Does Brent planning policy restrict a rear dormer?

Brent conservation designations: there are 22 across Brent Council, Harlesden, Sudbury Court, Queen's Park among them. Designation costs a Brent owner the permitted-development route: a rear dormer then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Sudbury Court is the Brent designation that most often changes a rear dormer design.

What Article 4 removes near Brent: Article 4 for HMO conversions in specific streets around Wembley and Harlesden. Before pricing a rear dormer we check whether the NW2 address is inside the mapped area, because Brent Council draws the Brent boundary street by street rather than across the whole of Brent.

The building fabric around Brent: Edwardian villas in Queen's Park and Mapesbury; Victorian terraces in Kilburn and Harlesden; 1930s semi-detached in Wembley; post-war tower blocks in Church End. Highly diverse borough; Queen's Park and Mapesbury are heritage-controlled; Wembley is a major regeneration hub. A rear dormer in Brent is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Brent Council.

Who decides a rear dormer on the edge of Brent?

• Harrow — the Harrow boundary runs against Brent, so a rear dormer a street from Brent is decided by Harrow Council instead. Harrow runs 29 conservation areas across HA1 and its neighbours, which is why rear dormers priced for Brent are re-checked against Harrow policy whenever the Brent address sits on that edge.
• Barnet — cross the Brent boundary and Barnet Council takes the rear dormer instead, applying 20 conservation areas of its own around N2. We re-price rear dormers at the Brent edge because Barnet policy and Brent policy rarely align on rear dormer depth.
• Camden — adjoining Brent, with 40 conservation areas centred on NW1. A rear dormer on the far side of the Brent line is determined by Camden Council, so the Brent quote for rear dormers is checked against Camden guidance before it is issued.
