The site is conceived as a landscape in which the building elements are integrally placed, providing optimum security while using landscape as a binding factor. The design of the new building houses the core ECB activities spread over 30 office layers. Due to the spherical shape of the building, each floor plate is shaped differently. A vertical void rises through the core, with staff restaurant facilities forming a three floor, solid heart of this void. A green column wraps the void as a vertical greenhouse contributing to the sustainable environment. The functional integration of the existing Grossmarkthalle is achieved by utilizing this building for the more public aspects of the ECB program, such as press and visitor centre, library, archiving and storage.
