She creates sculptural work – not only limited to painting – which could be described as multimedia and multidimensional. Thus, her works become installations. A representation of space turned into a stage set as if it were a theatre play; a painting that refuses to comply with the architecture of the building and the spatial limitation imposed by it. In this way, these works, that are only temporarily made available through an exhibition, trigger the sense of urgency to visit them since their very existence is timebound. In this respect, Katharina Grosse's painting/works might also be compared to a spectacle/performance in which the visitor becomes its main actor/actress.

All her work is site-specific, and one of many examples is the exhibition "It Wasn't Us" in the Hamburger Bahnhof Museum in Berlin. For this site-specific painting, Katharina Grosse defied, as ever, the constraints of the building with a grand gesture and bright colours. "I paint myself out of the building", is how the artist describes her work. In a process that lasts for weeks, she creates an expansive image that spreads from the exhibition space out into the public space and even spills out onto the grounds behind the museum in order to finally land on the façade of the adjacent buildings.
