Structural Engineers in London
Structural calculations, drawings and practical engineering support across London — from townhouse refurbishments in Central London to loft conversions and extensions in the outer boroughs.
London projects move faster when we know the basics: borough, full postcode, property type (terrace / semi / flat), scope of works, and whether the wall supports floors/roof. Photos + drawings help.
We cover London-wide. Common areas include Westminster, Camden, Islington, Kensington & Chelsea, Hammersmith & Fulham, Wandsworth, Lambeth, Southwark, Hackney, Tower Hamlets, Greenwich, Lewisham, Haringey, Barnet, Brent, Ealing, Richmond, Kingston, Croydon, Bromley, Newham and Waltham Forest — plus the remaining boroughs on request.
Structural engineering for London homes and small commercial projects
London’s building stock is incredibly varied: Victorian terraces, period townhouses, post-war estates, converted flats, and contemporary developments. Typical structural “usual suspects” include open-plan alterations in terraced homes, steel beam design and bearings onto masonry, roof/loft strengthening, and careful detailing for party-wall conditions.
We keep deliverables practical: clear assumptions, buildable details, and drawings that builders can follow — while keeping Building Regulations compliance front and centre.
1) Internal alterations (open-plan living)
Creating or widening openings in load-bearing walls, specifying beams/posts/padstones, and checking bearings and stability (with clear notes for builders).
- Beam sizing + connection notes
- Padstone / bearing checks
- High-level temporary works guidance
2) Extensions (rear / side / basement works)
Structural design for extensions and renovations including steelwork, lintels, and tie-ins to existing houses. Where applicable, we coordinate with architect plans and site constraints.
- Load paths + member sizing
- Opening/lintel design
- Coordination with architectural layouts
3) Loft conversions
Dormers, ridge beams, floor upgrades, and trimming around stair openings — keeping headroom and buildability in mind.
- Floor joist / beam design
- Support to existing structure
- Builder notes for sequencing
Typical London “project fit” examples
These are examples of the kind of work we often see across London. If yours is similar, we can usually move quickly.
- Terrace open-plan (SW / SE / N): wall removal with beam + bearings, party-wall considerations.
- Townhouse refurbishment (W / NW / WC): new openings, steelwork, local strengthening details.
- Loft conversion (E / N / SW): new floor structure, trimming to stairwell, dormer framing.
- Chimney breast alteration (various): support strategy and load transfer checks.

Tell us what you’re doing and where (borough + postcode), and we’ll recommend the most efficient route: desktop assessment, measured survey requirements, or a site visit.
Tip: For London refurbishments, include whether the wall is party-wall/near a neighbour, and if the property is a flat or a house.
