Build & Transform · Structural Alterations
Remove the wall.Keep the building.
Load-bearing removals, steel beam installations, chimney breast removal and whole-layout reconfiguration — engineered, calculated and signed off. Nationwide across the UK.
Head office: Burnham, Buckinghamshire · Working nationwide
Every wall is doing a job. Before we take one down, we work out exactly where that load goes next — and we prove it.
A structural alteration is not demolition — it is a controlled transfer of weight. It begins as a calculation, becomes a beam specification, passes building control sign-off, and only then does the work start. The load always has somewhere to go; our job is to engineer that path.
"Knocking through" is the headline. The engineering underneath is what keeps your home or building standing — the right beam, the right bearing, the right props at the right time, documented at every stage.
We never cut into structure without a structural engineer's calculations and the relevant approvals in place.
What we alter
Specific structural works, engineered end-to-end
Load-bearing wall removal
The core of open-plan living — but every load-bearing wall carries weight from above. We calculate that load and transfer it into a correctly specified beam before a single brick comes out.
Steel (RSJ) beam design & installation
Sized, specified and installed to engineer's calculations with correct bearings and padstones — the component that holds the opening open.
Chimney breast removal & gallows bracket support
Removing a breast leaves the stack above unsupported. Gallows brackets or beams carry that remaining load safely.
Knock-through / open-plan reconfiguration
Combining rooms means re-routing structure. We plan the full load path before layouts change.
Floor & roof structure alterations
Altering joists, trimmers or trusses changes how loads travel — each needs recalculating, not assuming.
Opening formation for doors, bi-folds & wide spans
Wide external openings demand robust lintels or beams — the wider the span, the more deliberate the support design.
Underpinning & foundation support works
When ground or foundation can't take the load, we strengthen from below — engineered, phased and monitored.
08 · Structural repairs & crack remediation
Cracks are symptoms of movement. We diagnose the cause, restore the load path and make good — not just fill and paint over.
The controlled sequence
The building is supported at every stage — never the other way around
Initial consultation
Site assessment & measured survey
Structural engineer's calculations
Beam & support specification
Building control approval / Party Wall notices
Temporary support (Acrow props, needling)
Alteration & installation
Inspection, sign-off & handover
No step is skipped. The building is supported at every stage.
Capability, not claims
The depth behind every alteration
Structural alterations rarely stand alone. We also handle the waste clearance, after-builders cleaning and making-good — so one partner carries the project from first prop to final finish.
The compliance differentiator
Compliance built into the structure — not bolted on afterwards

One property. One partner.Every possibility.
An alteration never happens in isolation. Opening up a space triggers waste that needs clearing, dust and debris that need cleaning, and new structure that needs maintaining. Because we operate four coordinated divisions across the full property lifecycle, every one of those is already covered.
