The work "Schlafquartier – Obdachlosigkeit in deutschen Großstädten" deals with rough sleepers in large German cities (Berlin, Hamburg, Cologne, Frankfurt, Leipzig, Munich). The result is a systematic photographic and cartographic representation of the places where the ever-increasing homelessness in the cities is noticeable and recurring. In addition to a total of 40 photos, there are detailed and large-format city maps of each of the 6 cities, 18 essays on local events and background information about homelessness, supplemented by statistics and direct quotes from homeless persons.
