HTL Receives Dual Recognition for Innovation at the Irish Concrete Society Awards 2025
HTL is proud to announce that two of our 3D Construction Printing projects received a High Commendation for Innovation at the Irish Concrete Society Awards 2025. This marks a significant milestone for the adoption of 3DCP in the Irish construction industry.

The Irish Concrete Society Awards are the premier national awards recognising excellence and innovation in the use of concrete in construction across Ireland. Now in their 42nd year, the awards celebrate not just engineering and architectural achievement but also pioneering advances in materials technology, sustainability, and construction innovation. Receiving a commendation in the Innovation category is a strong endorsement of the work HTL is doing to redefine what is possible with concrete construction.
The Grange Close 3D Printed Social Housing Project, developed in collaboration with Louth County Council, LMETB, and Roadstone Ltd, was recognised for its innovation as the first 3DCP social housing project to successfully integrate standard Ready-Mix Concrete in 3D printed housing—an industry-first in Ireland & Europe. As the country’s first 3DCP social housing scheme, Grange Close demonstrates how additive manufacturing can offer a faster, more sustainable, cost-effective approach to housing delivery while meeting all current regulatory and compliance standards.
The jury noted:
“This project must be commended for using 3D Construction Printing in delivering sustainable housing using low-carbon 3D printable concrete. The project is a showcase that will encourage plenty of debate on delivering housing faster in a time when we have a severe housing shortage.”
This year’s awards marked a milestone for the industry, with three categories—the Building Award, International Award, and Sean de Courcy Student Award—all featuring 3DCP projects that received high commendation awards. It’s fantastic to see innovation in concrete construction recognised at this level, highlighting the growing impact and contribution 3D printing can provide in the built environment.
HTL’s second commendation was awarded for the minimass 3DCP Footbridge, an experimental infrastructure project that explores the structural and environmental efficiencies made possible through additive design and fabrication. By reducing material use and accelerating construction timelines, this project is a case study of how 3D printing can enhance infrastructure resilience while contributing to carbon reduction goals.
The jury noted:
"The minimass Footbridge by Harcourt Technologies [and minimass] demonstrates exciting and groundbreaking innovation in 3D-printed concrete beams. The jury was impressed by the company’s commitment to the sustainable future of concrete and the design solutions adopted in this exciting technology."
In mid-2024, HTL.tech partnered with minimass to manufacture and build the world’s first structure to use 3D-printed concrete beams—a 10.8m footbridge in Norfolk, UK. The beams were 3D printed at Roadstone Ltd.’s Belgard plant using Ready-mix concrete, then transported and installed at Constructionarium Ltd in Norfolk, England.

These recognitions affirm HTL’s leadership in driving construction innovation through 3D printing and our ongoing commitment to advancing more sustainable, scalable building solutions in Ireland and beyond.
