Planning and building regulation drawings in Willesden (NW10)

NW10 covers three areas whose housing runs from Victorian terraces to interwar suburbia. Willesden has late-Victorian and Edwardian terraces and bay-fronted houses around Willesden High Road and Walm Lane, with mansion blocks on the main roads and some interwar and post-war infill toward Harlesden and Kensal. Harlesden is dense Victorian terracing radiating from the High Street and the Jubilee Clock, with a large share already converted to flats. Neasden is mostly interwar semi-detached and terraced houses with reasonable gardens, mixed with post-war estates and a small surviving village core.

That spread decides the typical project. In Neasden, family rear, side and loft extensions are the projects the interwar semi suits, though layout and amenity standards shape what can be achieved on estate housing. In Willesden, rear and loft schemes on the late-Victorian and Edwardian terraces and bay-fronted houses are drawn knowing that the council assesses dormers and elevation changes against the established grain of the street. In Harlesden, where so many houses are already flats, work is as likely to be a conversion or layout question as an extension, and amenity, refuse and layout all come into play.

Designations add detail. The Willesden Green conservation area was extended in 2024 to take in several streets including Chatsworth Road and Dean Road, so addresses that were outside it before may now be inside. Kensal Rise covers streets to the south of the district, Harlesden controls frontages and materials around the High Street and the Jubilee Clock, and Neasden Village protects the small historic core around the green; Old Oak Lane and Homestead Park are further conservation areas. We therefore check the current boundary for your street before drawing, rather than relying on what neighbours remember.

Planning in Willesden: what to know before you apply

Brent assesses householder applications in NW10 against the character of the street. Where a conservation area applies, the council watches frontages, materials and rooflines, and dormers or front-elevation changes are closely assessed on the Victorian terraces. Brent also removes permitted development for the change of a house to a small house in multiple occupation across the borough, so a Willesden change to shared occupation needs a full application. Where houses have already been split into flats, there are no householder permitted development rights, and consideration of amenity, refuse and layout comes in. We check conservation boundaries, directions and the status of the building before preparing drawings for validation.

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

  • A single-storey rear extension up to 4 m deep on a detached house, or 3 m on any other house, is Class A permitted development subject to the height and materials conditions.
  • An Article 4 direction applies here and may withdraw this freedom — the schedule must be checked before relying on it.
  • One or more constraints are unknown — we check the council's registers as part of the free appraisal.
  • Where permitted development applies, a lawful development certificate proves it for lenders and buyers.

FAQ

Willesden (NW10) — FAQs

Has the Willesden Green conservation area changed recently?+
Yes. It was extended in 2024 to take in more streets, among them Chatsworth Road and Dean Road. If you live nearby, we check whether your address is now inside before advising on a route.
Can I build a loft extension on an interwar semi in Neasden?+
It is one of the common projects there: rear, side and hip-to-gable loft work suits the interwar semi. Whether permitted development covers it depends on the house and any nearby designation such as Neasden Village. We check this before drawing and prepare the application if permission is needed.
