Why it was refused

  1. The proposed development, by reason of the introduction of the side dormer extension, would result in an unacceptable and visually intrusive alteration to the original roof form of the host dwelling. The side dormer would interrupt the previously unbroken side roof slopes through their cumulative impact which would erode the simple and coherent roofscape of this group of properties. The rear dormer due to its size, unsympathetic design would thereby appear as a discordant addition within the street scene. Overall, the development would fail to preserve the character and appearance of the Conservation Area causing less than substantial harm to the conservation area without any notable public benefit. Therefore, the proposal would be contrary to PDECHHODB (ODB) 27249/APP/2026/500 Policy D3 of The London Plan (2021), Policy BE1 of the Hillingdon Local Plan: Part One - Strategic Policies and Policies DMHB 4, DMHB11, DMHB12 and DMHD1 of the Hillingdon Local Plan - Part Two (2020).

From the council's decision notice.
