I expect over the years the sheds have got bigger and bigger, and the productive gardens smaller and smaller. I like this shot for the variety of tones and how it makes you explore the photo.
it might not be pretty, ,but it does look quite orderly and well kept. I lived in Walthamstow as a student - our back garden was totally overgrown and still had an anderson shelter in it. I guess the neighbours were not very impressed.
