　The archives comprise architectural design drawings (about 15,000 pieces) and sketch materials (about 4,000 pieces). The drawings mainly include works up to 2000, while the sketch materials include works after 2000. Major works are covered exhaustively and include materials from before the establishment of Atelier Phi (RAS Architecture Institute). Many drawings and sketches for major projects, such as the Kyoto Station Building and New Umeda Sky Building, are left, allowing the views to follow the design process in detail. Many large sketches illustrate the entire elevation surface on paper larger than A0 sheets, showing that the unique design is generated based on through consideration.
　In addition to materials for realized works, there are also many materials for a wide variety of challenging projects, for instance, the Yukotai no Sekai [The World of Porous Body] and Parc de la Villette: Paris International Design Competition, as well as materials for works such as the Modal Space of Consciousness.
