Marienturm is a 155-meter (508 feet) tall high-rise, built in the Financial District during the year 2019. Marienturm belongs to the project Marieninsel, which also contains a 40-meter high office building called Marienforum on Mainzer Landstrasse. The location is a prominent place at Wallanlagen which closes a “gap” between the new high-rise of Credit Suisse and Taunusanlage 11. The city administration hopes to revive the quarters, which have so far been almost empty in the evenings and weekends, in the heart of the city.
Over a total of 57,400 square meters of rental space, we see offices, several stores, restaurants, a gym and a kindergarten. To this end, a publicly accessible square has been erected between Marienturm (38 storeys) and Marienforum (10 storeys). The design of the complex comes from the architectural office of Müller Reimann Architekten and it was developed by Pecan Development.
A reinforced concrete skeleton structure serves as the supporting structure of the Marienturm. This consists of a flat reinforced concrete slab on each floor, reinforced concrete columns that are predominantly arranged on the outside in the floor plan, and four reinforced concrete core areas. These serve for horizontal stiffening and are coupled to one another via the corridor ceilings and beams. In the entrance foyer between the ground floor and 3rd floor, the reinforced concrete supports extend over a height of almost 18 meters. In the upper of the four basement floors, the majority of the high-rise columns are supported with the help of wall-like beams made of reinforced concrete. A combined pile and slab foundation was used as the foundation system.
Numerous companies from the financial and service sectors have their headquarters in the Marienturm. These include tenants such as Goldman Sachs and Bank of America.
Status March 2022: The Marienturm, which is almost fully rented, was sold to the DWS Group for around €800 Million, where it will be incorporated into a real estate fund. DWS is a listed asset manager belonging to Deutsche Bank.
