Urban triangle – the new headquarter for a railway company

The realization competition for the new construction of an office building for the railway company “Deutsche Bahn” concerns the revaluation of the area between the main train station, the bus terminal and the shopping street “Lister Meile”.

For the 15 business units the company plans to create 855 new jobs. For the new building, the internal concept of a “Flex-House” had to be incorporated into the architecture of the site and the urban surrounding in order to achieve a consistent urban image.

Therefore, we combined tradition and mobility. The design translates the mission statement of the company into an urban element with a respective identity, thus giving it solidarity and dynamics at the same time.

By designing six floors for the new office building, it takes on the classical and simple lines of the city. Within this composition the accents of the façades find an answer to the counterpart in the urban surrounding.

The ground floors as well as the first floor form the base of the construction; the upper floors slightly protrude, create spatial edges and an accent at the building corners.

The concept of the interior follows the set requirements: A light and friendly communication zone framed by green accents welcomes employees and guests. Green “yards” each of different character provide space for events, seminars and the gastronomy, creating intimacy and concentration for the respective use. A dynamic path network reliably leads into the upper floors. The warm roofs are extensively greened.

Flexible spatial structures and quality awareness when choosing the materials guarantee the durability of the building. Functionality and aging quality set the premises for the economical and ecological handling of existing resources.

In front of the main entrance a public square is created leading into the adjoining areas: the train station, bus terminal, Lister Meile, tram stop, shops, pedestrian zone and city center.

The materials were chosen upon the aspects of sustainability, durability and reusability. The interior design is supported by a differentiated light and color concept. The current energy standard (EnEV 2016) is achieved.
