Typical extension price
A 25 m² single-storey rear extension in Manchester typically runs £50,000-£74,000 (standard to premium, 2026). Loft conversions in Chorlton/Didsbury Edwardian semis run £45,000-£68,000.
Building Control
Manchester Building Control is the council's in-house service with 3-4 day inspection lead time. Heavy private-AI competition (LABC, MD, Stroma) across M19, M20, M21 and Didsbury.
Conservation & Article 4
Manchester has 37 conservation areas including Didsbury Village, Chorlton Green, Victoria Park and Whalley Range. Article 4 directions covering external materials apply across most of Didsbury Village and Victoria Park.
Local quirks that move the price
Coal Authority searches are mandatory across much of south Manchester (M19, M21, M22) — historic shallow workings can add £3-8k for foundation upgrades. High water table in Withington/Chorlton requires perimeter drainage on most rear extensions. Tight Edwardian back-alley access often forces hand-dig and adds 1-2 weeks to programme.
