This private house has been designed for a client who wanted his new house, in the Tokyo district of Daikanyama, to reflect both his passion for cars and his work with textiles and fabrics. The external walls are covered in a white Astroturf, treated with an innovative nanotech coating, preventing the surface to attract dirt. The window openings and the recessed car bay gently push the surface of the walls inwards where needed, creating a soft contrast with the rigorous geometry of the building, while the Astroturf surface allows a gradual transition from the solid mass to the surrounding air.
