About this application

This is a planning application for a change of use at 20 Brettenham Road London N18 2ET. Enfield has handled 10,002 applications of this type. This one was decided in 55 days, 6 days longer than Enfield's typical decision time. The site is in a conservation area. There are no previous applications recorded at this address. We hold 689 applications in total for the N18 postcode area.

Why it was refused

  1. The proposal would provide poor-quality accommodation due to the siting of the refuse storage immediately adjacent to the window serving Bedroom 1, resulting in potential noise, disturbance and odour impacts; the restricted outlook and daylight to Bedroom 2, the lack of a direct outlook and inadequate headroom in Bedroom 5, and insufficient usable outdoor amenity space. These deficiencies would result in unacceptable living conditions for future occupiers, contrary to Chapters 12 and 14 of the NPPF (2026), Policies D3 and D6 of the London Plan (2021), Policies CP4 and CP30 of the Enfield Core Strategy (2010), and Policies DMD5, DMD8, DMD9 and DMD37 of the Enfield Development Management Document (2014).

From the council's decision notice.
