Structural Calculations in Brighton and Hove
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 Brighton and Hove, that covers Kemp Town, Hove, Preston Park, Hanover, Seven Dials, Fiveways, Patcham, Portslade. Brighton and Hove is known for its Regency architecture, extensive Victorian terraced housing, and later 20th-century development, all within a compact coastal city where many properties are in conservation areas and a significant number are listed.

Property styles in Brighton and Hove
Regency squares and terraces are concentrated around Brunswick, Kemp Town and the seafront, with dense Victorian terraced housing across much of the wider city, and later suburban housing further from the centre. Basement conversions, loft conversions and rear extensions are common project types on the terraced stock, subject to conservation area and party wall considerations.
Planning considerations
Brighton & Hove City Council is the local planning authority. The city has one of the highest concentrations of conservation areas of any local authority in the South East, and many properties are listed, particularly in the Regency squares. Basement work also requires careful consideration of structural and drainage issues in a dense urban setting.
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 Brighton and Hove: FAQs
Do you provide structural calculations across all of Brighton and Hove?
Yes, we cover the BN1, BN2 and BN3 postcode areas in full, including Kemp Town, Hove, Preston Park, Hanover, Seven Dials, Fiveways, Patcham, Portslade.
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.
Can I extend a listed Regency property in Brighton?
Alterations to listed buildings require listed building consent in addition to any planning permission, and the historic character of Regency terraces means proposals are considered carefully. We assess feasibility on a case-by-case basis.
