Timber Frame & SIP Building Systems

For over fifty years, Potton has been at the forefront of the self-building market, and our craft has only improved with time. Now, our reputation precedes us, and we work with some of the leading building system and insulation technologies to offer a premium product with a premium performance to match. Our timber frame and structural insulated panel (SIP) systems are measured to exactly match an individual home’s requirements, then engineered and assembled by our team of expert timber-frame builders and erectors. These systems perform highly in terms of thermal efficiency, meaning our builds are low energy and high quality.

Timber is our specialisation, and because we not diversify to other methods like masonry, we have really honed our craft. Our timber frames are made from European whitewood (spruce), which is sourced from sustainable forests in central Europe. All the wood we use is sustainably sourced and subject to a certified chain of custody. Our timber is then measured and custom built to each and every home we create.
