Our single storey extension service in Cambridge
A single storey extension in Cambridge is one of the most effective ways to gain a larger kitchen, a bright family room or a home office without the cost and upheaval of moving. Camacre designs and builds the whole project in one place: design, structural work, planning, building regulations and interior finishing, so you deal with a single team from the first survey to the finished room.
As an established name for house extensions in Cambridge, we work on terraces, semis and detached homes across the city and surrounding villages. Our in-house architects are involved from the start, so the design is practical to build, sympathetic to your home and right for how you want to use the space.
Types of single storey extension we build
From a simple rear extension to a full wraparound, Camacre builds every type of single storey extension in Cambridge. At your free consultation we advise which layout suits your home, your budget and your planning situation.
Rear extension
The most popular option in Cambridge. A rear extension opens up the back of the house for a larger kitchen or family room, often with bifold or sliding doors to the garden.
Side extension
A side extension in Cambridge uses a side return or side plot to widen the ground floor, ideal for narrow Victorian terraces and semis that feel cramped.
Wraparound
A wraparound extension combines a rear and side extension in an L shape, creating a large open plan living and dining space that opens up the ground floor.
Kitchen extension
A kitchen extension in Cambridge adds room for a kitchen diner and island, bringing in natural light with rooflights and glazed doors for a light-filled, sociable space.
How much does a single storey extension cost in Cambridge?
The single storey extension cost in Cambridge depends on the size, the ground conditions and the level of finish. As a rough guide, expect around £2,200 to £3,200 per square metre for the building work, with kitchens, glazing and landscaping added on top. The figures below are guide prices for a complete, finished extension.

Do you need planning permission?
Many single storey extensions in Cambridge fall under permitted development and do not need a full planning application, particularly modest rear extensions within the allowed depth and height. Larger extensions, homes on corner plots and properties in conservation areas or listed buildings usually do need permission.
Our in-house team checks your property, advises you early and manages the planning application and building-regulation approvals on your behalf, so you are never left to deal with the council alone. We also recommend a Lawful Development Certificate where it applies, as proof for the future.
How long does a single storey extension take?
Most single storey extensions in Cambridge take between 10 and 16 weeks on site, plus a few weeks beforehand for design, drawings and approvals. A straightforward rear extension is at the quicker end, while a larger wraparound or one with extensive glazing and a fitted kitchen takes longer.
Before we start we give you a written programme with the key stages and dates, and we keep you updated throughout the build so you always know what is happening next.
