Modular building offers significant advantages over traditional construction. Here's why more Irish homeowners and developers are choosing prefab homes and modular solutions.
While your site is being prepared, your home is being built in our factory. This parallel process means modular homes can be completed in half the time of traditional construction—often ready in weeks rather than months.
Factory-controlled precision means better insulation, tighter air sealing, and superior thermal performance. All our modular homes are built to A-rated BER standards, reducing energy bills and environmental impact for years to come.
Building in a controlled factory environment eliminates weather delays and allows rigorous quality checks at every stage. The result is consistent, predictable quality that meets exacting standards every time.
No weather delays, no site-based surprises. Factory production allows accurate pricing with genuine fixed-cost contracts. You know exactly what your modular home will cost before committing—no budget overruns.
Factory construction generates up to 90% less waste than traditional building. Materials are precisely measured, off-cuts are recycled, and site disruption is minimised—better for the environment and your neighbours.
Modern modular homes are engineered for longevity. Structural steel frames, quality materials, and precision assembly mean our homes are built to the same standards as traditional construction—with 10-year structural warranties.
From initial enquiry to move-in day, our streamlined process ensures your modular home project is delivered smoothly, efficiently, and to the highest standards.
We discuss your needs, assess your site, and help you choose the right modular solution. We advise on planning requirements and provide a fixed-price quotation for your project.
Your modular home is precision-built in our controlled factory environment. Meanwhile, we prepare your site—foundations, services, and access—so everything's ready for delivery.
Your completed modules are transported to site and craned into position. Our team connects all services, completes external finishes, and ensures everything is weathertight and secure.
Final inspections, snagging, and certification. You receive all documentation, warranties, and operating manuals—then the keys to your beautiful new modular home.
