Why it was refused

  1. The proposed development by reason of its bulk, size, massing, design and crown roof would fail to read as subordinate to the host dwelling or respect its architectural integrity, appearing as an incongruous and visually dominant addition to the streetscene, failing to respond to the establish context and thereby harming the character and appearance of the area, all contrary to Policy D3 of the London Plan (2021) and Policies DMHB 11 and DMHD 1 of the Hillingdon Local Plan Part Two (2020).

From the council's decision notice.
