Planning permission drawings, loft conversions, and extensions for Willesden's Victorian and Edwardian terraces. MCIAT chartered, fixed fees, Brent planning expertise built in.
Willesden spans the NW2 and NW10 postcodes in the London Borough of Brent. The neighbourhood's residential streets — from the grand Edwardian avenues of Mapesbury to the compact Victorian terraces of Willesden Junction — offer diverse opportunities for residential extension and improvement.
Mapesbury Conservation Area: The Mapesbury Conservation Area covers one of north-west London's finest collections of Edwardian houses. Article 4 Directions restrict permitted development rights, meaning planning permission is required for most external alterations including dormer conversions, window replacements, and front boundary changes. Our MCIAT-chartered team specialises in conservation-sensitive applications that satisfy Brent's planning officers.
Victorian terraces: Willesden's Victorian terraces outside the conservation area are prime candidates for rear dormers, single-storey rear extensions, and side-return infills under permitted development. We confirm PD eligibility and prepare building regulations drawings.
Flat conversions: Many Willesden houses have been converted to flats. Further subdivision or reconversion projects require planning permission and must comply with Brent's housing standards. We prepare the necessary applications.
Brent Design Guide: Brent's Design Guide SPD provides specific guidance on extension design. We design schemes that comply with this guidance, improving approval prospects.

Dormer conversions, window replacements, and front alterations typically require planning permission. We prepare conservation-sensitive applications.
Outside the Mapesbury Conservation Area, rear dormers under permitted development are straightforward. Within the conservation area, planning permission is required. We survey your roof and advise on the best approach.
