- Whether the proposed extension would comply with the permitted development limitations set out in Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015
What decided it
The combined existing and proposed extensions would extend 7 metres from the original rear wall and include more than one storey, exceeding the GPDO limitation of 3 metres for multi-storey extensions, and therefore the proposal does not qualify as permitted development.
