Structural Calculations in Bromley
Structural calculations are the engineering sign-off needed whenever a project alters or removes a load-bearing element — a steel beam over a knocked-through wall, a new foundation for an extension, or a strengthened floor for a loft conversion — set out in a structural drawing and calculation pack that Building Control checks the work against.
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.
How it works
Our structural calculations process
- 01
Site survey
Assessing the existing structure — what it is, what condition it's in, and what the proposed works need it to do.
- 02
Structural design
Sizing the beams, foundations or floor strengthening needed, coordinated with the architectural drawings where we're producing both.
- 03
Calculations pack
Preparing the formal calculation pack and structural drawings in the format Building Control and the wider design team need.
- 04
Building Control liaison
Submitting calculations to Building Control and handling any follow-up queries through to approval.
- 05
Construction support
Available through the build for any site queries as the structural work is carried out.

FAQs
Structural Calculations in Bromley: FAQs
Do you provide structural calculations 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.
Do I need structural calculations for a loft conversion?
Almost always — the existing floor typically needs strengthening to take habitable-room loading, and any new stair opening or dormer usually needs its own structural design. Building Control will check the work against a calculation pack as part of sign-off.
Can you provide calculations for a beam I've already had designed elsewhere?
We generally produce calculations as part of a coherent structural design for the whole project, but get in touch with what you have and we'll advise whether we can work from it or whether it needs revisiting.
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.
