Berlin Underground


583 million people – that’s how many passengers used the Berlin underground, operated by the Berliner Verkehrsbetriebe (BVG), in 2019 alone. Nevertheless, the stations should look well-maintained and stay in good shape for a long time. No easy task for the “Sachgebiet Projektmanagement Bahnhöfe” of the BVG. Architect Martin Renz and his team are responsible for the internal architecture and planning here. 20 architects and engineers take care of the planning for new underground stations and the renovation of existing ones – setting hard requirements for the materials in the interest of the passengers as well as the company. The BVG mainly uses tiles from the Core Collection Solids, Terra, and Quartz: all in dark grey with a light grey contrast. As these colours underline the plain, discrete elegance of the tiles, they are also less susceptible to dirt. In addition, the BVG uses different tile formats. Although most floors are equipped with 60 x 60 centimetres or 60 x 90 centimetres, they also make use of 30 x 60 centimetres. Martin Renz is pleased: “The different formats, which we can play with, give us many options. This is great.” “Our stations have been built in very different times and are characterized by a large architectural variety. Mosa tiles are elegant and plain, but they are also timeless. Thus, they neatly fit into the ambience of each station without pushing their way into the foreground.” Currently, 10 stations are either already equipped with Mosa tiles or in the building phase. For the coming years, many more are in planning. As each project is individually adapted to the requirements of the respective station, the exact compilation of tiles differs every time. “For us, each station has its own history – and thus needs its own solution.
