With the new Bürgerpark and the
civic center, a contemporary cultural setting has been created for Reutlingen
at the entrance to the medieval city. Following the main objectives of carving
out visual axes, marking pathways, and preserving natural space, the new
lighting strengthens the functions and evening atmosphere of this important
urban space.

The historically listed building ensemble consisting of the opera house, theater, and opera terraces, built between 1954 and 1962 according to designs by the architect Wilhelm Riphahn, is slated for general renovation. The project is still in the planning stage. Completion (including the new children`s opera): 2015

St. Martin's Church in Kassel is the seat of the Bishop of Kurhessen-Waldeck. The church is frequently used for events and thus requires highly flexible options for lighting the interior of the church. At the same time, the simple lighting from the 1950s, which had come to be well loved, was to be retained at the congregation's request.
The solution combined the old glass pendant luminaires with new, freely adjustable LED spotlights on the cross vaults to illuminate the stage and alter room, the organ and special works of art.

On the foundations of the old Petri Church in Berlin, a new sacred building is being built that will unite the three monotheistic world religions of Judaism, Christianity and Islam under one roof. It will be a house of encounter, for people of different religions to get to know each other and exchange ideas. Three sacred rooms are arranged around a central domed room. Above this, the building opens up to the city with a loggia and offers views over Berlin.

For the imposing dome room in the centre of the building, we developed a discreet wall luminaire with several lighting components. This allows us to illuminate the entire room as well as the dome in a balanced way with just a few luminaires. A universal luminaire in the same aesthetics, also developed by us, provides uniform illumination of the circulation areas throughout the building. In the sacred rooms, skylights optimised by us with different characteristics create an appropriate room atmosphere with daylight. At night, this is taken over by the precisely planned room lighting consisting of simple pendant and surface-mounted luminaires.

The old fortress structure is a modern center for culture and administration with the museum for medieval church and cultural history in Brandenburg, the chapel, the Bergfried tower, the local historical museum, the tourist information, the library, and the Ziesar government office.
