Public space is currently under siege: pressure to consume, growing surveillance, and ever increasing motor traffic threaten to change the appearance of our cities in a fundamental way. The two artists Folke Köbberling and Martin Kaltwasser have been working on their concept of artistic and aesthetic opposition to these developments since 1998. They suggest alternatives to the consumerist ideology—structural interventions, artistic statements, actions, and theories. The artists use streets, squares, bridges, parks, and interiors as areas in which to operate. The materials used always originate from existing “urban resources”: throw- or giveaway objects and even garbage. Each of their works is therefore founded on communicative and social aspects. At the same time, we are stimulated to emulate, disseminate, and multiply their strategies, since they can be realised with the simplest of materials.

Köbberling & Kaltwasser's book - Hold it! - serves as a summary of the outfit's work so far. In it the authors stress that their role, rather than that of a tradilional architect, is to offer examples of empowerment and the temporary popular appropriation of urban space .. .
