About this service
About structural alterations
Structural alterations involve changing the load-bearing elements of a property to create a new layout or support further building works. This can include removing internal walls, forming larger openings, installing steel beams, modifying floor structures, strengthening existing walls, or reconfiguring multiple rooms. These projects typically start from £15,000 and require structural calculations, careful sequencing, and Building Regulations compliance.
Who it's for
Homeowners and developers who want to create open-plan spaces, improve circulation, combine rooms, prepare for extensions, or upgrade a property with a tired and restrictive layout. Structural alterations are often the key stage in full renovations and high-value remodelling projects.

Process
How it Works
Engineering Review
We review the drawings, calculations, and site conditions so the method of work, sequencing, and temporary support are all planned properly.
Propping & Structural Work
Areas are prepared, temporary supports are installed, walls or sections are removed, and the new structural members are fitted safely.
Making Good & Sign Off
We complete fire protection, close up the structure, make good the affected finishes, and coordinate Building Control sign off.

What homeowners say
What homeowners say about working with us on structural work.
“We hired Brits Construction for a large, double storey, wrap-around extension with piling, extensive structural work in the existing part of the property, a 70m2 patio and 50m2 driveway. We requested all-inclusive pricing to minimise the number of contractors. Brits Construction provided an exhaustive, detailed contract with a breakdown of costs under each section. Payment was due once each section was completed. Costs within the contract was adhered to and did not inflate during the project. The extension is solidly built, with a high level of craftsmanship and I am happy with the work done.”

Review on MyBuilder
“I have just had a garage conversion and rear extension to garden via a bifold door, with a steel framework completed by Brits. As part of the work they also had to extend the central heating system and fully wire the area. The quality of work has been very good, the tiling work is excellent and the general finish is great. The workers have been reliable, clean and efficient and the project has been completed to the price agreed. Overall an excellent service and I will use them again in the future.”
