Structural loft work
The structure beneath every loft
Every loft conversion rests on structural work that is invisible when finished but essential to safety and compliance.
We assess your existing floor joists, roof structure, and load-bearing walls to determine what structural alterations are required. Steel beams replace or support existing timbers, floor joists are strengthened or replaced, and chimneys are removed or partially taken down where they restrict usable space.
Our structural work is backed by engineering calculations and submitted to building control for approval. We coordinate inspections at key stages — when steel is in place, when floors are strengthened, and when the roof is altered — so your loft conversion meets all regulatory requirements and performs safely for decades.
What we deliver
Every detail engineered
Steel beam installation
Universal beams and columns specified by structural engineers — craned in and installed with fire protection and padstones.
Floor strengthening
Existing joists reinforced or replaced with engineered timber or steel — creating a floor capable of domestic loading.
Chimney removal
Redundant chimney stacks and breasts removed or partially taken down — freeing space and reducing load on the structure.
Roof alterations
Rafter modifications, dormer framing, and hip-to-gable construction — roof work engineered for the altered geometry.
Building control liaison
Structural calculations submitted, inspections booked, and approvals obtained — compliance managed throughout.
