Dormer Loft Conversion in NW London

Select Your Area

We provide dormer loft conversion across NW London's premier neighbourhoods. Each area has specific planning rules and property characteristics — select yours for tailored information.

How It Works

1. 1

   Initial Survey and Roof Assessment

   We inspect the existing roof structure — rafters, ridge beam, hips if present, and floor joists — to assess dormer viability and headroom. We take precise measurements, identify the proposed staircase route from the floor below, and confirm the structural approach before producing any drawings.

2. 2

   Planning Assessment and Pre-Application Advice

   We establish whether the property retains permitted development rights for a rear dormer or whether planning permission is required due to Article 4, conservation area status, or listed building constraints. In Article 4 areas we book pre-application advice with the conservation officer before committing to a design direction.

3. 3

   Design, Planning Application, and Party Wall Notices

   Architectural drawings are prepared for planning submission where required. Simultaneously, Party Wall Act notices are served on all adjoining owners. In conservation areas the drawings will address roofscape character, rear elevation materials, and window design in response to officer guidance.
