Avoid Planning Permission
This building is under 2.5m high.
Why does this matter? Well, under permitted development rights buildings under 2.5m high can be placed as close as you want to a boundary (eg. a fence line) without planning permission. Buildings that are over 2.5m high, however, need to be placed over 2m away from any boundary
(eg. a fence line), which means that with taller buildings you end up with a lot of space behind them. If you want to find out more about permitted development rights see our planning guide
