28 Queensbury Road: a guideline did not resolve neighbour harm
25/0953; APP/T5150/D/25/3368061 · Appeal dismissed, 1 October 2025
The first-floor rear extension raised concerns about light and outlook at No. 30. The inspector accepted the assessment of likely harm despite the applicant referring to the SPD’s 45-degree guidance. No detailed lighting evidence demonstrated otherwise.
What to check: A guideline is only part of a planning assessment: show the actual window relationship and provide evidence where light is disputed. The decision also explains that possible PD rights elsewhere at the house did not make this submitted scheme acceptable.

Questions about planning in Brent
Do I need planning permission for my project in Brent?
Some house extensions, loft conversions and outbuildings can use permitted development rights in Brent, but size alone does not establish eligibility. Check the property type, previous extensions, planning conditions and the rules for the proposed work. Householder rights do not apply to flats. Conservation areas and Article 4 directions restrict particular rights; they do not automatically require an application for every change. Listed building consent is a separate requirement for works affecting a listed building's special interest.
