New ECB Renderings
At a height of around 185 metres, the double tower, with its polygonal shape and east-west orientation, has a striking profile that is visible from all important reference points in Frankfurt’s city centre, as well as from the river Main. Thanks to its form and presence, the double tower will become a characteristic feature of the Frankfurt skyline.
The imposing form of the Grossmarkthalle, which so strongly characterises Frankfurt’s skyline and the north bank of the river Main, unites with the vertical profile of the towers to form a significant ensemble that considers both the local urban design environment and the general urban spatial context, thus creating a tension between Frankfurt’s banking district and the Ostend area. By concentrating the ECB’s functions in the Grossmarkthalle, the south side of the premises, facing the Main, can be largely kept free of construction. The prominent view of the south side of the hall from the Main embankment with the clearly visible profile of the high-rise emphasises its special position.
The atrium between the office towers becomes a “vertical city”. Through platforms we are creating spaces, plazas and pathways between the towers, just as they exist in a city. The connecting and transferring levels divide the atrium horizontally into three sections of different sizes, with heights ranging from around 45 to 70 metres. These connecting platforms, bridges, ramps and stairs form a network of links between the office
towers. They create short paths between the individual office floors in each tower and thus enable larger, interconnected usable office spaces on one or more floors in both towers, thereby also promoting informal communication.
Our design reinforces the Grossmarkthalle’s existing potential as an “urban foyer” housing a conference and visitor centre, as well as a library and restaurant, through the incorporation of a building for the press centre which traverses the structure of the Grossmarkthalle. This so-called entrance building, in which ECB press conferences will be held, occupies a special position in content, form and space and thereby marks the entrance to the ECB. Since the western parts of the Grossmarkthalle were reconstructed after being destroyed during the Second World War and do not, therefore, represent part of the substance of the original building – even in the way they are constructed – we propose, as agreed with the historic preservation authority, that the incision for the new entrance to the ECB be in this part of the hall.
As before, the required new facilities are being placed in the spacious interior of the hall as independent building structures (the “house within a house” concept). However, in a revision vis-à-vis the Optimisation Phase, we consider it necessary to express the functional and spatial independence of the other two large functional areas in the Grossmarkthalle in a more pronounced manner. The building structures, which are at diagonal angles to the Grossmarkthalle, allow the hall to be experienced along dynamic
spatial sequences – and this not only in the public areas of the hall’s ground floor, but also on the upper levels, which, with their conference and restaurant facilities, are largely reserved for employees of the ECB. The restaurant structure, as a visible sign of the new functional areas in the hall, generously orients the employee restaurant and terrace towards the Main in the south. Through this strategy we are realising a distinctive entrance on the one hand, and a functional urban connection to the neighbouring Ostend district on the other. The entrance structure and restaurant thereby become visible signs of the new content of the Grossmarkthalle and visually merge with the city, the district and the river Main.
