Yes, a structural engineer is required for most house extensions to calculate the load-bearing requirements of new walls, roofs, beams, and foundations. These structural calculations are essential for Building Control approval and to ensure your extension is safe and compliant.

Absolutely. If you're removing a load-bearing wall, a structural engineer will assess the structure and specify the correct size and type of RSJ (Rolled Steel Joist) needed to support the load above. These calculations are submitted to Building Control for sign-off.

Structural engineer costs in London typically range from £250+, depending on the complexity of the project. At Shorplans, we offer transparent, fixed-fee quotes for all structural work, including calculations, drawings, and Building Control support.

An architect focuses on the design, layout, and aesthetics of a building, while a structural engineer ensures the building is structurally sound and meets safety standards. Most projects benefit from both working together — which is why Shorplans coordinates both services in-house.

Yes, Building Control often requires structural calculations for any work involving changes to load-bearing walls, foundations, beams, or roof structures. These calculations must be provided by a qualified structural engineer to demonstrate the work complies with UK building regulations.

Yes, we provide detailed structural drawings alongside your calculations. These drawings show how beams, columns, and supports should be installed — helping builders work accurately and speeding up Building Control approval.

It’s best to engage a structural engineer once you have a rough layout or architectural plan. Early involvement helps avoid delays, ensures your design is structurally feasible, and allows for accurate budgeting before you start construction.

Yes. If you're concerned about cracks, movement, or possible subsidence, a structural engineer can inspect the property and provide a professional report outlining the cause and necessary remedial work. These reports are often used for insurance or mortgage purposes.

Yes, loft conversions typically require structural input to calculate beam sizes, floor loading, and support for dormers or roof alterations. Our engineers provide all required calculations and drawings to get Building Control approval.

Yes — if you're only making structural changes like removing a wall or installing a beam, we can often work from basic measurements or arrange a site visit. For more complex projects, architectural drawings will help us provide a more accurate assessment.
