Within one year, the Mohlenhof was built according to the plans of Rudolf Klophaus, August Schoch and Erich Putlitz.
This construction primarily shows the transition from expressionist architecture to the New Objectivity. The concrete skeleton construction has a smooth brick façade with simply cut windows. In front of the main entrance on Burchardplatz, there is a larger-than-life sculpture by Richard Kuöhl. It represents Mercury, who carries a cog on his shoulder and holds a Hammonia in the form of a female figure in his hands, which personifies Hamburg. She is flanked on both sides by 5 reliefs that symbolise the five continents.
