Extensions, Alterations & Loft Conversions

Structural Engineering for Alterations, Extensions & Loft Conversions

Altering or extending an existing building requires a smart structural strategy to unlock space, ensure constructability, and protect the building’s integrity. We provide practical, buildable engineering solutions across London and the home counties for residential and commercial properties of all sizes.

End-to-End Engineering Support

  • Concept & Early Design: For complex reconfigurations or spatial challenges, we produce clear initial sketch details to explore structural options alongside the architect and client before final details are locked in.
  • Design & Approvals: We deliver comprehensive calculation packages, structural drawings, and connection details fully tailored for Building Control approval and accurate site construction.
  • Ongoing Site Support: Our involvement doesn’t stop at the drawing board. We remain accessible throughout the build to answer contractor queries and keep your project moving smoothly.

Maximizing Space: Specialist Loft Conversions A seamless loft conversion requires careful structural planning to maximize usable floor area and headroom without over-complicating the steelwork. By analyzing load paths and floor depths thoughtfully, we help architects and homeowners achieve spatial efficiency and clean architectural design.
