Superstrux™ System 7 is a next-generation solution for building garden rooms – a freestanding, flat-roof shell that goes up faster, smarter, and more cost-effectively than a traditional build.
Unlike a traditional garden room that takes weeks and is often delayed by weather, a Superstrux™ System 7 structure reaches a waterproof stage in just 24hrs.
No sales calls and no waiting for a survey. Choose your size, see the price instantly, and know exactly what it costs before you commit.
A Superstrux™ System 7 garden room is assembled in days, unlike traditional builds which take weeks and are delayed by weather.
Take the shell flat-packed and erect it yourself, or have our team install it for you — watertight within 24 hours.
A high-performance garden office, studio, or gym installed in days, not months—saving money, reducing disruption, and delivering precision-built results.
Shell erected in just one day—no weeks of groundwork and bricklaying at the bottom of the garden. Weather-tight almost immediately, with minimal disruption to the household.
#1 Reason Homeowners Choose UsFixed pricing with fewer unknowns. Reduced labour costs, less risk of delays, and no lengthy scaffold hire. No budget creep.
Lower Overall CostA four-wall, flat-roof structure that stands on its own — no need to tie into the house. Ideal for a garden office, studio, gym, or treatment room.
Millimetre-accurate fabrication delivers better fit, better finish, and faster snag-free completion with factory-engineered quality control.
Superstrux™ erection isn't weather-dependent. No waiting for mortar to cure, less downtime from rain or cold. Ideal for UK climate.
Excellent insulation and airtight construction mean lower heating bills — a garden room that's comfortable to use all year round, not just in summer.
Lighter than traditional masonry—often avoids costly foundation upgrades. Perfect for rear gardens, tight access, and urban sites where machinery can't reach.
Superstrux™ is 100% recyclable with less site waste and lower embodied carbon than masonry. Modern Method of Construction (MMC).
Works with render, timber, or cladding, and any size from 2m x 2m up to 10m x 6m. Matches your garden—doesn't look like a shed.
No mortar to cure and no drying-out period. Once the garden room is finished you can move furniture straight in and start using the space that week.
A Superstrux™ garden room uses the same next-generation System 7 shell as our house extensions — built freestanding, with four walls and a flat roof, so it drops into any garden.
This innovative method cuts material and labour costs, and each garden room can be finished with render, timber, or cladding to suit the garden it sits in.
