bit of paint on, added a fake window frame, a shelf on the side for growing flowers, and topped it off with a mini-weathervane.
Not quite finished yet - need to tidy up the edges, touch up a bit of paint, clean off the hinges, etc.
