Longthornton Road Merton SW16 5QD
The proposed development comprises the conversion of an existing four-bedroom single-occupancy dwellinghouse (Use Class C3) into two self-contained residential flats, also within Use Class C3. One flat will comprise three bedrooms and the second flat will comprise four bedrooms. The existing rear garden will be subdivided to provide private amenity space for each flat, with independent access to both garden areas. A small single-storey rear extension will be removed to enable independent access to the rear garden for the upper flat. Cycle and refuse storage will be provided to the front of the property. No additional extensions or external alterations are proposed. The existing building envelope will be retained, and all fenestration will remain unchanged.
