The new building for the European Central Bank is located on the site of the listed Großmarkthalle in the East of Frankfurt.
The striking 180 m high double towers are unified to an entity by a full height glass atrium. The listed market hall ”Großmarkthalle” experienced a restoration process as part of its integration within the construction of the new ECB towers. The impressive 220 m long and 52 m wide brick building from Martin Elsaesser houses the lobby, conference rooms and the press centre. A "clamp" cuts the roof zone diagonally in order to define the new main entrance in the North and provides a transfer to the tower in the South.
The load-bearing exterior walls of the double towers transfer the vertical loads into the raft-pile foundation. The concrete cores provide lateral stability to the individual towers and resist the horizontal forces from the partially tilted façades. The numerous ramps, bridges and slabs connecting both towers create an entirely effective structural system.
The two solid towers of the double highrise are structurally linked via large steel struts and reinforced concrete slabs across the 20m wide atrium space. The atrium façades on the East- and West side span between the two towers and create a glass surface connecting to the glazed roof.
The East façade is approximately 42 m wide at its base and 21 m at the top. Due to the twisted geometry of the towers, a part of the East façade is inclined. The West façade spans approximately 23.5 m at its top and bottom.
The free-standing steel structure of the atrium façades is designed as a fully welded grid, which is fixed horizontally and vertically sliding at the towers. Via a kink within the two façades horizontal, differential movement of the two towers can be accommodated. The self weight of the whole façade is transferred to the groundfloor slab and a downstand beam below. In addition, windpins, which are connected to the towers, prevent excessive deformations of the façades in case of wind load.

'Fluid Bodies'3 years ago, Bollinger+Grohmann joined the artistic research project ‘Fluid Bodies’ under the direction of Klaus Bollinger at the University of Applied Arts Vienna. The research project aimed to challenge the conventional formwork concepts about concrete and the pre-existing assumptions about the material and its abilities. Models and objects in various sizes where produced with a series of methods spanning over many disciplines such as architecture, fashion design, structural design and sculpture.
To celebrate the end of the project, the research team opens the doors to the public for a one-day exhibition at the Wotruba-Atelier in Vienna where they completed their last workshop.

2nd place in competition: NICE HQ, Oderzo"Nice Headquarter" is designed as a high-tech building. The key characteristics are the transparency and lightness of the façades and the roof, which is a monolithic element that opens and closes according to the sun position and weather conditions. It provides a dynamic and flexible space for the inner courtyard.
A set of integrated lights enhances the building's perception at night, maintaining a high level of visibility and a sober profile blending with the surrounding environment.
