hup! walls for modular house extensions | Tower Home

Every modular house extension we build in Chester starts with the hup! wall system, combining strong thermal performance with fast installation. It adapts to almost any layout, which makes it a genuinely flexible choice for a modular house extension.

Patented Ultrapanel technology behind the hup! building system

The Ultrapanel system inside every hup! wall brings timber, steel and high-performance insulation together in a unique patented design.

It's this combination, the strength of steel, the versatility of timber and genuinely exceptional thermal efficiency, that creates a robust, highly insulated structure. The result is minimal thermal bridging and outstanding energy performance across the whole extension.

Rapid construction

The rapid clip-fit technology used across hup! walls and roofs means your new extension can be built up to five times faster than a traditional build. Because the system goes together in any weather, a smaller extension can be watertight in just two to three days, with no weather delays or scheduling setbacks holding the project back.

Light and slim

hup! walls are so lightweight that a modular extension can often be built straight on top of an existing base, something that isn't possible with bricks and mortar, where the weight demands a brand new base every time. The panels are also easy for our installation teams to lift and handle, which is another reason the build moves so quickly.

They're slimmer than a traditionally built wall too, giving you 10 to 15% more usable floor space inside the finished extension.

Energy Efficient

hup! walls deliver 6% better energy efficiency than a fully Building Regulation compliant wall, thanks to the generous layer of super-insulation built into every panel.

What drives modular house extension costs?

Tower Home manages design, planning and build as one team, which removes several separate trade handovers from the schedule. That's 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. It's a different picture to a traditional extension, where costs often rise the moment foundations are opened up and unexpected issues appear.

What factors influence modular extension cost?

Size and finish choices tend to matter most for modular extension cost, since the underlying hup! wall panel is one fixed, BBA approved specification regardless of project. Tower Home sets this out clearly at quote stage rather than relying on a single ballpark figure for every modular home extension job.

Are hup! walls covered by any formal approval?

Yes, hup! walls carry BBA approval, and the Ultrapanel technology used is rated for a 60-year lifespan. This gives Chester homeowners an independently assessed performance standard rather than relying solely on standard site workmanship, with consistency guaranteed by the factory manufacturing process itself.

What gives hup! walls their thermal performance?

hup! walls are constructed from a patented combination of timber, steel and insulation, manufactured under controlled factory conditions. This produces a consistent 0.17 wall U-value on every Tower Home project, unaffected by weather conditions during the home extension build.
