Building work in Beckenham: area guide

This is our area guide to building work in Beckenham (BR3, Bromley): the housing, the council rules that apply (Bromley Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Beckenham.

Beckenham does not have a single housing type, and pricing work here starts by settling which you own. On VOA figures, most homes in BR3 are flats, where the freeholder's licence and the floor over the flat below come before any wall is touched. Most of BR3 was built after 1945, but the older houses split two ways: Edwardian villas with solid brick walls, wide halls and heavy timber floors in the older streets near Kelsey Park, and interwar semis with cavity walls, hipped roofs and remarkably regular spans in the estates towards Beckenham Place Park. The two need different methods for the same load-bearing wall removal job.

Beckenham has about 13,510 homes on the Council Tax list: 24% pre-1919, 10% interwar and 65% post-war, with flats making up 62% and houses 38%. VOA Council Tax stock of properties, March 2025, for New Beckenham, Beckenham East & Kelsey Park and Clock House & Cator Park. Counts rounded by the VOA.

Villa or semi: two ways to cut the same opening

An Edwardian villa is solid masonry, usually a brick and a half thick, with suspended timber floors, lath and plaster and a cut roof carried on purlins. There is no cavity to protect and no wall ties, but the brick is softer than modern work, so the bearings for any new beam are exposed and inspected rather than assumed sound. Where the load is heavy, needling through to firm masonry comes before the opening is cut. That makes it RSJ installation led by the bearing: the engineer we appoint specifies the padstone and bearing length, and we build precisely to it.

An interwar semi is a different animal: two leaves of brick with a cavity between them, tied together, sometimes with insulation retrofitted into that gap, and lintels of concrete or steel already over the openings. Cutting into it correctly means closing the cavity at the new reveal, installing a cavity tray and weeps where water can now track across, and reinstating disturbed insulation. Skip that and you get a damp patch on the inside face a winter later, far more expensive to chase than to detail properly. Open-plan conversions on a semi carry the cavity detail.

Survey checks in BR3 that decide which job it is

A survey here is a list of specific checks rather than a walk round. In the interwar stock: wall tie condition, whether the bay has a proper lintel or relies on a timber one, and whether the hip has spread where a previous owner took out roof timbers for storage. In the older villas: the state of the bearings, the direction the joists run, past openings formed without support, and plaster where movement has been decorated over. A spread hip or a timber bay lintel is structural alteration work before any room is fitted. Everything we find is photographed and given to the engineer.

A structural engineer designs any beam and its bearings, we prop on spread sole plates, cut in stages and transfer the load before striking anything, and building control applications and inspections are coordinated with Bromley Council. On a semi, the beam frequently bears into the wall shared with next door, which brings the Party Wall etc. Act 1996 into play, and the duty to serve notice is yours as the building owner. Installations we carry out are covered by a five year guarantee.
