427 Departament

427 Department is an architecture office dedicated to designing complete houses with clarity, balance and intention. Operating between Tokyo and Singapore, the studio works with a process guided by observation, natural light and structural precision. Every project begins quietly, understanding how the space should exist and evolve over time.

The studio operates where structure meets atmosphere, creating homes that feel human, functional and grounded. Materials, proportion and rhythm define each decision. The result is architecture without excess, built to support daily life and allow the house to age with honesty.

427 Department treats every project as a lasting system. Spaces are designed to breathe, adapt and remain relevant through use and time. More than creating houses, the studio builds environments shaped by silence, proportion and calm presence.
