Loft Conversions in Cambridge
Camacre designs and builds loft conversions across Cambridge and Cambridgeshire, turning unused roof space into bright, usable rooms, all managed by one accountable team.
Our loft conversion service
As a loft conversion Cambridge specialist, Camacre designs and builds bright, usable rooms in the roof and manages the whole job in one place: design, structural work, planning, building regulations and interior finishing. That means you deal with a single team from the first survey to the finished room, with no need to coordinate separate architects, builders and trades.
Because we also build extensions and conversions, fit kitchens and bathrooms and offer interior design, your loft can be delivered on its own or as part of a wider project on your home. Our in-house architects are involved from the start, so the design is practical to build and right for your property.
Loft conversion Cambridge, managed by one team
Camacre is a Cambridge design-and-build company, not a broker, so the team that designs your loft conversion also builds it. You get one point of contact, in-house architects and a focus on high-quality, lasting finishes.
With offices in Cambridge and Mayfair and a portfolio of residential work across Cambridgeshire, we are a trusted loft conversion company for homeowners who want the job managed properly from start to finish.
Types of loft conversion
There are four main types of loft conversion, and Camacre builds all of them in Cambridge. At your consultation we advise which suits your roof, budget and how you want to use the space. For a full comparison, read our guide on the types of loft conversion.
Dormer
A box-shaped structure that projects from the roof slope, adding head height and floor space. The most common choice for Cambridge semis and terraces.
Hip-to-gable
Extends a sloping hip end out to a vertical gable wall for significant extra volume. Ideal for detached and end-of-terrace hipped roofs.
Mansard
Rebuilds the roof with a near-vertical rear wall and flat top for the most space of any loft type. Best for period and city-centre homes, usually needs planning.
Velux (rooflight)
Keeps the existing roof shape and adds windows into the slope. The most cost-effective option where the roof already has enough head height.
How much does a loft conversion cost?
The cost of a loft conversion in Cambridge depends on the type, size and finish. A rooflight conversion is the most affordable, while dormer and mansard conversions cost more because of the additional structural work. As a guide, most loft conversions in Cambridge fall between £45,000 and £70,000.
| Type | Guide price | Best for |
|---|---|---|
| Velux (rooflight) | from £45,000 | Roofs that already have head height |
| Dormer | £50,000 to £65,000 | Semis and terraces needing head height |
| Hip-to-gable | £55,000 to £68,000 | Detached and end-of-terrace hipped roofs |
| Mansard | up to £70,000+ | Period and city-centre homes wanting maximum space |

How long does a loft conversion take?
Most loft conversions in Cambridge take between 8 and 10 weeks on site, plus a few weeks beforehand for design, drawings and approvals. A rooflight conversion is at the quicker end, while a dormer or mansard sits at the longer end because of the extra structural work.
Before we start, we give you a written programme with the key stages and dates, and we keep you updated throughout the build. See our full loft conversion timeline for a week-by-week breakdown.
Do you need planning permission?
Many loft conversions in Cambridge can be carried out under permitted development, which means they do not need full planning permission. Rooflight and modest dormer conversions often fall within these rights. Mansard conversions, larger dormers, and homes in conservation areas or listed buildings usually do need permission.
Our in-house team checks your property, advises you early, and manages any planning application and building-regulation approvals on your behalf. Read more in our guide to loft conversion planning permission.
