Why choose 5 Star hup!

Design without compromise. A 5 Star hup! gives you complete freedom over the size, layout and appearance of your new extension. Position windows and doors exactly where you want them, choose from five distinct roof options with glazing placed to suit your space, and finish the exterior in a style that seamlessly matches your home. With slimmer, high-performance walls, you’ll also gain up to 10–15% more usable floor space compared to a traditional build.

Every hup! system installed by 5 Star is precision-manufactured in a BBA-approved facility, ensuring consistent quality and performance. The patented Ultrapanel technology also holds BBA approval and carries a certified lifespan of at least 60 years — the highest rating available. Using advanced design and manufacturing software, each component is produced to exact specifications, allowing everything to fit seamlessly on site for a fast, accurate and flawless build.

When you install a hup! extension with 5 Star, the planning requirements are no different to those of a traditional extension or conservatory. Each project is assessed individually, and our experienced team will guide you through what applies to your property.

In many cases, hup! installations fall within Permitted Development rights, meaning formal Planning Permission may not be necessary. If approval is required, 5 Star will advise you clearly and help you understand the next steps, ensuring the process is straightforward and stress-free.
