23 Manor Way: extensions that retained the house’s character
24/0766/HD · APP/E5330/D/24/3348377 · Appeal allowed with conditions, 21 February 2025
The side and rear extensions, partial basement and other alterations were accepted in the Blackheath Park Conservation Area. The inspector considered the stepped form and roof design sympathetic to the Arts and Crafts house. Conditions required landscaping and tree protection, construction management and matching materials.
What to check: Explain how the original building remains legible and draw the relationship to neighbours. Check the conditions before work; the permission did not settle every construction detail.

53 Southend Crescent: acceptable light did not settle outlook
23/2014/HD · APP/E5330/D/23/3329981 · Appeal dismissed, 1 March 2024
The rear extension was judged too tall and bulky for the house and its unextended neighbour. Although the inspector did not find significant harm to light, the long boundary elevation would dominate the neighbour’s outlook. No applicable PD fallback had been demonstrated for this scheme.
What to check: Assess height and enclosure as well as daylight. General references to PD rights or other rear extensions do not establish that the submitted design is acceptable.

Compare the property type, works and application route. A scheme involving flats or several alterations is not directly comparable to a simple house extension. Read the archive's coverage and limitations.

Questions about planning in Greenwich
Do I need planning permission for my project in Greenwich?
Some house extensions, loft conversions and outbuildings can use permitted development rights in Greenwich, 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.
