Energy efficient hup! building system

At the core of every hup! extension we build is advanced Ultrapanel technology, designed to deliver exceptional accuracy, strength, and thermal performance. Manufactured with precision, the system ensures consistent build quality while achieving energy efficiency levels that outperform many traditional construction methods.

As hup! can be assembled in virtually all weather conditions without the need for on-site cement, projects stay cleaner, more efficient, and far less vulnerable to delays. It's an innovative extension solution that's transforming how homeowners across Norwich expand their living space.

Super-strong i-beam structure

hup! wall panels are 68% stronger than a brick wall thanks to the collective force of the panels, which rapidly clip together to form a super-strong i-beam structure throughout your hup! extension.

Tried and tested by UK Housebuilders

The Ultrapanel technology used in hup! has been adopted by leading UK housebuilders to construct new houses. Every building material used on a new house needs approval from the NHBC who insure all new homes and the hup! technology has therefore been thoroughly assessed and accredited by both the BBA and the NHBC.
