Stronger, warmer
and faster to build.
The modular wall panels are the heart of the entire system. Built from a patented combination of timber, steel and super-insulation, they are 68% stronger than a brick wall, five times more energy efficient than the average UK home — and clip together in any weather in a fraction of the time traditional construction takes.
Not timber frame.
Not steel. Both.
The Ultrapanels used in the modular wall system are constructed from a patented combination of timber, steel and insulation. This unique hybrid structure eliminates the weaknesses of each material individually — combining them into a super-strong, thermally efficient wall with no cold bridging.
It's a fundamentally different approach to construction, and the numbers prove it.
Watertight in
2–3 days.
The rapid clip-fit technology used in the modular wall panels means the entire structure can be built up to five times faster than a traditional brick build. Panels connect with millimetre precision — no cement, no waiting for mortar to set, no weather delays.
A small extension can be built and watertight within 2–3 days. Our certified Scottish team handles everything on site, with minimal noise and disruption to your home and neighbours.
- Millimetre-precise clip-fit connections
- No cement required on site
- Buildable in any weather — no delays
- Watertight in 2–3 days
- Minimal noise and disruption
- Compatible with existing conservatory bases
Every advantage.
No compromises.
A+ Energy Efficiency
U-Values of between 0.12 and 0.17 W/m²K — significantly exceeding Building Regulation requirements and delivering five times the thermal performance of the average UK home. Lower bills. More comfort. Every season.
Super-Strong Structure
The collective force of the interlocked panels creates a continuous i-beam structure throughout the extension — making the finished build 68% stronger than a comparable brick wall.
Slim Walls, More Space
Modular walls are significantly slimmer than traditional brick walls. The result is a floor area 10–15% larger than an equivalent build using traditional methods — real extra space with no extra footprint.
Any External Finish
The panels accept virtually any external finish — brick, render, stone, timber cladding or painted. Your extension will match your home perfectly, whatever its style or age.
No Cold Bridging
Millimetre precision engineering ensures perfect connections throughout with no cold spots — maintaining thermal performance at every junction and eliminating the condensation problems common in traditional builds.
Independently Accredited
The modular wall system has been independently assessed and accredited by the BBA and NHBC — the same bodies that certify materials used in new-build homes across the UK.

leading architects.
"This system is an absolute game changer — getting watertight in two or three days, it's the future of home extensions."
— Laura Jane Clark, Architect, BBC's Your Home Made Perfect
The modular wall system has been adopted by leading UK housebuilders to construct new homes — meaning it has been through the most rigorous quality, safety and thermal assessments in the industry.

Common
questions answered.
Are modular walls stronger than brick?
Yes — the collective force of the interlocked Ultrapanel system creates a continuous i-beam structure that is 68% stronger than a comparable brick wall.
Do modular walls comply with Building Regulations?
Yes — the wall system is fully Building Regulation compliant and pre-approved by several independent Approved Inspectors. U-Values have been independently verified by Elmhurst Energy.
What external finishes are available?
The panels are compatible with virtually any external finish — including brick slip, render, stone, timber cladding and painted finishes. Your installer will advise on what works best for your home.
Can the walls be built on an existing conservatory base?
Yes — one of the key advantages of the lightweight modular wall panels is that they can be installed on most existing conservatory bases without new foundations, making conservatory conversions significantly faster and more cost-effective.
