House Extensions in Oxford

Create More Space Without the Cost and Stress of Moving

Knights Builders Oxford has been delivering high-quality house extensions across Oxford and the surrounding areas for many years, helping homeowners unlock the full potential of their properties. With Oxford being one of the UK’s most desirable and expensive places to buy a home, moving isn’t always the best option. A professionally designed and built extension allows you to gain the extra space your family needs while adding significant value to your property. Whether you’re planning a spacious kitchen extension, a new family room, a home office, or a two-storey extension, our experienced team will guide you through every stage of the project—from the initial idea to the final handover.

Bespoke Extensions Designed Around Your Lifestyle

No two homes are the same, which is why every extension we build is tailored to your property, budget, and lifestyle. We construct:

Single-storey extensions
Double-storey extensions
Rear and side extensions
Kitchen and dining extensions
Open-plan living spaces
Utility rooms and home offices

If extending isn’t the right solution, we also specialise in loft conversions and garage conversions, transforming underused space into practical, comfortable living areas.

A Stress-Free Building Experience

Building an extension involves much more than construction. Planning permission, architectural drawings, Building Regulations, inspections, and final certification can all seem overwhelming.

At Knights Builders Oxford, we make the entire process straightforward. We work alongside trusted architects, structural engineers, and local building control officers to ensure your project is completed safely, efficiently, and to the highest standards.

Our experienced team keeps you informed throughout the build, delivering exceptional workmanship with minimal disruption to your home.
