Working in Kilburn
Across NW2, NW3, NW6, NW8, NW11, W9, we can visit, measure and advise. Neighbouring towns we cover include Cricklewood (1 mile), Golders Green (2 miles), Chalk Farm (2 miles), Camden Town (2 miles).
Borehamwood, in Hertfordshire, is roughly 8 miles from Kilburn and also on our list. London's housing is dominated by Victorian and Edwardian terraces, many with a rear outrigger and a side return, and 1930s semis in the outer boroughs. Conservation areas are common, so the planning check comes first.
Do I need planning permission in Kilburn?
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
