Luxury Builders

Prime residential construction in Bromley & Chislehurst

Crown Building works at the top of the London market, and Bromley & Chislehurst is core territory for our team. The projects in our published case studies were delivered under exactly the constraints that define this part of London. Protected fabric, exacting consents, discreet site conduct and clients who judge the result at touching distance.

We do not operate at volume. We compete on execution. Meticulous programming, a trusted specialist supply chain and senior management present on site throughout are the baseline for every commission we accept in Bromley & Chislehurst. The standard does not change with the scale of the project.

What we build in Bromley & Chislehurst

Our residential work spans the full scope of high end building. We deliver architecturally distinctive new build homes, private residence refurbishments and structural reconfigurations, single and multistorey extensions, basement excavations, listed and period property works, and the bespoke joinery and interiors that define a finished home. Each project is delivered as design and build or contractor only, with Crown appointed as your prime residential main contractor, and transparent, itemised pricing from the outset. Commercial occupiers are served by the same teams through our commercial fit out division, and clinical and wellness premises through our healthcare and specialist environments team.

Chislehurst's houses around the commons and Camden Park, Bickley's private roads and the Sundridge Park estate carry substantial Victorian, Edwardian and interwar homes on generous plots: the classic canvas for private residence transformation: structural reconfiguration, large rear extensions, basements and complete specification upgrades. Conservation designations cover much of Chislehurst, and the best plots increasingly attract replacement new builds. The brief is identical to our north of London home turf; only the postcode differs.

Areas we serve

We work across Bromley and Chislehurst: the commons, Camden Park, Bickley, Sundridge Park and Petts Wood, plus Keston, Hayes and Orpington's borders. You can see our full coverage, London within the M25 and a fifteen mile radius of our Watford headquarters, on our areas we cover page.

Bromley has no basement policy at all

This is a verified negative rather than an oversight in our research, and it is unusual enough to state plainly. The Bromley Local Plan, adopted on 16 January 2019, contains no reference to basements whatsoever. The borough's Urban Design Guide mentions them only in relation to car parking.

A basement in Chislehurst is therefore assessed under general design policy, the residential extensions policy, heritage policy, flood risk and national planning policy, rather than against any local numeric standard. There is no garden percentage, no storey cap and no soil depth requirement to design to, and anyone quoting such figures for Bromley is applying another borough's rules. In practice that gives more room to argue a scheme on its merits, and correspondingly more weight falls on the quality of the design and the supporting assessment.

The only numeric householder standard in the plan worth knowing is Policy 8 on side space: for proposals of two or more storeys, a minimum of one metre must be retained from the side boundary for the full height and length of the development.

Chislehurst's Article 4 directions and Areas of Special Residential Character

Bromley has forty seven conservation areas, and Chislehurst carries two: the Chislehurst conservation area and a separate Chislehurst Road conservation area, the latter with an appraisal and management plan adopted on 25 June 2025.

An Article 4 Direction confirmed on 24 June 2022 and effective from 19 July 2022 removes permitted development rights under Part 1 Class C, covering roof alterations, in the Chislehurst Road conservation area. Bromley also uses Article 4 directions to protect designated Areas of Special Residential Character, and the Marlings Park Estate in Chislehurst is one of them. That designation is not a conservation area but it functions similarly in restricting what can be done without permission, and it is easy to miss because it does not appear on a conservation area map.

Half the borough is Green Belt, and the Commons have their own Act

Bromley is the largest London borough at around a hundred and fifty square kilometres, and government figures for March 2025 record 7,660 hectares of its 15,010 hectares as Green Belt, just over half. Scadbury Park, immediately north east of Chislehurst, is confirmed Green Belt, and Local Green Space designations in Chislehurst include Bull Lane Allotments, the Chislehurst and Walden recreation grounds, Whytes Wood and Walden Woods.

Chislehurst Commons add a further layer that has nothing to do with the planning system. Around a hundred and ninety acres are governed by the Metropolitan Commons (Chislehurst and St Paul's Cray) Supplemental Act of 1888, which remains in force with an attached scheme of management administered by the Commons Trustees. Where a property adjoins or takes access across the Commons, that regime is a separate consideration from planning permission, and it is worth establishing the position early rather than discovering it when access for plant is needed.
