Planning appeal decision
44 Mount Pleasant, Ruislip, HA4 9HG
Planning appeal 3314443 at 44 Mount Pleasant, Ruislip, HA4 9HG (London Borough of Hillingdon) was dismissed on 10 November 2023 by Inspector Howell M, by written representations. The main issue, as the Inspector framed it: Whether the Council's decision to refuse to issue a Lawful Development Certificate was well-founded, turning on whether the conversion of the roof space was lawful on the date of application and whether the proposal amounts to development works permitted by Article 3, Schedule 2, Part 1, Classes B and C of the Town and Country Planning (General Permitted Development) (England) Order 2015.

Main issues, as the Inspector framed them
- Whether the Council's decision to refuse to issue a Lawful Development Certificate was well-founded, turning on whether the conversion of the roof space was lawful on the date of application and whether the proposal amounts to development works permitted by Article 3, Schedule 2, Part 1, Classes B and C of the Town and Country Planning (General Permitted Development) (England) Order 2015
What decided it
The proposed works, particularly the rear dormer combined with the hip-to-gable conversion, would constitute a new roof structure rather than a permitted enlargement, and would breach the conditions of Class B of the General Permitted Development Order by failing to maintain the rear eaves and extending beyond the original external wall.
