What makes the hup! building system different

Factory precision, on-site speed

Most of a hup! extension is decided before a single panel reaches site. Walls are manufactured in controlled factory conditions, then assembled rapidly once delivered to a Barnsley property.

The smarter way to build

There are many reasons why hup! is a smarter way to build, removing the common frustrations of traditional construction such as long delays, ongoing disruption and rising costs, so your project remains simple, clean and under control.

Patented Ultrapanel technology

This innovative system brings together the strengths of timber and steel framing, enhanced by outstanding insulation. With U-values between 0.12 W/m2K and 0.17 W/m2K, a hup! extension can be up to five times more energy efficient than the average UK home.

Super-strong i-beam structure

hup! wall panels are engineered to be 68% stronger than a standard brick wall, forming a durable i-beam structure as they connect seamlessly, delivering impressive strength across your entire extension.

Rapid connection details

Precision engineering down to the millimetre, combined with patented wall and roof connections, ensures a flawless finish without cold spots. The fast clip-fit system also allows your hup! extension to be built up to five times quicker than traditional methods.

Built off site, finished on site, fast

Because the patented hup! wall arrives largely complete, assembly on site moves five times faster than traditional brickwork, with most extensions watertight inside a week of starting.

Performance figures that hold up to scrutiny

hup! technology delivers U-values of 0.17 for walls, 0.14 for flat roofs and 0.15 for solid pitched roofs, figures that sit well ahead of what a typical brick extension achieves.

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.
