Structural engineers for London and Hertfordshire
Our London office is at the Kinetic Business Centre on Theobald Street. From here we work with homeowners, architects, builders and developers across North London and Hertfordshire, including Barnet and Elstree, on everything from a single beam to a full new build.
London homes come with their own puzzles: Victorian terraces with chimney breasts removed decades ago, shared party walls, basements and rear extensions squeezed onto tight plots. We’ll look at what’s there, explain what it means, and design what your builder needs to get on with the job.
What London clients ask us to help with
- Knock-throughs and open-plan kitchens. Beam calculations and details for Building Control. How load-bearing wall removal works
- Chimney breast removals. Including the ones a previous owner took out without support. Is a removed chimney breast safe?
- Rear and side extensions, lofts and dormers. Structural design and calculations from planning drawings onwards. Can your roof take a loft conversion?
- Party wall work. Structural input where your project meets a neighbour’s wall or foundations.
- Cracks, movement and subsidence. Surveys that explain what the cracks mean and what to do next. Trees and subsidence
- Conservatories and glazed extensions. When a conservatory needs a structural engineer
- Temporary works. Propping, needling and excavation support while part of the building is missing. Temporary works explained

How it works
- Tell us about the job. Send a short description, any drawings and a few photos through the contact form or by email.
- We take a look. Some jobs can be priced from drawings; others need a site visit so we can see the structure for ourselves.
- Calculations and drawings. You get clear calculations and details your builder can work from and Building Control can approve.
- Support on site. If something unexpected turns up once the walls are open, we’re a phone call away.
