Foundations in Bromley
Foundations are the below-ground concrete structure that transfers the load of a building safely into the ground, with the type — strip, trench-fill or raft — and depth determined by ground conditions, nearby trees and the load of the structure above.
In Bromley, that covers Beckenham, Orpington, West Wickham, Chislehurst, Petts Wood, Hayes, Bickley. Bromley is one of the greenest London boroughs, with a historic High Street and residential areas ranging from Beckenham and Orpington's Victorian and interwar housing to the more rural character around Chislehurst and Hayes, close to the Kent border and within easy reach of our Sevenoaks and Tunbridge Wells teams.

Property styles in Bromley
Bromley's housing stock includes Victorian and Edwardian terraces and villas near the town centre and in Beckenham, substantial interwar detached and semi-detached houses across Orpington, Petts Wood and Bickley, and larger period properties around Chislehurst and Hayes, many on generous plots suited to rear and double-storey extensions.
Planning considerations
Bromley Council (London Borough of Bromley) is the local planning authority. Chislehurst and parts of Beckenham and Hayes are conservation areas, and much of the borough's southern and eastern edge is designated Metropolitan Green Belt, which restricts new buildings and substantial additions beyond normal permitted development limits.

FAQs
Foundations in Bromley: FAQs
Do you provide foundations across all of Bromley?
Yes, we cover the BR1, BR2, BR3, BR4, BR5, BR6 and BR7 postcode areas in full, including Beckenham, Orpington, West Wickham, Chislehurst, Petts Wood, Hayes, Bickley.
How deep do foundations need to be?
Depth depends on ground conditions, the load of the structure and proximity to trees or drains — a straightforward strip foundation might be around 1m deep, but clay soils near mature trees can require significantly deeper trench-fill foundations. This is confirmed by site investigation and agreed with Building Control.
Does Building Control need to inspect the foundations before concrete is poured?
Yes. An open-trench inspection is a standard Building Control stage, carried out once excavation is complete and before concrete is poured, to confirm the ground conditions and depth match what was approved.
Do you work across all of the Bromley postcode areas?
Yes, we cover BR1 to BR7, including Bromley town centre, Beckenham, Orpington, West Wickham, Chislehurst, Petts Wood and Hayes.
