Structural engineers in London

Structural engineering, Building Control calculations and surveys for homes, developments and commercial projects across London, delivered remotely nationwide with site visits arranged throughout the capital.

Structural engineering across London

London packs an enormous range of building types into a small area, from Georgian and early Victorian terraces in Islington, Camden and Hackney, to grand stucco-fronted houses in Kensington and Chelsea, mansion blocks in Maida Vale, and the interwar and post-war stock spreading out through the outer boroughs of Ealing, Croydon and Bromley. Each raises its own structural questions, whether that is removing a load-bearing spine wall in a narrow terrace, forming a loft in a converted Victorian house, or digging out a basement below an existing property in the inner boroughs.

We cover the full structural remit for London projects: Eurocode calculations and drawings for rear and side-return extensions, loft conversions, wall removals and basement works, structural surveys and inspection reports, and design for new build and commercial fit-out. Desktop calculations and reports are delivered anywhere in London quickly, and where a survey, a party wall inspection or a movement assessment is needed we arrange it across the capital and the surrounding Home Counties.

London Clay and what it means for foundations

Much of London sits on London Clay, a stiff, over-consolidated clay that is a reliable bearing stratum but is also strongly shrinkable. It moves with seasonal moisture change and is very sensitive to trees, so foundations near mature planting often need to go deeper than the standard minimum, and clay heave has to be considered where trees have been removed. In the Thames valley and along the river terraces the clay is overlain by sands and gravels, and in low-lying areas near the river you can meet made ground and softer alluvial deposits that call for engineered or piled solutions.

We design to the ground rather than to a default depth, specifying strip, trench-fill, raft or piled foundations to suit the plot, and checking foundation depth against the shrinkage and heave risk set out in the NHBC guidance. For basement projects, which are common across the inner boroughs, we assess retaining pressures, underpinning sequences and the effect on neighbouring structures, and coordinate the design with party wall requirements.

How we work with London clients

Most structural work is produced from your architect's drawings and survey information, so a service-area model suits London well. We turn desktop calculations and reports around quickly, and we coordinate with your architect, contractor and the borough Building Control team or an approved inspector so the structure and the design agree before work is priced and started on a tight urban site.

Where a physical inspection is needed, for a survey, a check of existing structure, crack monitoring or a basement feasibility review, we arrange a visit across London. Every output is tied to the Eurocodes and Approved Document A, backed by professional indemnity cover, and we work for clients across the UK, where the same Eurocode basis applies.

Questions

Common questions

Do you cover the whole of London?

Yes. We provide structural calculations, surveys and design across all London boroughs, inner and outer. Desktop work is delivered remotely, and site visits, including party wall and basement inspections, are arranged across the capital.

Do you need to visit my property in London?

Not always. Calculations for extensions, lofts and wall removals are usually produced from drawings and photos. A visit is arranged where a survey, movement assessment, basement feasibility check or inspection of existing structure is needed.

Can you handle basement and underpinning projects?

Yes. We design basements and underpinning schemes common across inner London, assessing retaining pressures, ground conditions and the effect on neighbouring structures, and we coordinate the design with party wall requirements.

Can you provide calculations for Building Control in London?

Yes. We prepare Eurocode structural calculations and drawings ready for your borough Building Control team or an approved inspector, written to demonstrate compliance with Approved Document A and to be followed on site.
