Main issues, as the Inspector framed them
- whether the proposed development would constitute permitted development under Schedule 2, Part 1, Class AA of the GPDO, having regard to limitation AA.1.(h)
- if permitted development, whether prior approval should be granted considering the conditions set out in paragraph AA.2. of the GPDO
What decided it
The lower ground basement void does not constitute a storey for Class AA purposes because it is below ground level, used only for storage, has no internal staircase, and is not a habitable room, therefore the proposed first floor complies with the floor-to-ceiling height limitation.
