Planning in Kingston upon Thames
Checked October 2026. Planning policy changes, so we confirm the position for your address before you commit.
Single-storey rear extensions should generally be no more than 3 to 3.5m deep, and no more than 3m high with a flat roof or 4m with a pitched roof (Residential Design SPD, 2013). The guidance is over ten years old, so its weight should be checked case by case.
SourceSingle-storey side extensions should be no wider than half the original house, set in at least 250mm from the boundary and set back at least 500mm from the front wall (Residential Design SPD, 2013).
