Wolfgang Winter and Berthold Horbelt have been building houses out of boxes since 1996. In public spaces, sometimes for several days and sometimes for weeks or months, they piled several hundred beverage cases on top of each other, arranging them into concave and convex shapes. The brown, green, and orange boxes, which in normal, everyday life, function as part of a system of exchange, are removed from normal commercial circulation and, along with an unexpected aesthetic quality, take on a new function beyond the aesthetics of commercial goods and the logistics of stockrooms. These box houses function as cinemas, bus stops, or -- as in their contribution to the Sculpture Project in Munster which marked their first international success -- an information pavilion and kiosk. With introductory essays and a dialogue between the artists and Florian Matzner, this book examines their work over the last four years, a mixture of sculpture and architecture which takes on an unexpected aesthetic quality.
