The house where the owner's uncle lived for a long time and dated 60 years back, was divided into small spaces with narrow rooms and poor air circulation, but it stood on a privileged site with no adjacent buildings, a rare feature in the metropolitan area of the Japanese capital. The house was enriched with traditional furniture perfectly preserved in the interior and white and green woodwork made by skilled local craftsmen in the exterior. The intervention included the reinforcement of the wooden structure of the house and a well planned and accurate renovation project. The architects' aim was to adapt the house to the new owner's way of life, creating a contemporary, airy and bright living space that would be in tune with the surrounding environment, while preserving and enhancing the wooden structure of the house and its retro furnishings. At the centre of the longitudinal body of the house there is a room that can fully open to the outside. "Kazamado" windows, external sliding walls consisting of white mesh sandwiched between green wooden frames, complete the original white and green color combination of the house and close this internal terrace. The result is a place that can always be arranged differently according to sun, wind, cold or heat, where old and new design contaminate and complement each other.
