Steel Beam Calculations
Essential for safely supporting load-bearing walls, floors, and roofs when removing internal walls, creating open-plan layouts, or creating larger new opening like for bi-folding doors. These calculations ensure compliance with building regulations and structural safety.

Foundation Design
Accurate calculations are crucial to ensure your extension’s foundation can support the structure. We consider factors like soil type, nearby trees, and any additional loads to provide a stable base.

Roof Structure Calculations
Extending or modifying your roof requires careful design for joists, rafters, and purlins. Our calculations ensure your roof is properly supported, compliant, and blends seamlessly with the existing structure.

Lateral Stability Support
Large masonry removals may need additional supports to maintain the stability of the building. We also assess existing walls, piers, and foundations to ensure they can handle the added load.

Case Study
11 Westminster Road
11 Westminster Road
A new extension to the rear of a property. Initially we were contracted do design the structural steels required for the opening between the new extension and existing house structure, and to support the opening for the new bi-folding doors. While on site the contractor discovered that the existing property had been constructed upon a raft foundation due to historic landfill use of the site, in addition to being congested with a number of publicly owned services. We produced a design for a raft foundation slab to support the new extension that also needed to navigate around the services. Throughout the project we worked closely with the client, contractor and building inspector to ensure compliance with regulations while minimising project disruption.
