Why it was refused

  1. The proposed subdivision would result in two three-bedroom family dwellings that fail to meet the minimum Gross Internal Area requirements set out in Policy D6 of the London Plan (2021) and Policy DMHB 16 of the Hillingdon Local Plan: Part Two (2020). Each dwelling would provide insufficient internal floorspace for a three-bedroom, four-person household, resulting in a substandard form of residential accommodation detrimental to the living conditions of future occupiers. The proposal is therefore contrary to the Development Plan and the objectives of Paragraph 135(f) of the National Planning Policy Framework (2024).

From the council's decision notice.
