Structural Alterations Specialists London
Executing structural alterations is a fundamental step in converting traditional, compartmentalized houses into expansive, modern living environments. Whether you plan to create a vast open-plan kitchen, merge two rooms, or install large bifold doors, modifying load-bearing elements requires absolute precision. Our team of certified structural specialists coordinates layout design, temporary support planning, and heavy-duty steel installation to ensure your property remains perfectly stable throughout the modification process.
Safety and structural integrity are our top priorities during every load-bearing wall removal project we undertake in London. We work closely with leading structural engineers to execute load calculations, select correct RSJ beams, and set up secure padstones. By managing building control inspections and structural certification, we provide homeowners with total peace of mind that their home's core framework is built to last.

The physical work of structural alterations typically begins with the installation of temporary support systems. Before any load-bearing brickwork or partition is removed, our teams often position heavy-duty Acrow props and Strongboy needles to carry the weight of upper floor joists and roof structures. This shoring process is critical to prevent masonry movement and ensure a safe working environment.
Once the temporary props are securely in place, the masonry removal is typically executed. Our bricklayers then cast reinforced concrete padstones on either side of the opening to prepare for the steelwork. The new RSJ steel beams are often hoisted into place using specialized lifting equipment, bolted together, and dry-packed with non-shrink slate. After building control inspects the steel, we typically apply fire-resistant plasterboard or intumescent coatings before removing the props.
Our Structural Alteration Process
Design & Calculations
We review architectural drawings and obtain structural engineering calculations to determine steel sizes, loading specifications, and padstone sizes.
Temporary Shoring & Demolition
We install heavy-duty steel Acrow props to secure the load before carefully knocking through the masonry wall.
Steel Installation & Sign-Off
We lift and secure the RSJ beams, dry-pack the connections, apply fireproofing, and coordinate the final building control inspection.
Frequently asked questions
Determining whether a wall is load-bearing requires assessing its thickness, composition, and direction of floor joists above. Solid brick walls, walls supporting joists, or walls located directly above other walls are typically load-bearing. We always recommend a structural engineer's site inspection to confirm load distribution.
An RSJ (Rolled Steel Joist) is a heavy-duty steel beam designed to carry structural loads across a span. When a load-bearing wall is removed, the RSJ acts as a header beam, transferring the weight of the upper floors and roof to concrete padstones at either end, maintaining the building's stability.
Internal structural alterations do not typically require planning permission unless the building is listed or situated in a conservation area with specific local directives. However, all structural modifications must comply with Building Regulations and require a building control notice and sign-off.
If your structural work involves cutting into or placing steel beams onto a shared boundary wall with a neighbor (a party wall), you must serve a Party Wall Notice under the Party Wall etc. Act 1996. This must be agreed upon before physical works begin on site.
