In the collection, various objects come together, which were created in the course of the research on the potential of various construction-specific materials. In part, these were only used at the beginning of the last century, such as the Torfoleum, for the insulation of walls, in part, I examined their modern equivalents, especially the polyurethane foam. A material that was experimented with back then and today can be found in almost every new building runs through most objects: the aerated concrete. In a free experimental approach different forms and outgrowths of these materials have arisen in different constellations. The supposed storeroom in the cellar of the house Moholy-Nagy served for a temporary presentation. The "homemade" objects appear as if in a future archive of today's society.
