When work affects a wall or foundation shared with a neighbour, the Party Wall etc. Act 1996 usually applies, and party wall surveyors agree how the work will be carried out. Often they need a structural engineer to confirm the design is sound and that the neighbouring property will be protected.
How we help
For the building owner: we design beams, connections and foundations that bear on or near the party wall, and set out the temporary support and sequence of work so the neighbour’s side stays stable.
For surveyors acting for either side: we review the structural calculations and drawings submitted with a party wall notice, and comment on anything that needs clarifying before an Award is agreed.
During the works: we can advise on temporary propping, check what is found on opening up, and respond quickly if conditions differ from what was expected.
Typical situations
- Steel beams bearing into a party wall in a terraced or semi-detached house
- Basement or lower-ground extensions close to a neighbour’s foundations
- Chimney breast removal on a shared wall (see someone already removed the chimney breast)
- Loft conversions that raise or cut into a party wall
Working with the wider team
We work alongside party wall surveyors, architects and contractors rather than replacing any of them. Our role is to give the structural answer clearly enough that everyone can agree and get on with the job.
Structural engineering support is available from our Peterborough and London offices. Send us the notice or drawings.
