Five times faster to build
Watertight before traditional brickwork even begins
A hup! extension can be built up to five times faster than a traditional extension, with the structure typically made watertight within a week - significantly reducing the time your home is exposed to ongoing building work.
Complete design flexibility
Design a modern house extension to complement your home
Your hup! house extension can be tailored to suit the size, style and character of your property. From contemporary extensions with full-height glazing and flat roofs to more traditional designs that blend naturally with the existing house, the system gives you flexibility over how your new space looks and feels.
Choose the position and style of your windows and doors, explore different extension roof styles, and select an external wall finish that works with your home.
Energy efficient by design
Ultimate thermal performance with hup!
A hup! extension is up to five times more energy efficient than the average UK home, helping to reduce heat loss, lower heating costs and create a comfortable living space throughout the year.
The system is also designed with sustainability in mind, producing zero manufacturing waste compared with many traditional building materials.
High quality finish
Built for consistent quality and long-term performance
hup! is manufactured in a BBA-approved factory under carefully controlled conditions, helping to ensure every modern house extension is produced to a consistently high standard.
Its patented Ultrapanel technology is also BBA-approved and has achieved a lifespan rating of at least 60 years, providing long-term reassurance around the strength, quality and durability of your extension.
One team from design to completion
Complete project management
We’ll manage your house extension from the first design ideas through to completion, giving you one clear point of contact throughout the project. Advanced design software removes the need to coordinate architects or structural engineers separately, helping to simplify the process from the outset.
The hup! system is pre-approved for Building Regulations, reducing unnecessary delays and helping your project progress smoothly. Clear visualisations, timescales and pricing are provided before work begins, so you know what to expect from your extension at every stage.
Lightweight
Lightweight advanced building technology
hup! walls are lightweight enough to allow many conservatory conversions to make use of the existing base, something that isn't usually possible when rebuilding with traditional bricks and mortar.
The lightweight panels used in the hup! system can be easily lifted and carried by our installation teams, helping to speed up the build while minimising disruption to your garden. With materials spending less time on site, your garden is protected from unnecessary damage during the installation process.
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 created during production or on site. This helps reduce the environmental impact of your house extension and makes hup! a more sustainable alternative to traditional building methods.
