Adolf Hitler had planned already since 1934 an enlargement of the Reich Chancellery. Originally it was planned to only use Voßstraße 2-5, the properties already owned by the German Reich by this time. However By 1936, with the increasingly aggressive foreign policies that Hitler implemented, he also wanted to demonstrate his power with a new big building. So in early 1936 he gave Albert Speer the contract to build him a New Reich Chancellery which should start at the Palais Borsig and stretch then over the whole length of northern Voßstraße. The construction began in 1937 and was completed in 1939.
