Architecture - A highlight in the skyline
The clear, minimalist architecture of the MAIN TOWER results from a fascinating synthesis of the basic circle and square shapes. This independent combination of curves and edges gives it an unmistakable appearance that blends harmoniously into the cityscape and skyline. Its 200-metre high round tower, the 170-metre high square tower and the base section adapted to the height of the previous building create a strong association with neighbouring high-rise buildings and ensure that the MAIN TOWER blends perfectly into its direct surroundings. The extraordinary structural aesthetics also convinced experts: the IMMOBILIEN AWARD 2001 was conferred on the building at the 2001 CIMMIT convention.
As an environmentally-friendly, resource-saving and sustainable building, the MAIN TOWER also sets new standards: In September 2011, it became the first existing building in Germany to achieve certification with the coveted LEED Gold status. Since October 2016 it has also been awarded LEED PLATINUM status.
