Start a free quote →Our fixed fees for structural calculations in Southwark start at £350 for a single beam (wall removal) and £550–£1,050 for a full structural package (loft or extension). Complex basements and multi-storey interventions are quoted individually. All prices include chartered engineer sign-off.
Yes — removing or altering any load-bearing wall in your Southwark property requires structural calculations proving the replacement beam and supports can carry the loads. Building Control will not approve the work without chartered engineer-signed calculations. Even partition walls should be checked before removal.
We deliver structural calculations within 1–2 weeks of receiving the architectural drawings and site measurements. For urgent projects in Southwark, we offer a fast-track service (3–5 working days) at a small premium.
A structural survey is a condition assessment of the existing building — identifying defects, movement, subsidence. Structural calculations are engineering designs for new work — beams, foundations, loft steelwork. For most Southwark extension and loft projects, you need calculations (not a survey). We provide calculations; we can recommend surveyors if a condition survey is needed.
Yes — we offer standalone structural calculations for Southwark projects where you already have architectural drawings from another practice. Just send us the drawings and we quote a fixed fee for the engineering package. If you need both drawings and structural, our Complete package bundles them at a lower combined price.
