You love where you live, but the house has stopped fitting the way you use it. The kitchen's too tight, there's nowhere to sit together, and moving would mean leaving the street, the schools and the neighbours you actually like. A house extension gives you the space without the move.
C&W General Building has built extensions across St Neots, Eynesbury, Little Paxton and the wider Cambridgeshire area, taking each one from the first design sketch through to building control sign-off, so you have one team accountable for the whole job.
Recent work includes a single storey extension with a veranda roof, a larger en-suite bedroom and a fully landscaped garden.
How much does a single storey extension cost in St Neots?
A single storey extension in the St Neots area typically costs between £30,000 and £70,000, depending on the floor area, the quality of the finish, and whether it includes a new kitchen or bi-fold doors. A straightforward rear extension to enlarge a kitchen-diner sits in the lower-to-middle of that range.
A double storey extension, which adds a room upstairs as well as down, costs more per project but far less per square metre, because you're building one set of foundations and one roof for two rooms. We price every extension in detail and walk you through the quote before you commit, so you can see exactly what you're paying for.

Common questions about house extensions in St Neots
How much does a single storey extension cost in St Neots?
Most single storey extensions in the St Neots and Huntingdon area cost between £30,000 and £70,000, with the final figure driven by size, finish and whether a new kitchen or bi-folds are included. A double storey extension costs more overall but less per square metre. We provide a detailed, itemised quote before any work begins.
Do I need planning permission for an extension?
Many single storey rear extensions fall under permitted development, within set size limits. Larger extensions, double storey projects, properties in conservation areas and listed buildings usually need full planning permission. We check the rules for your specific property and handle the application where one is needed.
Do I need building regulations approval?
Yes, all extensions require building regulations approval regardless of planning. Building regs cover foundations, structure, insulation, drainage, electrics and fire safety. C&W manages the building control application and all inspections, and you receive a completion certificate at the end.
How long does an extension take to build?
A single storey rear extension usually takes around 8 to 12 weeks. A double storey or wrap-around extension typically runs 12 to 16 weeks. Groundworks, weather and the complexity of the design all affect the timeline, which we agree with you before we start.
Can you work with my architect's drawings?
Yes. We regularly build to plans drawn up by architects and structural engineers across Cambridgeshire, and we're happy to liaise with yours throughout. If you don't have drawings yet, we can point you to the right people and manage the process for you.
Will an extension disrupt the rest of my house?
We plan every extension to keep as much of your home usable as possible, and we protect finished areas from dust and traffic. There's no avoiding some disruption with building work, but we keep the site tidy, work to the agreed hours and keep you updated so you always know what's happening next.
