This little double-gated car-park garden (I've slipped the camera through one gate to look at the other) is occasionally lit up (as it is here) by a ray of sunlight, but I can't imagine that it sees much sun. Sandwiched between college utility rooms and a day-care centre for children and young adults with severe learning difficulties, this car-park is always firmly barred, and presumably belongs to the upstairs flats. But whose is the tiny garden? Is there a concierge tucked into a buildings office, cycling to work, fixing problems in the flats and nipping out each lunch-time to water the plants? The ladder hints at some practical role lurking back there.
I've never seen anyone (bar once, a window cleaner's van) exiting or entering this car-park, so for now, a mystery garden.
