Does Ealing planning policy restrict a rear dormer?

Ealing conservation designations: there are 30 across Ealing Council, Acton Green, Hanwell, Ealing Broadway among them. Designation costs a Ealing 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. Ealing Broadway is the Ealing designation that most often changes a rear dormer design.

What Article 4 removes near Ealing: Article 4 for HMOs in specific streets in Acton, Ealing and Southall. Before pricing a rear dormer we check whether the W3 address is inside the mapped area, because Ealing Council draws the Ealing boundary street by street rather than across the whole of Ealing.

The building fabric around Ealing: Victorian and Edwardian villas in Ealing central; 1930s semi-detached in Northolt and Hanwell; mansion blocks along main roads; Bedford Park is a listed Arts & Crafts garden suburb. Leafy outer-west London; Bedford Park conservation area has strict heritage controls; rest of borough generally permissive. A rear dormer in Ealing 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 Ealing Council.
