Extensions

Radburn Building Services

At Radburn Building Services, we design and build high-quality extensions for homeowners throughout Witney and across Oxfordshire. Whether your family is growing, you work from home or you simply need more room to enjoy everyday life, an extension can give you the space you need without having to move.

As a local, family-run builder, we’ll take the time to understand what you want from your home. Together, we can create an extension that feels like a natural part of the property and works perfectly for you.

Different Types of Extensions

Depending on your property and the space available, we can build a range of home extensions across Oxfordshire.

Single-storey extensions: A popular way to enlarge a kitchen, create an open-plan living area or add a useful new room to the ground floor.

Double-storey extensions: Ideal when you need more space on both floors, such as a larger kitchen downstairs with an additional bedroom or bathroom above.

Rear extensions: Make better use of the space behind your property and create a stronger connection between your home and garden.

Side-return extensions: Use the narrow space beside your home to widen a kitchen or improve an existing ground-floor layout.

Wraparound extensions: Combine side and rear extensions to create a generous amount of additional living space with greater freedom over the layout.

A Valuable Addition to Your Home

A well-planned extension can completely change how your home looks, feels and functions. It can give everyone more room, introduce more natural light and make previously cramped or unused areas feel open and practical.

Extensions may also add value to a property, particularly when the new space has been carefully designed and completed to a high standard. Our experience with both extensions and new builds means we understand how to create spaces that are practical, attractive and made to last.

Built with Care from Start to Finish

We know that having building work carried out at home can feel like a big undertaking. That’s why we aim to make the process as straightforward as possible, with clear communication and careful workmanship throughout.

We’ll treat your home with respect, keep you informed as the project progresses and pay close attention to every detail. As a trusted local builder, we take pride in creating extensions that blend beautifully with the original property while giving you the extra space you need.

Testimonial 1

We asked Radburn Builders to provide a quote to build our single storey rear extension, they turned up when arranged and was competitive with their pricing. We opted to use them and we didn’t regret it, they were all very friendly and turned up everyday on time, they worked really hard and overcome unexpected obstacles successfully.  They provide answers for our never ending list of questions and queries and they guided us through it all and reassured us with thier knowledge. We are really happy with the finished product and we would definitely use them again.

Radburn Building Services  constructed a large single storey extension for us which included steel framing to a lantern light. Internally they built a chimney breast with facing brick recess for the log burner. We are delighted with the space and finish.

Radburn Building Services (Tom and his dad, Rad) built a two story extension and made extensive internal alterations to our house in Cumnor from July '24 to Feb '25. They also supervised the other contractors (window fitter, steel erector, joiner, electrician, plumber, plasterer, tiler) for a complete refurbishment of the rest of the property. We dealt directly with the architect and structural engineer. We found Tom friendly, honest and straightforward to deal with. He kept to budget and finished in reasonable time, given the complexity of the project. He flagged up a few variations in price in good time, so we could discuss options and budget accordingly. Tom, Rad and their labourer Nif, did the groundwork, demolition and brickwork. Their groundwork was to building control's satisfaction and their brickwork blended nicely with the original house. They used specialist trades for everything else. This resulted in a very professional approach to all aspects of this build, though it should be noted that availability of follow-on trades can impact your schedules, through no fault of the main contractor. When the building project was complete, we also engaged Radburn to relay the patio and, through another subcontractor, to relay the gravel drive and parking area.
