14, Haslemere Avenue, London, SW18 4RP
Proposal
Erection of a single-storey outbuilding within the rear garden to provide a home office and ancillary storage/workshop use. The proposed structure comprises a simple, modestly scaled form with a shallow mono-pitched roof, stepping down towards the rear boundary to ensure a subservient relationship to the host dwelling and to respect the surrounding garden setting. The design incorporates rooflights and glazed openings to provide adequate levels of natural daylight and ventilation, and to maintain visual connectivity with the garden.
