Why it was refused

  1. Because of the proposed design and positioning of the replacement ('typical') sash windows, with the full box frames set exposed within the masonry openings rather than recessed behind the reveals, the submitted details would result in uncharacteristically deep and visually prominent window frames and a reduced glazing area, which fail to reflect the traditional proportions and arrangement of the existing sash windows. This would harm the appearance of the building and would fail to preserve or enhance the character and appearance of the Knightsbridge Conservation Area. The proposal is therefore contrary to Policies 42, 44 and 45 of the Westminster City Plan (January 2026).

From the council's decision notice.
