Why it was refused
Reason
As stated on the decision notice
1
Your drawings do not include enough details of the age and condition of the existing windows and
glazed doors 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)
2
Because of their detailed design, the proposed replacement windows and glazed doors 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)
