The award-winning project, Grange Close, stood out as a groundbreaking demonstration of how emerging and traditional construction methodologies can be harmoniously integrated. HTL’s approach to this project wasn't just about building—it was about reshaping the way the industry thinks about construction from the ground up.

Pioneering Construction: The Grange Close Project

Commissioned by Louth County Council, the Grange Close project is Ireland’s—and Europe’s—first social housing development built using standard ready-mix concrete (RMC) for 3D construction printing (3DCP). Located on an infill site in Muirhevmore, Dundalk, the project delivered three high-quality, 110 m² terraced homes, achieving significant improvements in speed, sustainability, and quality.

The 3DCP process was executed using COBOD International A/S’s BOD2 printer and implemented by HTL.tech. The project was completed in just 132 working days—35% faster than traditional methods, with the 330 m² superstructure printed in just 18 days, a 60% time saving on superstructure construction.

Integration of Innovation: 3DCP, BIM, and Traditional Methods

What set Grange Close apart was its innovative integration of 3D Concrete Printing (3DCP), traditional construction techniques, prefabricated components, and Building Information Modelling (BIM). This hybrid approach revolutionised the construction lifecycle by combining digital design precision with practical on-site execution.

BIM played a crucial role in enabling real-time collaboration, aligning all project partners on a unified digital platform from design to delivery. It allowed instant updates, visualisation of construction phases, and seamless translation of BIM models into 3D printing instructions, ensuring unmatched precision and reduced error margins.

Materials Innovation and Sustainability

Grange Close broke new ground as the first project in Europe to use standard RMC in 3DCP, through a strategic partnership with Roadstone Ltd. This innovation proves the scalability of 3DCP by integrating with Ireland’s existing concrete supply chain. The use of RMC helped minimise material waste, enhance sustainability, and reduce transport emissions.

HTL also became the first company globally to pass an audit of a 3DCP project under the ISO/ASTM 52939:2023 standard—a globally recognised quality assurance protocol for additive manufacturing in construction. The audit was led by Qualified AM GmbH, under the guidance of standards expert Gregor Reischle.

Empowering the Future of Construction

HTL worked closely with Louth and Meath Education and Training Board (LMETB) and Future Cast to deliver a collaborative training programme, introducing students and tradespeople to cutting-edge digital construction methods. This investment in skills development is part of HTL’s broader mission to shape a resilient, tech-enabled future for the Irish construction workforce.

Collaborative Excellence

The Grange Close success story was built on strong partnerships. HTL is deeply grateful to the following project partners for their dedication and expertise:

Louth County Council, Roadstone Ltd, Louth and Meath Education and Training Board, Harcourt Architects, GARLAND, VCL Consultants, Creagh Concrete, Munster Windows & Joinery, Tradecraft, Future Cast, MGM Partnership, CSD Engineering Limited, B&C Contractors Ltd., McCann FitzGerald LLP

This collective effort exemplified how government, industry, and education can work together to deliver innovative and impactful housing solutions for communities in need.
