The Home of Steel Beam Calculations & Structural Calculation Packages for Building Control Approval in England and Wales

We can assist you with everything you require to enable Building Control approval from a one-off single steel beam calculation for an internal alteration, removal of a load-bearing wall, structural ridge beam or insertion of bi-folding doors in an external wall, through to full structural calculation packages for loft conversions, home extensions, new build dwellings, and renovation schemes. Simply email us your plans or measured survey sketches to benefit from our bespoke fast and affordable nationwide steel beam design service.

We understand the importance of getting accurate and reliable structural calculations when working on a domestic building project.


We have been using this helpful small company for years for domestic extension structural packages and structural calculations for loft conversions. They always find a practical solution and are willing to chat through my ideas, to help save the client money.
