Explaining hup!

A Faster, Smarter Build for Hampshire Homes

The hup! system is an innovative building method that cuts weeks, or even months, off standard construction timelines. By swapping out slow, traditional brickwork and timber roofs for state-of-the-art Ultrapanels, our local installation teams can deliver a fully finished extension up to five times faster than conventional builds.

For you, this means a remarkably hassle-free home improvement project. Work that might typically cause months of disruption is condensed into a matter of days. Furthermore, the hup! process is entirely streamlined: you won’t need to hire an external architect. Your dedicated project designer will manage everything from start to finish, handling all local building regulations and providing a single, reliable point of contact for a perfectly smooth, stress-free build.

hup! Technology

Advanced Ultrapanel Technology

At the core of every hup! build is Ultraframe’s patented Ultrapanel technology, providing unmatched thermal insulation for your property. By fusing the best of steel and timber framing, hup! walls achieve incredible U-values of between 0.12 and 0.17 W/m²K. This easily surpasses current Building Regulations, making a hup! extension up to five times more energy-efficient than the average UK home—which is ideal for keeping your heating bills down during those chilly winter months.

Precision engineering ensures your build is structurally flawless. Every component is manufactured down to the exact millimetre, featuring seamless clip-fit connections that guarantee a weatherproof finish with zero cold spots or draughts. Despite its rapid assembly, the interconnected wall panels create a highly rigid i-beam structure. You can rest assured knowing your new hup! extension is just as robust and long-lasting as a traditional brick build, offering decades of reliable performance.
