A side shot of the impressive and unique Shell-Haus in Berlin, Germany. It was built in 1930-31 and takes its name from the oil company, Royal Dutch Shell. At the time the building was noted for its modernist design, for its striking wave-like facade, and for being one of the first steel-framed high-rise buildings in Berlin. In retrospect it is regarded as Fahrenkamp’s masterpiece and one of the most significant office block designs of the Weimar Republic.
