Chikei is a Japanese word meaning landform which is an interface between us and the earth. Chikei is a ground to grow such lives as human-beings, plants, animals and insects where Architecture is a method to protect us from them and also provides us to talk to and live with them. Architecture and Chikei often collaborate together to weave context which plays an intermediate role to combine them tightly to connotate their time and space. None of innumerable expressions of Chikei is identical as if they were fingerprints of the earth. Architecture also leaves individual stamps on Chikei as it's proof of dialogue. Though Chikei and Architecture have their own peculiar terrains full of diversity, the way how two of them are related seems rather stereotyped. We usually build buildings on Chikei and under it. It is a pity that Chikei is often flattened automatically and after it's soil refuse is cleared away, architectural story always begins. However we know another intriguing examples such as Kappadocian monastry and Yaotong houses in Loess plateau, where quite an unique space is curved out from Chikei, which becomes Architecture. Architecture and Chikei have immanent quality to become both figure and ground. Chikei once recognized as figure can be drastically switched to be ground if our standpoint changes. And they can merge together by being amalgamated when they become soft in our conceptual process of design. In the case of Kyoto Swimming Pool Complex, the first step of the design was to culculate an expected soil refuse. Since it had to have a fairly large mechanical system that was needed to be built under ground, approximately 90000m3 soil was supposed to be taken away from the site. The required architectural volume was 180000 m3, so that 90000 m3 roux + 180000 m3 meat and vegetables could make 270000 m3 curry, that is fluid medium of half architecture/half land. This fluid medium in the conceptual process can be called ''universal form'' which becomes a source of new Chikei. So we could managed to stop discarding the soil refuse that may have caused another destruction of the nature somewhere else. Chikei is thus delicate object inbetween solid and fluid, that could be a major part of the structure and the form of Architecture. In this exhibition, I will exhibit my various quest for the dialogue between Chikei and Architecture. A series of relief models made of paper and my recent works of architecture is introduced in the gallery that is transformed into a space to represent physical and metaphysical world of Chikei.
