The better way to build a house extension in Portsmouth
There are plenty of reasons hup! is a better way to build a house extension.
No more builds that drag on for months, mess through the house or budgets that keep climbing.
With hup! and our own team at AA Window Services, most of those frustrations are taken out of the picture, giving you a faster, cleaner and more predictable way to extend your home.
Powered by ground-breaking Ultrapanel technology
This patented construction system combines the strength and precision of steel framing with the thermal performance and versatility of timber, making hup! one of the most energy efficient building systems available to homeowners across Portsmouth, Chichester, Worthing and Guildford.
hup! achieves U-values as low as 0.12 to 0.17, a genuinely energy efficient building system that goes well beyond current Building Regulations. For homeowners planning a house extension with AA Window Services, that means a warmer, more comfortable room with lower heating bills, designed around the way you live.
Super strong i-beam structure
hup! wall panels are 68% stronger than a brick wall. As our team fits them, the panels clip together to form a continuous I-beam structure, giving every AA Window Services hup! extension exceptional strength from the ground up.
Rapid connection details
Every hup! component is precision engineered, and the patented connections between walls and roof give an accurate fit every time. That helps eliminate cold spots and keeps your extension warm throughout.
Because the panels clip together on site, our own team can assemble a hup! extension up to five times faster than a traditional build, cutting the time we spend at your home without compromising on quality or performance.
Energy efficient building system
With U-values of 0.17W/m²K for the walls and 0.14 to 0.15W/m²K for the roof, the hup! building system delivers outstanding thermal performance, making every AA Window Services hup! extension one of the most energy efficient ways to extend your home.
A lifespan backed by independent certification
The patented Ultrapanel system has been awarded a minimum 60-year life expectancy by the British Board of Agrément (BBA). This independently verified assessment is based on rigorous testing and evaluation, giving homeowners confidence in the long-term performance and durability of the hup! system.
Tried and tested by UK housebuilders in Portsmouth
Leading UK housebuilders already use the Ultrapanel technology inside every hup! wall to build new homes.
Any material used in a new home has to be approved by the NHBC, which insures new builds. That means hup! has been fully assessed by both the BBA and the NHBC, so homeowners choosing an AA Window Services hup! extension can be confident in its performance and quality.
