The two-story, three-bedroom terraced houses, built using a 3D concrete printer, were finalised in just six months and are now set to provide social housing to families who were previously on the Louth County Council housing list.

The homes at Grange Close were constructed with COBOD 3D printing technology, which automates the concrete laying process by following digital blueprints to create cavity walls from scratch, without the need for concrete blocks.

This entire operation took just 12 print days, and the total machine on-site time was 18 working days. Compared to traditional methods, the 3D printing process is 60 percent faster and improves structural integrity, with developers reporting a 35 percent reduction in total construction time, saving valuable time and resources.

Each of the three homes has a gross internal area of 110 square metres and an A2 energy rating, contributing to a sustainable and energy efficient living environment. This initiative was the result of a partnership between Louth County Council, Harcourt Technologies, Roadstone, the Louth & Meath Education & Training Board (LMETB), and Hardcourt Architects.

The Grange Close project demonstrates how innovation, collaboration, and technology can help meet the growing demand for cost effective and sustainable social housing in Ireland. Its success has also been attributed to the involvement of the LMETB, which offered vital training and upskilling to workers in 3D construction printing technology.

These homes will serve as a model for similar initiatives across the country, supplying essential accommodation for local families, a considerable step toward addressing Ireland’s housing challenges.
