hup! walls - a smarter modular house extension system

At the core of every modular house extension we build is the advanced hup! wall system that combines outstanding energy efficiency with rapid installation. Its exceptional versatility allows it to accommodate virtually any design, making it the ideal solution for modular house extensions.

Designed to exceed expectations, hup! walls are transforming the way we build while remaining fully compliant with the latest Building Regulations.

Patented Ultrapanel technology

The Ultrapanel system used within hup! walls combines timber, steel and high-performance insulation in a unique patented design.

By harnessing the strength of steel, the versatility of timber and exceptional thermal efficiency, Ultrapanel creates a robust, highly insulated structure that minimises thermal bridging and delivers outstanding energy performance.

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.

Light and slim

Due to their lightweight nature, hup!'s walls used in a modular house extension can be built on top of an existing base, unlike bricks and mortar which would be too heavy and require a new base entirely. hup! walls are also incredibly light so are easy for our installation teams to handle, contributing to the speed of the build.

Finally, as they are slimmer than a traditionally built wall, hup! walls create a floor space 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.

What drives modular house extension costs?

Because Obsession Design & Build manages design, planning and build as one team, several separate trade handovers are removed from the schedule - a real factor in modular extension costs, since fewer handovers means fewer delays and less risk of price creep.

hup! walls and roofs are manufactured off-site to a fixed specification, so your quote is confirmed upfront and doesn't move once the build starts unlike traditional extensions, where costs often rise once foundations are opened up and unexpected issues appear.
