ONE has been designed as New Work building, combining not only different types of use, but also offering all the possibilities of networked working and communication, with numerous informal meeting places and working locations. A spacious lobby shared by office users and the hotel occupies the entire ground floor and is the urbane centre of the building. In addition to the office reception and hotel check-in area, there are attractive public relaxation areas like lounges and a café. The hotel itself is a four-star superior hotel of the lifestyle brand nhow of the NH Hotel Group with 375 rooms, its own conference area, restaurant, fitness and spa, which has not been seen before in Frankfurt.

On the upper floors of ONE modern office space are currently being moved in to, with structures focused on the New Work era. Flexible office spaces and shared spaces can be adapted to the needs of tenants. ONE also offers all possibilities of smart, modern and technical infrastructure in the digital age. Several floors house a separate area for conference and co-working spaces. These can be rented by users of ONE on flexible and temporary terms. Mobility on site is ensured through additional services such as car & bicycle sharing, coupled with ample parking spaces and areas for securing high-quality bicycles.

The ONE is regarded as a best-in-class office building in terms of architecture, technology and sus-tainability. Accordingly, it has already been awarded triple platinum certification and a Diamond award: For its sustainability, the ONE has received the platinum certificate from the German Sustain-able Building Council (DGNB) and the diamond award also from the DGNB for its outstanding ar-chitecture and urban integration. Furthermore, the building was the first high-rise in Central Europe to be awarded the SmartScore certificate and the WiredScore certificate, both in platinum. ONE was also nominated as one of 34 high-rise buildings worldwide (only 4 of which are in Europe) for the International Highrise Award 2022/23.
