Technology & Products

Key Products

3D-printed homes (serendix10, serendix50/Fujitsubo, serendix5 series kits from ¥3.3M), construction 3D printing for railway stations/infra (JR Hatsushima), disaster temporary/reconstruction housing, digital construction data / robotics platform for multi-site printing.

Technological Advantage

Utilizes a 'Consortium' business model with 280+ partner companies to share R&D and supply chain risks, alongside a proprietary digital construction data platform that allows houses to be 'printed' at various global or domestic sites using local 3D printers.

Differentiation

Value Proposition

Eliminates the need for 30-year housing loans by offering high-quality, earthquake-resistant, and high-insulation homes starting at approximately 3.3 to 5.5 million JPY, built with unprecedented speed through robotic automation.

How They Differentiate

Serendix differentiates through its 'Consortium Model' (300+ partner companies) and a 'Data-Only' export strategy. Unlike competitors focused on custom architecture, Serendix prioritizes extreme speed (under 24 hours) and standardization to achieve a 'house for the price of a car' (3.3M - 5.5M JPY), specifically targeting a mortgage-free lifestyle.
