Sand. The Transformation of Berlin is a unique documentary project about a city in transition. Many of the few remaining inner-city wastelands and temporarily used spaces that were characteristic of Berlin for so long have disappeared in recent years and given way to new buildings. The photographic project explores this transformation process. The photographs from 2017 – 2022 show Berlin construction sites at a moment when the old has just been cleared away and before the new is erected. They capture vistas in the urban fabric that will soon be gone. It is also the moment when it is revealed what Berlin is built on: sand. In his photographic projects, Michael Lange explores aspects of the city and architecture. A focus of his work is the transformation of the Berlin cityscape.
