Steel Houses

Official Irish Distributor of Unic Rotarex® Steel Houses

Galvanised steel-frame houses, direct from the manufacturer's factory in Romania. From compact starter homes to family houses and duplexes, each structure is factory pre-cut, CE marked and engineered for Ireland's climate and building standards.

Each house is built on a galvanised steel frame, making it fast to erect, durable and low-maintenance. Steel houses like these suit a full-time family residence, a self-build project, or a rental or investment property.

Why choose a Rotarex steel house?

1

Fast, dry build

Factory pre-cut steel frames erect in days, not months, with no wet trades holding up the schedule.

2

Durable steel frame

Galvanised steel structures resist corrosion, are low-maintenance, and are built to last for decades.

3

Family-sized models

From a 54 m² starter home to 4-bedroom family houses and duplexes — a model for every site and budget.

Technology

Engineered for Irish weather

Every Pyramid steel house is built on Unic Rotarex® engineering, refined over hundreds of completed projects across Europe. Ireland's climate brings its own demands — driving rain, strong coastal winds, damp winters — and the galvanised steel frame is designed to handle all of it without warping, rotting, or losing structural integrity over time.

Each wall, roof and floor assembly is engineered as a tested system — insulation, fire protection, soundproofing and corrosion resistance are built in from the start.

External wall build-up: plasterboard, light steel studs with wood insulation, OSB, insulated wall panel, Cedral cladding
External wall. Plasterboard, 100 mm steel studs with wood insulation, 12.5 mm OSB, 100 mm insulated wall panel and Cedral fibre-cement cladding (about 235 mm).
Roof build-up: plasterboard, light steel trusses with spray foam, OSB deck, insulated roof panels
Roof. 250 mm steel trusses with 100 mm spray foam, 18 mm OSB deck and 60 mm insulated steel roof panels.
Ground floor build-up: XPS insulation, radon barrier, concrete slab with mesh, Unilin board, underfloor heating in screed, flooring
Ground floor. 100 mm XPS, radon barrier, 100 mm slab with mesh, 50 mm Unilin board and underfloor heating in 45 mm screed (about 310 mm).
ICF foundation wall on a reinforced strip footing with the insulated floor slab inside
ICF foundation. ICF blocks with a reinforced concrete core on a 600 × 250 mm reinforced strip footing, with the insulated slab inside.
Thermal Resistance

Wall buildups range from a standard 22.5 cm assembly (U = 0.27 W/m²K) up to a high-performance 32.5 cm option (U = 0.13 W/m²K), so you can choose the insulation level that suits your budget and Irish building regulations.

Fire Resistance

Walls are clad with fire-rated plasterboard systems offering 30 to 180 minutes of fire resistance, giving flexibility to meet building control requirements for any room or party wall.

Acoustic Resistance

Sound insulation is achieved with acoustic plasterboard, cork cladding, or fully decoupled double-stud walls between bedrooms, party walls, or duplex units — for quiet, private living spaces.

Structural & Seismic Resistance

The light weight of a steel frame means far lower forces act on the structure during ground movement or storm loading, giving a structural safety margin that heavier masonry builds don't have.

Wind Resistance

Every structure is designed to withstand winds up to 150 km/h as standard — well suited to Ireland's exposed coastal and rural sites — with higher ratings available on request.

Corrosion Resistance

The steel frame is hot-dip galvanised with a 150–275 g/m² zinc coating, engineered for a structural lifespan of up to 98 years. Zinc is self-healing, so minor surface marks from transport or storage resolve on their own once assembled.
