This text is follows the Austrian architect, Rudiger Lainer, whose buildings are characterized by the harmonization of systemic economy and lively individuality. Alongside several celebrated buildings, it also contains numerous projects, competition entries and texts written by Lainer. Lainer succeeds in combining systemic economy and a lively indiviuality in an architecturally productive relationship. The social and cuultural requirements of future inhabitants form the very basis for the identity of the building. His concepts and forms are playful and easy, avoiding any fashionable severity which through repetition becomes banal.
