COBOD’s BOD2 3D construction printer was used to complete the first 3D-printed social housing project in just 132 days. Located in Dublin, Ireland, ‘Grange Close’ is a three-unit terraced social housing project with a total floor space of 330 m2 (3,552 ft2), consisting of 3 apartments spanning 110 m2 (1,184 ft2) each.
As mentioned previously, the entire project was completed in just 132 working days, including the initial site preparation to the handover of keys. When compared to the 203 days typically required for traditional construction methods, this represents a 35% reduction in build time, with approximately 50% of the time savings coming directly from 3D printing the wall system alone.

HTL.tech is extremely proud to be the first company in Europe to build a structure that complies with the rigorous new I.S. EN ISO/ASTM 52939:2023 additive manufacturing standard, representing a significant advancement in additive construction. The COBOD BOD2 3D printer was crucial in this accomplishment, enabling us to complete the Grange Close Social Housing Scheme 35% faster than traditional methods. The BOD2 printer’s precision and efficiency, combined with complementary Modern Methods of Construction (MMC) technologies, allowed us to establish new industry standards and offer an effective means to produce high-quality, sustainable housing at an accelerated rate,” said Justin Kinsella, Director of HTl.tech.
