The events of the Second World War were unable to slow down the entrepreneurship of Heinrich Hansen. After a fresh start in 1945 and the later relocation of the office to the Ost-West-Strasse there was a further move to the building on Heilholtkamp. Since July 2005 the head office has been located in the newly-developed HafenCity Hamburg, Am Sandtorkai, directly next to the old historic Speicherstadt.
However, Hansen & Rosenthal has always remained true to its hanseatic tradition: on the one hand, to remain grounded and maintain existing relationships and, on the other, to build global contacts and extend business relationships.
