Why Choose a hup! Extension for Your Newbury Home?

Engineered by the experts at Ultraframe, the hup! building system is revolutionising the way homeowners in Newbury add space to their properties. If you are dealing with a cold, outdated conservatory that you want to bring into the 21st century, or you simply need to drastically improve your home’s energy efficiency and aesthetic appeal, hup! offers a high-performance solution. The best part? It achieves all this with a build speed that leaves traditional masonry in the dust, keeping site mess and daily disruption to an absolute minimum.

But the hup! system isn’t just for replacement projects; it is a highly versatile option for constructing completely new rear extensions and modern conservatories right across West Berkshire. Furthermore, the KJM team can use this exact technology to build standalone, bespoke garden rooms. Whether you need a peaceful year-round home office, a home gym, or a cozy garden studio, these free-standing structures stay just as well-insulated as your main living room—and they go up in a fraction of the time of a standard brick build.

Explaining hup!

A Faster, Smarter Build for Newbury 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 for state-of-the-art Ultrapanels, our local Newbury installation teams can deliver a fully finished extension up to five times faster than conventional builds. Crucially, because these high-performance panels are significantly thinner than traditional masonry while offering superior insulation, you benefit from a larger internal floor area within the same external footprint—maximising every square inch of your new living space.

For you, this means a remarkably hassle-free home improvement project. Work that might typically cause months of disruption to your daily life is condensed into a matter of days. Furthermore, the hup! process is entirely streamlined: there is no need to hire an external architect. Your dedicated project designer will manage the process from start to finish, navigating 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 structural benefits 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. Furthermore, the system is a much greener choice for Winchester homeowners, as it is 60% more carbon efficient than a traditional brick build, significantly reducing the environmental impact of your home improvement project.

Precision engineering ensures your build is structurally flawless from day one. Every component is manufactured 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 masonry build, offering decades of reliable, high-performance living.

Frequently Asked Questions: hup! in Newbury

Yes. Adding a high-performance, energy-efficient space like a hup! extension is an excellent way to increase your property's market value. In sought-after areas across Berkshire, adding year-round living space significantly enhances your home's appeal to future buyers.

Absolutely. The hup! system is lightweight and specifically designed to easily transform dated conservatories into modern, usable rooms. In many cases, we can utilise your existing base, saving you both time and the cost of pouring new foundations.

Because the advanced Ultrapanels offer superior thermal insulation in a much slimmer profile compared to traditional brick cavity walls, you achieve significantly more usable interior space within the exact same external footprint.

Many hup! extensions fall under Permitted Development rights, meaning full planning permission may not be required. However, if your property is listed or located in a conservation area, our dedicated KJM designers will navigate the West Berkshire Council regulations and handle the paperwork for you.

Costs vary depending on your specific design, dimensions, and chosen finishes. However, because the hup! system is up to five times faster to construct than a traditional brick build, you often save considerably on site labour costs. Contact us for a free, personalised quote.
