Serendix signs Japan-first disaster 3D-printed housing supply pact with Sukagawa City

Serendix, the Nishinomiya-based 3D-printed housing manufacturer, has signed a disaster-time housing supply agreement with Sukagawa City in Fukushima Prefecture. Under the pact, Serendix will preferentially supply homes built with construction 3D printers when emergencies require rapid shelter. Major structural parts are produced in a factory, transported to site, and assembled in as little as 24 hours, at lower cost and shorter schedules than conventional housing. Officials described the arrangement as Japan's first municipal disaster agreement dedicated to 3D-printed housing supply, with the signing held at Sukagawa City Hall on July 28.

The deal extends a deployment trail that already includes eight 3D-printed homes delivered to Suzu City, Ishikawa, after the 2024 Noto Peninsula earthquake. For construction AM, that field reference carries more weight than a technology demo: disaster logistics reward proven lead time, transportability, and assembly discipline over printer theater. Preferential municipal supply also moves Serendix from one-off project sales toward embedded public-sector demand, which can stabilize utilization if inventory, factory throughput, and multi-city call-up rules are defined up front.

Serendix has stacked housing references since completing Japan's first 3D-printed house, serendix10, in March 2022, and later co-built a 3D-printed station house at Hatsushima Station with the JR West Group in March 2025. The Sukagawa pact is less a product launch than a service-capacity claim: construction 3D printing becomes reliable emergency infrastructure only when fleet output is repeatable under simultaneous municipal demand.
