The best room in the house
isn’t in the house.
A steel-framed Superstrux™ garden room — made to your millimetre in a British factory, insulated for every season, and up in days. Scroll to step inside one at dusk.
Open an entire wall.
Fold the doors back and the garden becomes part of the room. The Superstrux™ steel frame is stronger and straighter than timber — so your bifolds can run up to three metres wide, in White or Anthracite. Prefer French or single doors? Those too.
Never paint it. Ever.
Crisp vertical-line composite wraps all four walls. No rot, no warping, no ladder every spring — choose Anthracite, Slate Grey or Ivory and it stays this sharp, year after year.
A real room. Not a posh shed.
Smooth plaster-and-paint walls and ceiling, sockets and lighting where you want them — and an insulated shell of 80mm Kingspan/Celotex plus 100mm Rockwool. Office-warm in January. Cool in July.
Let the sky in.
Crown the flat roof with up to two glazed roof lanterns, sealed under an Armour Plan covering with full guttering. Daylight from above, weatherproof from every angle.
Instant guide price · No commitment
Engineered, not thrown up.
Every garden room is a Superstrux™ System 7 building — a British-made steel frame wrapped in seven engineered layers, cut to your exact size in a UK factory and assembled in your garden in days.
-
British steel frame
Superstrux™ System 7 — seven engineered layers on a 100% UK-manufactured steel skeleton. Millimetre-accurate, stronger and straighter than timber, and 100% recyclable.
-
Aluminium bifold doors
Wide-span openings the steel frame carries with ease — up to 3m of folding glass in White or Anthracite. French and single doors available too.
-
Vertical composite cladding
Three colourways — Anthracite, Slate Grey and Ivory — wrapped around all four walls. It never needs painting, and it never rots.
-
Glazed roof lanterns
Up to two lanterns (600–3000mm) in White or Anthracite flood the room with natural light through the flat roof.
-
Insulated shell
80mm Kingspan/Celotex external plus 100mm Rockwool internal insulation — so the room works in every month with a vowel in it. And the rest.
Up in days
Prefabricated panels assemble fast — no wet trades, no weather delays, no months of mess.
Warm all year round
Insulation wraps all four walls — 80mm Kingspan/Celotex outside, 100mm Rockwool inside. A January office, not a summer house.
Zero-maintenance skin
Composite cladding and an Armour Plan flat roof shrug off British weather, decade after decade.
Engineered to UK Building Regulations
Designed to meet and exceed the standards — safe, sound and future-proof.
Design every detail. Watch the price follow.
