Fantastic city panorama at dizzying heights Object Tower 185, Frankfurt a. M. / Germany Principal CA IMMO Deutschland, Frankfurt a. M. / Germany Architects Prof. Christoph Mäckler Architekten, Frankfurt a. M. / Germany At 200 metres high, the prominent Tower 185 in Frankfurt am Main is currently the fourth-tallest building in Germany. Its two sustainability certificates make the office tower a model project. An important factor in the building s sustainable design is its technical sun shading system. In Tower 185, WAREMA products achieve energy efficiency, visual comfort and a pleasant working environment. Gross floor area 129.000 m 2 Completion Early 2012 Tower 185 is the icon of the nascent Europaviertel district, located on the grounds of the former freight yard in the triangle between the central train station, exhibition centre and financial district. The asymmetrical building complex consists of the 50-storey tower and a six-storey base. While designing the structure, the Prof. Christoph Mäckler Architekten architectural office drew inspiration from the immediate surroundings. The base building, for example, in- corporates structural elements from the neighbourhood: light-coloured natural stone and sloped, slate-covered roofs emphasise the urban appeal through the repetition of shapes and materials. The city layout also had an influence on the arrangement and orientation of the building s parts. 2 3
