Flat 5, 77 Cadogan Square, London, SW1X 0DY
Formation of mansard roof above the rear portion of No. 75 to extend the existing fifth floor apartment at Nos. 75-77 Cadogan Square, together with the installation of flat roofed dormer windows, rooflights and a concealed roof terrace, and internal alterations including the insertion of a staircase to create a duplex apartment
The proposed mansard extension and terrace would result in loss of historic fabric of the building and features of historic interest and would cause less than substantial harm to the significance and special interest to the listed building. Given that insufficient heritage or other public benefits have been provided to outweigh the harm, the proposal would therefore harm the significance and group value as such would fail to comply with the Development Plan, specifically Policies CD3 and CD5 of the Local Plan 2024.
The proposed mansard extension and roof terrace would detract from the original character of the property, roof profile and surrounding area. As such the proposal is considered an incongruous addition which would cause harm to the Hans Town Conservation Area, contrary to the Development Plan, specifically Policies CD1, CD2, CD4, CD12 and CD15 of the Local Plan 2024.
