Why it was refused

  1. The proposed development, by reason of its excessive width, depth and cumulative massing, would result in an overly dominant and disproportionate form of development that would fail to appear subordinate to the host dwelling. In particular, the extension would project significantly beyond the established rear building line and would fail to respect the prevailing pattern of development within the locality, to the detriment of the character and appearance of the host dwelling and surrounding area. The proposal is therefore 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 (2020).
  2. The proposed development, by reason of the additional 2m projection of the side/rear extension along the boundary with No. 26 The Drive and the increased width and depth of the rear extension, would result in an unacceptable sense of enclosure and loss of outlook to the occupiers of No. 26. The proposal would therefore cause material harm to the residential amenities of the adjoining occupiers, contrary to Policy D3 of the London Plan (2021) and Policy DMHB 11 of the Hillingdon Local Plan: Part Two - Development Management Policies (2020).
