The reinforced concrete building was built in cooperation between the architectural firm Kohl & Kohl and the Parisian architect Jean Nouvel. It contains a suspended center core and the edge between floors to Pendelstützen. The floor plan of the tower is divided into three areas, with an 18 meter mast to the upper end.
Overall, the tower has 43 floors, which can be reached by six elevators, each of which travels at a speed of 5 meters per second.
The glass facade of the building was designed with reflected light in mind. Pictures of the Cologne Cathedral and the skyline of Cologne's Old Town were applied to the glass via screen-printing. Depending on light exposure, different combinations of these images appear on the building.
From the antenna on top of the tower Cologne three FM frequencies are broadcasted mainly for the northern districts of Cologne: 98.6 MHz/0.4 kW WDR 2 Regionalfenster Cologne, 87.6 MHz/0.3 kW WDR Eins Live, and 89.9 MHz/0.03 kW Germany Kultur. Despite the low power levels, the height of the antenna allows all frequencies to transmit to the northern suburbs. In 2002, the Tower of Cologne replaced the former FM transmitter site on the nearby Hansahochaus on Hansaring. The other FM transmitter sites in Cologne are the Telephone Exchange on Sternengasse, the Colonius television tower, and the Pollonius radio tower.
