The proposed roof terrace and mansard roof to the side wing by reason of the overall bulk, siting, and design, would fail to read as subordinate additions to the property and fails to respond to the existing character and context of the host building and surrounding context. As a result, the proposal fails to preserve or enhance the character and appearance of the conservation area and would result in less than substantial harm to this designated heritage asset. The harm would not be outweighed by any public benefits and therefore, the proposal would conflict with policies CL1, CL2, CL3, CL6, CL8, CL9 and CL11 of the 2019 Local Plan.
