Five times faster to build
Watertight before traditional brickwork even begins
A hup! home extension can be built up to five times faster than traditional methods, typically becoming watertight within a week - a timescale that traditionally built extensions rarely achieve.
Complete design flexibility
Create a modern house extension in the style and size that suits your home
Your dream house extension can be designed around the style, size and character of your home. That could be a sleek, contemporary extension with full height glazing and a flat roof on a Portsmouth terrace, or a more traditional design that sits naturally beside a period home in Chichester. Either way, hup! gives you the flexibility to create the look you want.
Choose where you want your windows and doors, select from our range of extension roof styles, and choose an external wall finish that complements your home.
Energy efficient by design
Ultimate thermal performance with hup!
A hup! extension is five times more energy efficient than the average UK home, so your new room stays comfortable and your heating bills stay lower. It’s better for the planet too. hup! walls produce zero waste in manufacture and on site, and are 60% more carbon efficient to make than brick.
High quality finish
AA Window Services creates a perfect build every time with hup!
hup! is manufactured under tightly controlled conditions in a BBA-approved factory, ensuring every modern house extension achieves a precise and consistent finish.
The patented Ultrapanel technology used in hup! is also BBA approved and has been awarded their maximum lifespan rating of at least 60 years, giving you confidence in the quality and longevity of your extension.
One team from design to completion
Complete project management
AA Window Services takes care of the whole project, from the first design through to completion. Our design software means you don’t need to find and coordinate separate architects or structural engineers yourself.
hup! is pre-approved for Building Regulations, which cuts down the paperwork and keeps your project moving. You’ll get clear visualisations, timelines and pricing from the start, so you know exactly what you’re getting and when.
Lightweight
Lightweight advanced building technology
hup! walls are light enough that many conservatory conversions can keep the existing base, which usually isn’t possible when rebuilding with bricks and mortar.
The panels are easy for our own team to lift and carry by hand, so the build moves quickly and your garden isn’t churned up by heavy machinery or piles of materials. Less time on site means less mess and less risk of damage to your lawn, patio and borders.
60% more carbon efficient
Cleaner to manufacture, not just faster to build
hup! is 60% more carbon efficient to manufacture than traditional brick, with zero waste during production and on site. It's a genuine environmental advantage that goes beyond simply building faster, helping to make hup! a more sustainable choice for your house extension.

Independent testing you can check for yourself
hup! has been independently tested for strength, thermal performance, fire resistance and build quality. Rather than taking our word for it, you can download each certificate and read the results before AA Window Services starts work on your extension.
Pre-approved for Building Regulations
Building Regulations sign off is simpler with hup!, because the system is already pre-approved by independent Building Control inspectors Stroma, MFA and Assent. That means less back and forth on your extension, whether you’re in Portsmouth, Chichester, Worthing or Guildford.
