Homes in Bromley and what suits them

Bromley's appraisals describe Victorian semi-detached houses on North Street, West Street and College Road, and modest artisan terraces and semis in Shortlands Village. Semi-detached houses often suit a hip-to-gable loft and a full-width rear extension; terraces suit rear dormers.

Planning in Bromley

Bromley is in the London Borough of Bromley, which has 47 conservation areas, including Bromley Town Centre and Shortlands Village.
Bromley's guidance for conservation areas such as Shortlands Village says dormers are not automatically acceptable, and where allowed should sit below the ridgeline, with rooflights flush and preferably at the rear.
Article 4 directions remove the right to add extra storeys to houses (permitted development Class AA) in Areas of Special Residential Character such as Bickley, Bromley Common, Park Langley and Petts Wood. In the Chislehurst Road conservation area in Petts Wood, roof alterations also need planning permission.
Outside these areas, many rear dormers and single-storey rear extensions can be built under permitted development.

How we work in Bromley

Our in-house team does the measured survey, drawings and the planning or permitted-development application through Plan It, then manages the build with a single project lead. Party wall agreements are handled through our partner surveyors. Typical build times: rear dormer 10–12 weeks, L-shaped dormer 12–14 weeks, mansard 12–16 weeks, rear extension 12–16 weeks.

Bromley: questions homeowners ask

Do I need planning permission for a loft conversion in Bromley?

Outside conservation areas and Article 4 areas, many rear dormers are permitted development. In Bromley's 47 conservation areas, and in places like the Chislehurst Road area, roof changes need planning permission.

Which council handles planning in Bromley?

The London Borough of Bromley.

How long does a loft conversion or extension take in Bromley?

Most of our lofts take 10–16 weeks on site and most rear extensions 12–16 weeks, depending on the design. If you need planning permission, allow around 8 weeks for the council's decision on a householder application, plus time to prepare the drawings.

Can you design it as well as build it?

Yes. Our Plan It service covers the measured survey, drawings and the planning or permitted-development application. You can stop there, or carry straight on to the build with the same team.
