Hegau Tower

The Hegau Tower building complex designed by Helmut Jahn comprises an 18-storey high-rise building 67.5 m high and an adjacent low-rise building. Werner Sobek was responsible for the structural engineering of the project. The gross floor area of the two buildings is 14,500 m².

The flat and high-rise building parts, which are independent in their construction, are connected into one unit by a glass facade projecting from both building parts, which significantly reduces their massive appearance. Natural ventilation through supply and exhaust air flaps ensures a pleasant indoor climate.

Chicago AIA Award / CTBUH 10 Year Award finalist

Although the project had to be planned and realised within an extremely tight cost budget, a high architectural quality was achieved and the Hegau Tower won the Chicago AIA Award in 2009. In 2018, the building was a CTBUH 10 Year Award finalist.

The Hegau Tower is the tallest building and has been the new landmark of the town of Singen am Hohentwiel since its completion in 2008.
