What does a structural engineer do in building design?

They calculate and design the structural elements of a building to ensure it’s strong, stable, and compliant with building regulations.

When do I need a structural design?

You’ll need structural calculations for any project that changes load-bearing elements — such as removing walls, adding an extension, converting a loft, or building a new property.

Can an architect do structural design?

Architects design layouts and aesthetics, but structural engineers handle the technical calculations that make those designs safe and compliant.

Do I need structural calculations for Building Control approval?

Yes. Building Control will require signed-off structural calculations for any work that affects a building’s stability or structure.

How long does it take to get structural design drawings?

Simple projects can be completed within a few days. More complex designs, such as multi-storey or bespoke builds, can take one to two weeks.

What qualifications should a structural engineer have?

Look for membership with the Institution of Structural Engineers (IStructE) or Institution of Civil Engineers (ICE) to ensure professional standards and competence.

Structural designers in KT1

Structural design ensures that buildings and structures are safe, stable, and built to withstand everyday use and environmental forces.

From home extensions and loft conversions to large commercial projects, a qualified structural engineer can provide detailed calculations and drawings to make your project safe, compliant, and efficient.

What structural designers do

A structural designer or engineer analyses how loads and forces act on a structure.

They use advanced software and building regulations to design foundations, beams, columns, and other supporting elements that meet safety standards.

Whether you’re planning a new build or altering an existing property, they’ll help ensure your design meets Building Control requirements.

Working with a structural design specialist early in your project can also help reduce material waste and prevent costly construction issues later on.

How much does structural design cost?

The cost of structural design in KT1 depends on the project’s size and complexity.

For straightforward residential work like a beam calculation or load-bearing wall removal, costs are typically in the region of £250–£750. Full structural design for extensions or new builds may range from £800–£2,500+, depending on scope and detail required.

Most engineers provide a fixed quote once they’ve reviewed your drawings or site plans.
