ONE (former project name: Tower One) is a high-rise building completed in summer 2022 near the trade fair grounds at the entrance to the Europaviertel. The design is by MEURER ARCHITEKTUR + STADTPLANUNG, and the project development was carried out by CA Immo. The development of the high-rise building primarily followed two guidelines: on the one hand, the design of the ONE should resemble a one, i.e. the building name, and thus have a minimalist conciseness with regard to the brand logo. Second, the skyscraper sets standards in terms of efficiency and sustainability, both in construction and operation.

ONE was developed as a polygonal slice with a striking head formation in the direction of the main axis. The annex building has as its main function a parking garage with 470 parking spaces and was added to the high-rise building as an urban space-forming addition. Together, the two buildings form two trapezoidal city squares, which open up to the city in a funnel shape.

Tower ONE is a mixed use office and hotel skyscraper

Office Tower With a Hotel

The upper section of the skyscraper contains office space. The lower floors are occupied by NH Hotel Group featuring a hotel with restaurant and conference areas. The hotel comprises a shared lobby, co-working areas, and a skybar with surrounding outside areas at 185 meters (607 feet). The lobby also features a café and cocktail bar.

Overview of Usages

Skybar featuring open-air access: 47th floor
Offices: 22rd to 46th floor
Co-working: 19th to 21st floor
Technical equipment: 17th/18th floor
Co-working: 15th/16th floor
Hotel: 1st to 14th floor (conferencing: 2nd/3rd floor)
Lobby: ground floor

Rooftop skybar with open air access

Technology and gastronomy of the ONE are housed on the high-rise roof in two attic floors. The official height of ONE is 190.85 meters (626 feet) to the top of the parapet. The building maintenance unit is usually parked below the top edge of the roof. Only during the operating time of the facade access system is moved above the parapet.

Status December 2022: CA Immo has signed two long-term leases for a total of around 3,000 square meters of space. Tenants are the companies Dun & Bradstreet (approx. 2,300 square meters) as well as the law firm and tax consultancy Winheller (approx. 730 square meters).

Status August 2022: Co-working provider Spaces has opened its premises on floors 15 to 21, offering around 6,000 square meters of office space in Tower ONE.


July 2022: The tax consulting firm WTS has signed a lease for 4,900 square meters and will move its headquarters to ONE in the fall of 2023. This means that the pre-lease rate is now 72%. On June 30, formal building inspection also took place. This means that, among other things, the installation of all building services, fire alarm systems and all elevator systems has been carried out in a technically flawless manner. The systems are operational and people’s safety is guaranteed. As a result, the first tenants can move into the high-rise building and nothing stands in the way of regular office operations.

Status May 2022: The occupancy rate is now 60%. CA IMMO indicates a total investment volume of around 431 million euros. Handover to the NH Hotel as the first tenant will take place towards the end of the second quarter of 2022. Furthermore, the building was the first high-rise in Germany and in Central Europe to be awarded the Smartscore certificate of the highest category Platinum by Wiredscore.


Status October 2021: CA Immo has signed a 10-year lease with the Crédit Agricole Corporate and Investment Bank (Crédit Agricole CIB) for around 3,000 square meters (323,000 square feet) of office space on two floors. Crédit Agricole CIB will move its headquarters for Germany to the mixed-use building in March 2023. With the conclusion of this rental agreement, the ONE is already about 59% rented.
