Why it was refused

  1. The proposed first floor side and rear extensions, by virtue of their scale, mass and siting in relation to a first floor side facing window serving a habitable room, would unduly detract from the residential amenity of the adjoining occupiers at no.26 Cherry Grove, by reason of loss of light and overshadowing leading to an overbearing addition that would impact negatively on the outlook of this adjoining habitable room. The proposal is contrary to Policy D3 of The London Plan (2021) and Policies DMHB 11 and DMHD 1 of the Hillingdon Local Plan: Part Two - Development Management Policies (January 2020).

From the council's decision notice.
