House Extensions, Garage Conversions & Renovations

House Extensions

At 1st Builders Cambridge, we are extremely adept in all aspects of professional building work, specializing in house extensions. While hugely increasing the value of your home, a house extension can provide you with a large, open-plan contemporary kitchen, a new ground floor bathroom, or simply just an expanded living space.

Garage Conversions

Our team at 1st Builders Cambridge are experts at turning garages – cold, damp, under-utilised spaces – into warm, habitable parts of the house. Whether you want to extend your living room, create a new, larger contemporary kitchen, a home cinema, a playroom for the kids or a new home office, we can oversee the entire project from start to finish, while creating minimal disruption to the rest of your home.


1st Builders Cambridge’s expert teams of Contracts Managers, kitchen and bathroom designers, and carpenters are on-hand to help you plan your renovation. Whether you want a beautiful new kitchen or tranquil bathroom to replenish and relax, 1st Builders Cambridge can offer the ideal solutions. We provide a huge range of cupboards, appliances, plumbing, taps, basins, baths, and toilets to create a highly bespoke look for every budget and style.


At 1st Builders Cambridge, our expert teams of contracts managers, kitchen designers and skilled carpenters are always on hand to help you plan your kitchen and are available to give you as much or as little help as you may need. As well as fitting and plumbing-in kitchens, we can create extra storage under the stairs or simply install cupboards for you.


1st Builders Cambridge are the local leading experts in bathroom installs and renovations. We offer a huge selection of materials and units from a wide range of quality suppliers to create a highly bespoke look for every bathroom. We can provide anything from small cloakroom toilets, large Jacuzzi, corner baths, efficient ventilation units and entirely refitted bathrooms for elderly people or those with disabilities.


1st Builders Cambridge offer the entire range of groundwork services to both domestic and commercial clients and regularly complete groundworks contracts for homeowners, commercial buildings, builders, local authorities and schools. Our expert team of excavators can provide the relevant groundworks service for whatever job needs doing; whether that is laying foundations, working on excavations, drainage and sewage or repairing driveways and fencing.

Great job! 1st Builders Cambridge were on time and on budget – extremely friendly and professional. I am very happy with my extension!

House extension in Sawston, Cambridge

The experience we had was truly amazing. We were worried because we had heard horror stories of home renovations; however, the standard of 1st Builders Cambridge’s work was beyond our expectation and the service was incredible.

Throughout the project, Mark the surveyor was there for all our requests and we now have a beautiful home extension!

We are both delighted with the new extension to our home. 1st Builders Cambridge were recommended to us by some friends who had used them last year. We would happily recommend them to anyone.
