The final house for a client who got terminal cancer, to stay for his last period and to leave something for his family. The site is situated in a slope area along Kawazu Vally. The proposal responds to two main subjects: first, the abstractive sense of nature that a man facing to his death would seek for; second, the deliberate balance of architectural design between harmony with surroundings and presence as the final house. The materiality is another key. Controlled aging changes like a Japanese shrine would make his family feel the passage of time and recall memories of the days with him.
