Structural Calculations in Reigate
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 Reigate, that covers Woodhatch, Reigate Heath, Meadvale, Wray Park, Colley. Reigate sits at the foot of the North Downs, with a historic town centre and a number of well-established residential areas featuring substantial Victorian, Edwardian and interwar houses. Its position near the Surrey Hills National Landscape (formerly AONB) shapes planning policy for parts of the borough.

Property styles in Reigate
Reigate has a strong stock of larger detached and semi-detached Victorian and Edwardian houses, along with mock-Tudor interwar properties, many of which suit generously proportioned rear and wraparound extensions or double-storey additions.
Planning considerations
Reigate & Banstead Borough Council is the local planning authority. The historic town centre is a conservation area, and parts of the borough fall within the Surrey Hills National Landscape (National Landscape, formerly AONB), which brings additional design and landscape considerations for extensions and new structures.
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 Reigate: FAQs
Do you provide structural calculations across all of Reigate?
Yes, we cover the RH2 postcode area in full, including Woodhatch, Reigate Heath, Meadvale, Wray Park, Colley.
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.
Does the Surrey Hills National Landscape designation affect extensions in Reigate?
For properties within the designated area, additional weight is given to landscape character and visual impact in planning decisions. We check whether your property falls within the boundary during feasibility.
