How we help across Cambridge & Ely
A closer look at what each service involves and where we work across Cambridgeshire.
Home Extensions
Add space, light and value with a single or double-storey extension, wrap-around or kitchen-diner. We handle everything from design and planning to the final finish, working on period and modern homes across Cambridge, Ely and villages such as Trumpington, Cherry Hinton and Histon. Whether you are opening up the back of a Victorian terrace or extending a growing family home, we build to last — on time and on budget.
Full Renovations
Complete property transformations, from tired interiors to full refurbishments and period restorations. We sensitively renovate older Cambridgeshire homes in areas like Newnham, Grantchester and Ely while upgrading them for modern living — rewiring, replastering, new kitchens and bathrooms, and energy-efficient improvements — all coordinated under one trusted team.
Groundworks & Foundations
The solid base every project needs. We carry out excavation, drainage, footings and foundations engineered to suit your site and soil conditions across Cambridge, Ely, Waterbeach and Milton. Get this stage right and everything above runs smoothly — which is why we never cut corners on the groundwork.
Structural Alterations
Open up your home with confidence. We install steel beams (RSJs), remove load-bearing walls and reconfigure layouts for open-plan living in homes around Cambridge, Sawston and Great Shelford — all carried out safely, with structural-engineer calculations and full building-regulations sign-off.
Landscaping & External Works
Finish your project inside and out. We build patios, driveways, garden walls, paths and outdoor living spaces that complement the property and make the most of your garden, for homes across Cambridge, Ely and Cottenham — practical, hard-wearing, and built to the same standard as our interior work.
New Builds
Bespoke new homes built from the ground up. We manage the entire process — groundworks, structure, services and finishes — delivering individually designed properties across Cambridgeshire, from Soham to Girton, with meticulous attention to detail and clear communication throughout.
Project Management
One point of contact for your whole project. We coordinate trades, schedules, materials and budgets so your build runs smoothly from first consultation to final handover, anywhere across Cambridge, Ely and the surrounding Cambridgeshire villages — keeping you informed at every stage and removing the stress of managing it yourself.

Questions, answered
Common questions from homeowners across Cambridge, Ely and Cambridgeshire.
Which areas do you cover?
We are builders based in Cambridge and work throughout Cambridge, Ely and the surrounding Cambridgeshire villages, including Histon, Milton, Waterbeach, Sawston, Soham and Cottenham. If you are unsure whether we cover your area, just ask.
Do you offer free quotes?
Yes. We provide a free, no-obligation consultation and a clear, itemised quotation with no hidden costs, so you know exactly what your project will cost before any work begins.
Are you fully insured and do you work to building regulations?
Yes. We are fully insured and all of our work is carried out in compliance with current UK building regulations. We can also help arrange the necessary approvals and inspections.
Can you help with planning permission and drawings?
Absolutely. As part of the design and quote stage we can help with architectural drawings, planning applications and building-regulations approval, coordinating with architects and the local authority on your behalf.
How long does a typical home extension take?
It depends on size and complexity, but a single-storey rear extension in the Cambridge area typically takes around 10–14 weeks from breaking ground to completion. We give you a realistic schedule in your quote and keep you updated throughout.
Do you provide a guarantee on your work?
Yes. We stand behind the quality of our workmanship and provide aftercare you can rely on. Full details are confirmed in writing as part of your project.
