Create the extra space your home has been missing 

Home improvements offer a practical way to gain more space without the disruption of moving. We deliver a full range of solutions, including new builds, single/double-storey builds, rear and side additions, kitchen projects, garage conversions, home extensions, open-plan living conversions, structural alterations, property renovations, and all groundwork and foundation work. With hands-on experience, Gareth Bilkey Building Contractors Ltd transform inefficient layouts into functional, well-balanced spaces for properties across St Austell that improve everyday living. 

 

If your home feels overcrowded, you have limited storage, or need an additional space to improve day-to-day comfort, a home extension is the perfect solution. We manage every stage of the build, ensuring clear communication and consistent progress throughout. Gareth Bilkey Building Contractors Ltd provides a structured approach for homeowners looking for long-term value and practical improvements.

Experiences that speak for themselves

Garath did a great job with laying stepping stones and brick edging around the front garden. I found him to be hard-working, respectful and honest. I wouldn't hesitate to recommend him to anyone and hope to use him again in the future.

A build that works for your property

Every home requires a tailored approach, so we design each extension around the existing structure and the intended use of the space. Whether it is a rear extension for family living, a side extension to maximise unused space, or an open-plan conversion to create a brighter layout, we ensure that the new addition integrates properly with the original building. 

 

Our experience in structural alterations, renovations, and complex construction work helps achieve a seamless finish that feels natural rather than added on. We also coordinate all key stages of the project to maintain steady progress and clarity throughout. This straightforward approach helps homeowners stay confident and informed at every stage.

Why extending often makes more sense than moving 

A well-planned extension can significantly improve how a home functions by creating better flow, increasing storage, and defining clearer living zones. It allows homeowners to make better use of their existing property while avoiding the cost, stress, and disruption associated with moving.
