Why it was refused

  1. The proposed rear extension by virtue of its depth, height and siting is considered to have an unacceptable impact on the amenities of the neighbouring property No. 12 Langley Crescent by way of overbearing impact, over dominance, loss of outlook, light and overshadowing. In the absence of a BRE daylight and sunlight assessment, the application has failed to demonstrate that the proposed development would not lead to a loss of light, significant overshadowing or overbearing impact to the adjoining neighbouring property number No. 12 Langley Crescent. The proposal would therefore be contrary to Policy BE1 of the Hillingdon Local Plan: Part One - Strategic Policies (2012), Policies DMHB 11 and DMHD 1 of the Hillingdon Local Plan: Part 2 - Development Management Policies (2020) and the National Planning Policy Framework (2024).

From the council's decision notice.
