Get more living space without having to move

Moving house can be expensive, stressful, and full of compromise. A well-planned extension gives you the extra space you need while letting you stay in the home you already love. We build house extensions that open up kitchens, create better dining areas, add family rooms, and make space for a practical home office. We shape every project around your property, your routine, and your budget, so the new space feels useful from day one. 

 

Gareth Bilkey Building Contractors Ltd handles the full process from early ideas through to completion, keeping the work organised and easy to follow. With strong experience in structural work, brickwork, foundations, and construction, we make sure your extension feels like a natural part of your home rather than an awkward add-on. Based in Newquay, we undertake property extensions across Cornwall.

A build process that keeps things clear

From the first consultation, we take time to understand your need for more space and how you want it to work. Some households need room for a growing family, while others want more natural light or a calmer home working area. 

 

We can guide you through single-storey, double-storey, rear, side-return, wraparound extensions, conservatories, and landscaping options, explaining what most suits your layout. Our team also supports planning permission and building regulations, helping reduce stress later in the process. Gareth Bilkey Building Contractors Ltd manages each stage carefully, using trusted materials and keeping the project on track.
