House extensions in Cambourne & Cambridge

Cambourne’s first homes are now twenty-odd years old, and plenty of them have run out of room before the family has. An extension is almost always better value than moving. No stamp duty, no estate agents, and you keep the school catchment. We build single and double storey extensions across Cambourne and the surrounding villages, from the footings to the final coat of paint, with the brickwork matched so closely it reads as part of the original house.

Single-storey extensions

The most common job we do: a kitchen-diner across the back, a wider living space, or a utility and boot room off the side. On the estate-built homes around Cambourne, Hardwick and Papworth Everard, a single-storey rear extension typically adds the open-plan family space the original layout never had.

We handle the structural opening into the existing house, the steels, the roof (flat, lantern or pitched to match), and all the brickwork, so you’re dealing with one team rather than co-ordinating a bricklayer, a roofer and a groundworker yourself.

Double-storey extensions

When you need a bedroom and a bathroom as well as ground-floor space, a two-storey extension spreads the cost of the footings and roof across far more square metres, so it’s usually the better value per m² of the two.

Matching a double-storey extension convincingly is where bricklaying skill shows. We source brick to match your existing elevations, match the mortar colour and joint profile, and carry the roofline through so the addition doesn’t look bolted on.

One team, footings to finish

We set out and dig the footings, lay the brick and block, fit the structure, and manage the trades that follow, so the job runs to one programme with one point of contact. You get a fixed written price and a real timeline before we start.

Cost

What does an extension cost in Cambridgeshire?

Every extension is different, so we don’t put a price on this page that we’d then have to caveat. The size, the kitchen and glazing spec, the ground conditions and how much structural work is involved all move the figure.

The only accurate number is a measured one. We visit, measure up, and give you an itemised written quotation for free. The figure we start with is the figure we finish with.

Questions

Common questions

Will I need planning permission for my extension?
Many single-storey extensions on Cambourne’s estate homes fall under permitted development, but the new-town planning conditions and estate covenants mean it’s worth checking early. We’ll tell you at the site visit whether your job is likely to need a full application or just a lawful-development certificate, and we can point you to the South Cambridgeshire process.
How long does an extension take to build?
A single-storey rear extension is typically eight to twelve weeks on site, and a double-storey extension around eleven to sixteen weeks. We give you a week-by-week programme with the quote so you know what’s happening when.
Do you match the existing brick?
Yes. Matching brick, mortar colour and joint profile to your existing elevations is core to what we do as bricklayers. On most 2000s Cambourne homes we can source a very close brick match so the extension reads as original.
Do you do the whole job or just the brickwork?
The whole job. We manage everything from footings to final finishes, including the trades that follow us on site, so you have one team and one price rather than co-ordinating it yourself.
