The property of the G75 Office Building on Gereonswall 75 in Cologne is one of the typical Cologne 'interplaces'. It used to be farm land in the Middle Ages as part of the 'Kümpchenshof'. Since the Second World War it was used as a public parking lot. Strictly the new office building does not interact with its surroundings, as its own spatial characteristics and logic develops internally. The first floor is free of office use and is available to public use. The upper floors are used by the office of Schilling-Architekten.
