Structural Calculations in Swansea & South Wales

Professional Structural Engineering Calculations for Extensions, Loft Conversions, RSJs & Load-Bearing Wall Removals

If you’re planning an extension, loft conversion, removing a load-bearing wall or carrying out any structural alterations to your home, you will need accurate structural calculations to ensure the work is safe, compliant and approved by Building Control.

At CCS SOLUTIONS we provide fully compliant structural calculations for residential and commercial projects across Swansea, Neath, Port Talbot, Llanelli, Bridgend, Cardiff and throughout South Wales.

Our calculations are accepted by all Building Control bodies and follow Part A of the Building Regulations.

Why Structural Calculations Are Essential

Structural calculations ensure your project is:

  • Safe
  • Technically sound
  • Fully compliant
  • Approved by Building Control
  • Ready for construction
  • Cost-effective (no over-engineering)

Every beam, opening and alteration must be properly designed to support existing and new loads. Poor calculations can lead to:

  • Sagging floors
  • Cracking walls
  • Structural instability
  • Collapsed beams
  • Failed inspections

We make sure none of that ever happens.
