Patented hup! walls for modular house extensions

Discover how patented hup! walls outperform traditional masonry for modular house extensions across Worcester, Kidderminster, and Worcestershire

The wall is where every great extension begins. 5 Star hup! uses patented hup! walls across all modular house extension projects in Worcester and Worcestershire. Built from a patented combination of timber, steel and insulation, each wall panel delivers outstanding thermal performance, structural integrity, and faster build times that traditional brickwork simply cannot replicate.

hup! walls powered by patented Ultrapanel technology

The Ultrapanels used in hup! walls is built from a patented combination of timber, steel and insulation.

This unique construction brings together the strength of steel and timber with high thermal performance, creating a strong, energy-efficient structure with no cold bridging.

Rapid construction

The rapid clip-fit technology used in hup! walls and roofs mean that your new hup! extension can be built up to five times faster than a traditional build. Built in any weather a small extension could be built and watertight in 2-3 days without any weather or scheduling delays.

Lightweight and slim

Due to their lightweight nature, hup! walls can often be built on top of an existing conservatory base, unlike bricks and mortar which would be too heavy and require a new base.

hup! walls are also incredibly light so are easy for us to handle, contributing to the speed of the build. Finally, as they are slimmer than a traditionally built wall, hup! walls can provide an internal floorspace that is 10-15% larger than one with brick walls.

Energy Efficient

hup! walls are 6% more energy efficient than a fully Building Regulation compliant wall thanks to the large proportion of super-insulation in the panels.

Thermal performance that matches the space efficiency

For planning-conscious homeowners whose permitted development allowance defines the maximum external dimensions of their project, hup! walls mean more room to live in within the boundary that planning permits. The thermal performance of the hup! wall system is entirely uncompromised by its reduced profile too, hup! is five times more energy efficient than the average UK home. The result is a living space that is comfortable all year round, regardless of the aspect or exposure of your Worcestershire property.

Built in a factory, installed with precision

Unlike traditional extensions where walls are built brick by brick on site, patented hup! walls are manufactured under controlled conditions before delivery. This removes weather dependency, reduces on-site waste to zero, and means your modular house extension can be watertight in less than a week. For Worcester homeowners, that is a significant advantage in terms of both speed and predictability.

Up to 15% more floorspace

Internal floor space is one of the most valuable assets in any home, and the difference between a spacious kitchen and a restrictive one often comes down to centimetres rather than metres.

Slimline hup! walls reduce overall wall thickness compared to traditional brick, giving homeowners across Worcester, Malvern, Bromsgrove and Droitwich more usable floor space within the same footprint.
