Here's a building I'm sure you will be very familiar with:
The Chile-Haus. A ten-story office building that was
designed by the architect Fritz Höger and built between
1922 and 1924. It is considered to be a masterpiece of
German clinker expressionism. The typical dark-red to
violet fired "clinker" bricks that are characteristic of brick
expressionist style, and connected to the reinforced
concrete core as the load bearing structure.
