At the end of the nineteenth century industrialization brought forth large-scale corporations, causing an explosion in the scope of historical city growth. New districts with names such as Borsigwalde, Spindlersfeld or Siemenstadt sprang up around the factories of enterprises as these migrated out to the undeveloped areas outside the city. Located between Charlottenburg and Spandau, Siemensstadt is an example of this development in Berlin. The center of the district is not constituted by church and city hall as is customary, but rather by administrative centers of large cooperations. Larger than the city hall of any Berlin district, such locations for the first time documented the international standing of these corporations. The Siemens architect Karl Janisch set the administrative structure against a cathedral of engineering in the impressive Dynamowerk. The head of the enterprise, its strategic center, was integrated into a unified complex with its technical heart, the large-scale assembly structure for the Dynamo generator invented by Werner von Siemens. The next forty years of company architecture were defined by the architect Hans Hertlein, who created the "Siemens style" with his unique industrial architecture. Among his most important structures in Siemensstadt are the storage building begun in 1916 and expanded in several construction phases until 1928 and the ten-story disk of the control center on Nonnendammallee built from 1926-28; along with the Wernerwerk industrial high-rise on Siemensdamm, erected in two construction phases from 1928-30 and 1936/37 and the prominent five to ten-story, triple-angled buildings of the Wernerwerk XV on Siemensdamm, erected in four construction phases from 1924 to 1941.
>While the red clinker façades of his first high-rise steel-frame construction were still pillar structures accentuated by immense, protruding staircase towers and graduated upper stories, beginning in the 1930's Hertlein designed smooth cubical buildings, offering a moving silhouette of interlocked wing structures of different heights and looming staircase towers.
