It is an office building in Hamburg that the shipping company Robert Miles Sloman had built from 1908 to 1910 according to plans by the architect Martin Haller. In 1921 it was expanded and changed according to plans by Fritz Höger. At the time, it was the largest office complex on the edge of the harbor.
The Slomanhaus was renovated by 2003 and is now used as an office complex with 11,000 square meters of office space. The paternoster from 1921 in the Steinhöft stairwell is - alongside those in the GIGA German Institute of Global and Area Studies, in the Eimsbüttel district office in the Grindel tower and in the House of the Patriotic Society - one of the few historical elevators in Hamburg that are still in operation. It is the oldest functioning elevator of its kind in the world.
The Slomanhaus is one of a number of office buildings in the area and has entrances at Baumall and Steinhöft. It is opposite the Kehrwiederspitze of the Speicherstadt.

In 2000 the Slomanhaus was placed under monument protection.
