The building provides 121,000 m2 (1,300,000 sq ft) of office space for the Commerzbank headquarters, including winter gardens and natural lighting and air circulation.

[6] In its immediate neighbourhood are other skyscrapers including the Eurotower (former home of the European Central Bank), the Main Tower, the Silberturm, the Japan Center and the Gallileo.

The result was the world's first so-called ecological skyscraper:[7] besides the use of 'sky-gardens', environmentally friendly technologies were employed to reduce energy required for heating and cooling.

[8] Commerzbank Tower is shaped as a 60-metre (197 ft) wide rounded equilateral triangle with a central, triangular atrium.

In order to eliminate the need of supporting columns in the sky gardens, the building was constructed in steel rather than the conventional (and cheaper) concrete.
