Structural Calculations

We provide professional structural engineering calculations for residential projects, supporting everything from simple knock-throughs to full extensions and new builds.

Our in-house structural engineer ensures all designs are safe, compliant, and ready for Building Control approval.


What we do

We produce clear, buildable structural designs and calculations for:

  • Steel beams (RSJs) and lintels
  • Load-bearing wall removals
  • Extensions and loft conversions
  • Foundation design (including raft and traditional foundations)
  • Floor and roof structures
  • Open-plan alterations
  • Outbuildings and garden rooms

All calculations are provided in a format suitable for Building Control submission and contractor use.


Designed to work on site

Our focus isn’t just theory — we design with construction in mind.

That means:

  • Practical solutions builders can actually build
  • Efficient steel sizing to avoid over-specification
  • Clear drawings and notes to reduce site queries
  • Coordination with your architectural plans

Fast and reliable

We understand that structural calculations are often the critical path in getting your project moving.

  • Quick turnaround times
  • Responsive to Building Control comments
