Overview
Our structural engineers in London prepare calculations, beam and foundation designs and full structural packages for extensions, conversions and new builds. Because the same company builds the work, our designs are practical to build.
We cover 9 councils across South West London and Surrey, and every project is run by one team from survey to sign-off. It is often combined with architectural drawings and house extensions.

Costs and timescales
