How It Works
Once the design is approved, we begin construction by completing the foundation and then building the superstructure using ICF. Each floor is typically completed within one week, all overseen by a dedicated project manager.
Most homes reach full structure completion within 4–5 weeks, depending on floor systems and project scope. From there, the building can be brought to a weather-tight stage quickly, allowing the next stages of construction to progress without delay.
For this modern home in West Limerick, we used the Castleforms 360 mm ICF block to deliver a durable, energy-efficient structure. Extensive cast-in-situ beams were incorporated to support the expansive corner glazing and other large openings—showcasing the versatility and strength of ICF construction in Ireland.


This bespoke home in Clare was built with the Castleforms 360 mm ICF block system, with the entire main structure and gables completed in one seamless pour. This method ensured superior build quality, improved thermal performance, and long-term durability for the homeowner.
