Planning and building regulation drawings in Kilburn (NW6)

NW6 is split between two councils, and the three areas inside it each ask something different of a homeowner. Kilburn is mostly late-Victorian terraces and semi-detached houses on the streets off the High Road and Willesden Lane, many converted into flats, with Edwardian and interwar stock toward Salusbury Road. West Hampstead has dense red-brick Victorian and Edwardian terraces and mansion blocks around its stations; its streets include Fordwych Road, Sumatra Road and Dennington Park Road. Queen's Park is dominated by the uniform Artizans' cottages of the Queen's Park Estate and the late-Victorian terraces around them; Milman Road and Kingswood Avenue are among its streets.

That variety produces very different briefs. In Queen's Park the building lines and detailing are shared from house to house, so owners tend to work at the back and in the roof, keeping the street front as it is. The gardens are modest and the cottages are small, which limits rear depth. West Hampstead is heavily subdivided, so a lot of projects are flat alterations where leasehold consent, party wall awards and means of escape run alongside the planning drawings.

Kilburn sits in the middle. Where a house is whole, side-return and rear work may be possible, but North Kilburn is a conservation area with its own Article 4 direction, and the HMO direction means turning a house into shared occupation needs permission. Because NW6 sits under more than one authority, the first step on any property is to work out which council and which designations apply, then draw to that council's requirements rather than assuming a single local rulebook.

Planning in Kilburn: what to know before you apply

Brent and Camden each handle householder applications in their own way in NW6, so the council for your street matters. In Brent, design is controlled in conservation areas such as Queen's Park, and on the Queens Park Estate cottages there is a strong presumption against front and roof-slope alterations visible from the street. North Kilburn has an Article 4 direction removing permitted development, and Brent also withdraws the right to convert a house to a small HMO. In West Hampstead, the West End Green and Priory Road designations govern red-brick frontages and rooflines, and flats carry no permitted development rights. We check the council, the designation and the ownership structure of your property before choosing a route.

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

Kilburn (NW6) — FAQs

Can I extend a Queen's Park Estate cottage at the back?+
Within limits. The estate's uniform frontages and roof slopes are protected, so the work focuses on the rear, and the small gardens restrict how far an extension can project. We establish whether permitted development or a full application is the right route.
Does turning my Kilburn house into a shared house need planning permission?+
Yes. Brent has removed the permitted right to change a house into a small house in multiple occupation, so an application is needed. North Kilburn also has its own Article 4 direction, and we check whether it touches your street.
