Serendix finished Japan’s first 3D-printed house in under 23 hours and 12 minutes. The Japanese business initially revealed the sphere — a 3D-printed housing concept — in early 2021, claiming it could be built in a day for less than 3 million yen (about $25.500 USD). The firm has achieved its aim one year later.
The skeleton weighed around 20 tons and was assembled in three hours, according to the official announcement. ‘Housing construction, including waterproofing and openings, was finished in under 23 hours and 12 minutes. As a consequence, we met Serendix’s development target of building a house in 24 hours.’
More about the Development
A futuristic reinformed concrete frame weighing 20 tons. Serendix is Japan’s first housing company to produce a 3D-printed house. It’s called the sphere, and it has a 20-metric-ton reinforced concrete structure and a footprint of less than 10m2, making it exempt from Japan’s construction restrictions. The rib-reinforced double structure meets European thermal insulation criteria, and experts have ensured that it also meets Japanese seismic performance norms.
The sphere was created by Japanese architect Masayuki Sono, who won the NASA 2015 3D housing competition, and was built at the hyakunen jutaku factory for the first time. The advantages of a design that can be created in less than 24 hours go beyond time and cost savings. In fact, in the case of a large-scale natural disaster, the firm deployed off-the-grid technologies to deliver immediate assistance and comfort to those in need.
