Text in English & German. Johannes Peter Hoelzinger studied architecture at the Stadelschule in Frankfurt am Main from 1954 to 1957. After a residency fellowship at the Deutsche Akademie Villa Massimo in Rome he founded a "planning association for new forms of the environment" in 1965 together with Zero artist Hermann Goepfert, who has since died. One of the most successful results of his work with Goepfert was a new design for the Schlosspark in Karlsruhe on the occasion of the Bundesgartenschau in 1967, which won a major German architectural prize, the Hugo-Haring-Preis. From 1991 until his retirement in 2002 Hoelzinger directed the art and public-space course at the Akademie der bildenden Kunste in Nuremberg. Individualistic and oppositional in comparison to other post-World War II architectural achievements, the design of Hoelzinger's buildings is very distinctive. The playful elements of Postmodernism are as alien to his work as the functionalism of New Building. Because of his association with Hermann Goepfert, Hoelzinger is much more closely connected with the art scene of his time. The integration of art and architecture is a unique feature of his buildings. If we try to assign a category to this "object architecture" (a term he coined himself), we will find less overlap with architecture than with fine art. From the very beginning Hoelzinger saw architecture as an artistic discipline. Light kinetics offered him important new perspectives. Lighting design and the resulting colour changes of white walls play a vital role in his work.

Text in English and German. Linking art and architecture is one of the great Utopias of our century. Art has been released from its traditional bonds and sees itself faced with a world that has made systems independent to the extent that a link between art and building based on the idea of unity is no longer admissible. The collapse of our 'world into pieces' also typifies that situation of the arts looking for new orders. Now artist-architect Johannes Peter Holzinger, in co-operation with artists Eberhard Fiebig, Ottmar Horl/Formalhaut, Leonardo Mosso, Norbert Muller-Everling, Ansgar Nierhoff and Andreas Sobeck, working on the government buildings on the Hardthohe in Bonn, has succeeded in creating 'an avant-garde landmark that shows in the interplay of the arts that the avant-garde can also work positively in a team', as Dieter Ronte, director of the Stadtisches Kunstmuseum Bonn, put it in a contribution to this book. Holzinger links heterogeneous artistic positions in attempting an order of the different. The art in the outer areas of the complex mediates between the surroundings and the buildings. The visual signing system leads further into the centres, which are the same shape, of the existing administrative buildings, and creates some thing that is unmistakable there. The special structures designed by Holzinger, an intermediate form of architecture and landscape developed from the relief, include the earth itself, and in the casino architecture and art combine to form an indissoluble unit.
