A housing project in Ireland uses 3D printing technology to build three modern 330 m² homes in record time, reducing traditional construction times by 35% and providing affordable social housing.
Located in Louth, in the east of Ireland, the Grange Close project consists of three terraced housing units. Each house has two floors and a living area of 110 m², which guarantees enough space for families looking for comfort and functionality. In total, the development occupies 330 m² and was designed to serve social housing residents.
What makes this project extraordinary is not just its proposal, but the execution time. From start to finish, Grange Close was completed in just 132 working days, with the main structure printed in an incredible 12 days. This represents a 35% reduction in construction time compared to traditional methods, highlighting the efficiency of 3D technology.
Why is 3D printing the future of construction?
Half of the time savings came directly from 3D printing the walls. This is possible because the technology allows us to create precise structures that are ready to integrate other components, such as electrical and flooring systems. The result? Less manual work and lower labor costs.

3D printing uses materials efficiently, generating less waste. Furthermore, with technological adjustments, future projects can be completed in up to nine days, making the process even faster and more sustainable.
How does a 3D printer work in construction?
Grange Close was built using COBOD’s BOD2 printer. This machine extrudes a cement-like mixture layer by layer, creating the building’s structure with millimetre precision. Each stage of the project is guided by a digital model, which reduces errors and speeds up execution.
After the walls are printed, human builders finish the project by installing roofing, electrical systems, and interior finishes. This combination of technology and human labor results in homes that are modern and functional, indistinguishable from traditional construction.
Benefits of the Grange Close Project to the Community
The main objective of the project is to provide quality housing at affordable prices. The houses will be rented to low-income families, promoting social inclusion and improving quality of life.
By reducing costs and timelines, 3D printing could become a viable solution to housing crises around the world. Projects like Grange Close are an example of what can be done to address global challenges such as homelessness.
3D printing in architecture
Imagine a world where skyscrapers or entire residential complexes could be built in a matter of weeks. That’s the promise of 3D printing technology. With constant innovation, it’s getting closer and closer to making ambitious projects a reality.
As technology evolves, production costs continue to fall while building quality increases. This opens doors for architects and engineers. explore new possibilities, creating bolder and more accessible projects.
Houses could be loaned out on a loan basis, depending on the resident's profile.
