Working with us

For homeowners

We work with homeowners on extensions, alterations and structural works, managing projects from first discussion through to completion. Expect straightforward advice, clear communication, and a considered approach throughout the build.

For architects

We regularly work alongside architects and consultants on residential projects involving structural alterations and extensions. We understand the importance of detail, coordination and buildability, and value long-term working relationships built on reliability and trust.

“George helped me when I needed it most. He was called to repair my property after a cowboy builder did dodgy work to my foundations, leaving me £25k out of pocket — and he fixed it despite the structural engineer’s ever-changing requirements. A caring, professional builder. I’d give him ten stars if I could.”

Common questions

What type of work do you specialise in?+

Structural alterations, extensions and associated building works for domestic and commercial properties — load-bearing wall removals, steel beam installations, foundations, structural repairs, knock-throughs and wider extension projects. Our work is particularly suited to projects where the structural element needs to be properly planned, coordinated and built in line with drawings, calculations and Building Control requirements.

Do you manage the project from design through to completion?+

Yes. We can manage the full process from early planning through to the completed build. Where required, we work alongside architects, structural engineers and Building Control. If you already have drawings and calculations we can quote on the agreed scope; if not, we can recommend trusted professionals before the build begins.

How do you approach pricing and quotations?+

We price on the confirmed scope, site conditions, drawings, structural information and level of finish required. We aim for a clear, realistic quotation rather than a low estimate that later changes. For fixed-price quotations we provide a clear scope of works, assumptions, exclusions and payment stages so the quotation is transparent.

Are you insured, accredited and Building Control compliant?+

Yes. We are fully insured and hold recognised accreditations including TrustMark and Checkatrade. Where Building Control approval, structural calculations or inspections are required, we make this clear at quotation stage and work with the relevant professionals to ensure the work is carried out correctly.
