Structural Works

Load-bearing wall removal, structural steel installation and underpinning — engineer-signed, and planned around your property's actual construction, not a generic assumption.

Structural Works by GML Construction in North London

Structural work underpins almost everything else

Open-plan kitchens, loft conversions and extensions all usually depend on structural work happening correctly first — removing a load-bearing wall, installing steel beams, or underpinning foundations. Get this wrong and everything built afterward is compromised.

We work directly with structural engineers on every project involving load-bearing changes, and we don't proceed on any wall removal without proper calculations and building control sign-off.

What's included

  • Load-bearing wall removal with steel beam installation
  • Underpinning for extensions and basement conversions
  • Structural engineer liaison and building control sign-off
  • Foundation assessment on period properties
  • Structural surveys ahead of extension or loft projects

Working with older foundations

Victorian and Edwardian properties were built to different structural standards than modern homes, which matters significantly when extending or underpinning. We factor this into every structural quote rather than pricing as if it were a standard new-build foundation.

Building strength, solid foundations, safe structures

Our team of skilled engineers and construction professionals ensures the foundations of your building are as strong as the designs are stunning.

  • Foundation laying — the starting point of any sturdy construction and essential to stability.
  • Wall construction — creating the core structure that supports the entire building.
  • Roofing systems — protecting from the elements and contributing to overall integrity.
  • Support beams and columns — the pillars of strength supporting large spaces and upper floors.
  • Concrete works — from slabs to structural frames, a solid and enduring framework.

Ensuring safety and compliance

  • Safety-first approach, adhering strictly to building codes and regulations.
  • Quality materials and construction techniques on every project.
  • An expert team of engineers and construction professionals.

Common questions

Do I need a structural engineer for wall removal?

Yes, for any load-bearing wall — we work with structural engineers as standard on this kind of work, and building control sign-off is required regardless of how straightforward the wall looks.

How do I know if a wall is load-bearing?

It's not always obvious from appearance alone — we assess this properly at the site visit rather than guess, since getting it wrong has serious safety and structural implications.

Does structural work disrupt the rest of the house?

Some disruption is unavoidable, but we sequence structural work to minimise it and will walk you through exactly what to expect before work starts.
