This picture reminds me of a scene towards the end of chapter four in Harry Potter and the Half Blood Prince. Dumbledore had just brought Harry from Horace Slughorn's "borrowed" home to the Weasleys property. They were standing outside and Dumbledore beckoned Harry to join him inside of a "run-down stone outhouse where the Weasleys kept their broomsticks. "The two of them then proceeded to have a serious discussion about a variety of topics while inside the shed.
Although this particular shed is made of wood and not stone, I am strongly reminded of the Weasleys shed. First, the stove pipe is crooked, reminiscent of something that has been haphazardly added to the shed. Then, there are the walls that bow outward instead of stand up straight. That is very much in line with how Ron's house was described and appeared in the movies.
Lastly, the shed is small. The Weasley's home may be bursting at the seams with children, but the home itself is relatively small. I have a feeling that Ron would feel right at home in this backyard. I also wouldn't be the least bit surprised to see garden gnomes sneaking around this shed!
