Scheme description

Replacement of single-glazed windows on first and second floor of front elevation with new slimline double glazed timber sash windows.

Why it was refused
Reason 1

Your drawings do not include enough details of the existing adjacent historic windows (including visible framing dimensions and framing and glazing bar profiles) for us to assess how your plans would affect the building and the Belgravia Conservation Area. We believe that the work could fail to maintain or improve (preserve or enhance) the character and appearance of the building and the conservation area. This would not meet Policies 42 and 44 of the City Plan 2019 - 2040 (January 2026). (X22AE)

Reason 2

Because of their detailed design, the proposed replacement windows would harm the architectural and historic interest of this grade II listed building. They would also fail to maintain or improve (preserve or enhance) the character and appearance of the Belgravia Conservation Area. This would not meet Policies 42, 44 and 45 of the City Plan 2019 - 2040 (January 2026). (X17AE)
