Construction Services in Bromley

Bromley is London's largest borough by area and one of its most suburban — a district of tree-lined streets, detached houses, and generous gardens. The borough stretches from the suburban centres of Bromley, Beckenham, and Petts Wood to the rural fringes of Biggin Hill and Downe, creating a diverse construction market.

Home extensions dominate Bromley's construction demand. The borough's predominantly detached and semi-detached housing stock sits on plots large enough for ambitious builds — double-storey extensions, wrap-around ground-floor expansions, and garage conversions. Families choose to extend rather than move, investing heavily in properties located near the borough's outstanding schools and green spaces.

We deliver construction projects across the full breadth of Bromley — from high-specification kitchen extensions in Chislehurst to practical loft conversions in Penge.

Bromley Housing Stock

1930s detached and semi-detached houses, Victorian villas in Beckenham and Bromley, Edwardian housing in Chislehurst, 1960s–1970s detached houses in Petts Wood and Orpington, and bungalows in outlying areas.

Planning in Bromley

Bromley Council is generally supportive of proportionate residential extensions, with most standard projects progressing through permitted development or straightforward householder applications. The borough has several conservation areas — Chislehurst, Shortlands, Bromley Town Centre, and parts of Beckenham — where additional planning controls apply.

Bromley's extensive Green Belt, covering the southern and eastern parts of the borough, restricts development in areas like Downe, Farnborough, and Green Street Green. Properties within or adjacent to the Green Belt face limitations on extension size and new development potential.

FAQs — Construction in Bromley

How much does a double-storey extension cost in Bromley?

Double-storey extensions in Bromley typically cost £85,000–£145,000 depending on width, specification, and ground conditions. Bromley's generous plots often allow wide extensions that maximise the return on investment.

Do I need planning permission to extend in Chislehurst?

Parts of Chislehurst are within a conservation area, which removes many permitted development rights. Properties in these areas require planning permission for extensions, dormers, and significant external alterations. We confirm your property's status and manage any applications required.

Can I build in Bromley's Green Belt?

The southern part of the borough is Green Belt. Extensions must be proportionate, and new development is generally restricted. We assess Green Belt implications during our initial survey and advise on realistic options.

How long does a rear extension take in Bromley?

A standard single-storey rear extension takes 10–14 weeks from breaking ground. Bromley's predominantly clay soil can extend the foundation phase by 1–2 weeks compared to gravel sites. We account for this in every project timeline.
