Junior-Haus

Junior-Haus is a nine-story building at Kaiserplatz featuring a height of about 35 meters and a distinctive round, glass-enclosed staircase at its center. On either side of this staircase extend symmetrical office wings that demonstrate the typical office building layout of the post-war period.

The structure was built in 1951 following the destruction of a previous cafe in 1944, designed by architect Wilhelm Berentzen for Kurt Junior's property company. Its construction was part of Frankfurt's broader post-war rebuilding efforts that reshaped the city.

The building shows how Frankfurt rebuilt itself after the war and reflects the architectural thinking of the 1950s. Its clean lines and functional design represent the modernist approach that shaped the city's recovery during that era.

The building sits between Kaiserstrasse and Friedensstrasse, directly across from the Frankfurter Hof hotel, making it easy to locate. The glass staircase at its center is visible from the street and offers a clear view of the building's structure.

A large Mercedes star remains mounted on the roof, marking the building's long association with the car manufacturer, as it once housed a Mercedes-Benz showroom in its basement for many years. This star has become a quiet landmark visible from various parts of the city.
