Here’s a good one.
As you can see, the little wall (4foot 5?) leads straight onto the roof of the building. How long before some punk kid decides to show off to his mates and shimmies along the wall onto the three story building?
The best bit is that is a retaining wall. Lean on it, look over, and you look straight down THREE stories. For a primary school, it’s the worst bit of design I have ever seen.
