Planning and building regulation drawings in West Wickham (BR4)

The plots shape what can be built. Deep rear gardens, set-back front gardens and regular gaps between pairs of houses can leave room for a rear extension, a loft conversion or both. Because the streets follow a consistent rhythm, though, the council reads a proposal against the street rather than against a single house. A side extension that closes the gap between a semi-detached pair can harm the spaciousness the suburb is known for, and a front-facing dormer is judged for its effect on a uniform roofscape.

Materials matter too. A rear or side extension that matches the original facing brick, render, tile-hanging and roof tile reads as part of the house, while a mismatched one reads as a later addition. Neighbour amenity sets the practical limit on larger single-storey schemes, with overshadowing, overlooking and the party wall all in play. We start each job by checking the street, the house type and any designation on the address, then draw to the route that fits.

Planning in West Wickham: what to know before you apply

We know of no conservation area in West Wickham and have found no area-specific Article 4 direction, so many houses keep ordinary householder permitted development, subject to the limits on depth, height and roof form. Bromley still applies its householder design guidance when an application is needed, and it expects extensions to respect the settled building lines and gaps of the street. Properties that have been converted to flats have no householder permitted development rights at all. If an address does turn out to lie in a conservation area, roof enlargements, side extensions and rear extensions of more than one storey are not permitted development. An application needs an ownership certificate or notice, not the freeholder's consent. We confirm designations with the council before advising.

Applications are decided by London Borough of Bromley — its planning pages.
