About SBS Structural Engineers.
We're a small, focused team of structural engineers based in Ilford. Every project we take on is residential — loft conversions, extensions, chimney breast removals, steel beam designs, and structural surveys. That's all we do, and we've gotten very good at it.
We work directly with homeowners, as well as architects and builders who need reliable structural calculations and drawings. Our designs are prepared for Building Control approval, and we typically turn things around in about one week.
If you're planning a home project and need a structural engineer, we'd be happy to have a chat — no obligation, no jargon.
