Öffentliche Aussichtsplattform KölnTriangle

At a height of 103.2 metres, the public panorama terrace on the KölnTriangle high-rise building offers a fantastic view of the cathedral, the city and the surrounding area. The idea of the public viewing platform was already presented in the architectural competition in 1992 but only then realized for the completion of the high-rise in 2006. This makes the KölnTriangle one of the very few high-rise buildings in Germany whose roof is available to the public.

The architects have now been commissioned to further develop the highly frequented platform and to make it more attractive for 'longer' stays. A gastronomic offer with serving counters will soon invite tourists and citizens of the city to enjoy the view of their city while enjoying a water or a "Kölsch" (beer). The new shading of the inner core of the tower through a textile sun protection, which lies within a steel construction, guarantees a pleasant stay on sunny days. The integrated lighting concept provides an attractive atmosphere in the evening hours.

A special challenge in the implementation was the transport of the arched steel construction to the viewing platform on the 29th floor. Despite the segmentation, the steel elements could not be transported over the interior of the high-rise building and were therefore flown by helicopter from the ground to a height of over a hundred meters.
