The employees of the Rhein-Main-Verkehrsverbund (RMV) are currently working in two buildings on the Alte Bleiche, but soon they are all due to move into a new building on the neighbouring property.

The six-storey L-shaped new building with five full floors and a staggered attic is being built on a conversion area in the immediate vicinity of the already existing administration from the 1990s.

At the corner of the building is the central entrance for RMV employees and customers, staged with large illuminated walls. The entrance is connected to the reception with information counters and the post office. A variable switchable conference area develops into the depth of the property. On the upper floors, each divided into 400 square metre units, are the office spaces that can be flexibly divided and played with different usage scenarios.
170 workplaces at the headquarters had to be completely redesigned. In the context of employee workshops, the Fraunhofer Institute has determined the need for, as well as the extent of, additional work opportunities. Based on this survey, MIA Merz Innen. Architektur designed the cross-functional working concept in close collaboration with future users. In addition to the full-fledged workstations in open spaces and still working rooms, there are various other workplaces for concentrated or collaborative work in the area.

The clear design concept of the RMV, which is based, among other things, on a rail network, is integrated into the interior design both in terms of colour and design.
