The name evokes longing and although the name Oasis is chiefly a play on words, the architecture of the new medical library of the Heinrich Heine University and the University Clinic in Dusseldorf demonstrates clear similarities with a fertile spot in the desert. Not through its form but through its concept; the brief was to design a space for enthusiastic learning; a place of exchange, of innovative teaching and learning and of development. The initial letters of these concepts in German together form the word O.A.S.E. – oasis.The external appearance of the solid structure reflects the library’s specialist topic; it is the architectural expression of the capillary system. This idea is further reflected in the smooth, white façade. Organically shaped glass mosaic tiles linked by glass strips spread like a network over the slender cube and lend the structure its unmistakeable shape. The expressive cubature of the building, the free-flowing forms and fabric of the façade require a fitting response in the design of the interior. The open-plan study and work zones follow the shape of the cores which is then repeated in the waves and amoeba-like forms of the custom-built furniture. The closed, rectangular group study rooms are arranged along the façade walls. A variety of contemporary materials and surfaces such as fair-faced concrete, epoxy resin coatings, various woods, glass and plastic surfaces contribute to a harmonious and inspirational atmosphere in which to study and work.Along with the obligatory library facilities such as the reading and lending areas, work and study rooms, a cafeteria and generous public and exhibition areas are arranged on the eight floors above ground level. The building is crowned by a roof terrace offering an unobstructed view of the university campus.
