House Extensions 
In Cornwall 

Single & Two Storey Extensions.
Designed and Built by One Team.

Oliver Group Construction Ltd build house extensions throughout Cornwall, helping homeowners create more space without the cost of moving.

From single storey and two storey extensions to kitchen extensions and open plan living spaces, we handle every part of the job with a professional and personal approach.

We work with a structural engineer and architect, so the calculations, design and build are all handled by one team, with one point of contact from groundworks to final sign-off.

Whether you need a bigger kitchen, an extra bedroom or more room for the family, we're here to discuss your plans and help you take the next step.
