The Chilehaus building was designed by the architect Fritz Höger and built between 1922 and 1924. It was commissioned by the shipping magnate Henry B. Sloman, who made his fortune trading saltpeter from Chile, hence the name Chile House. The cost of construction is difficult to determine, as the Chile House was built during the period of hyperinflation that struck Germany during the early 1920s, but is estimated to have been more than 10 million reichsmark. As the first site in Hamburg, it has been awarded the status of UNESCO World Heritage Site on 5 July 2015.
The Hamburg Kontorhaus District is an office district built to serve the functions arising from creation of the Speicherstadt, and forming one of the most impressive German urban settings of the 1920s. It is the first dedicated office district on the continent of Europe. It is characterised by a high degree of stylistic consistency, and was executed in the 1920s, 30s and 50s with virtually no change resulting from the Second World War. Particularly good examples of the style are the Chilehaus, Messberghof and Sprinkenhof, which are among the most significant of all the architectural heritage of that period.
