Office on the Quay (Kontor am Kai), Phoenix Lake, Dortmund, 2019

The office and commercial building Kontor am Kai is located in the urban center of the Phoenix Lake in Dortmund. A lake with a water surface of 24 hectares was created on the former Thyssen Krupp industrial estate. Living, working and leisure by the water: a sports harbor with a historic castle forms the urban center of the Phoenix Lake. Here, the main entrance to the lake is created as the junction to the central district of Dortmund-Hörde, a former steel location about 5 km south-east of the city center of Dortmund. The castle square between the harbor, Tull villa, historic castle and Kontor am Kai forms the nucleus of activity on the lake.

With its urban setting, the building blends harmoniously into the existing building structure and sets a strong architectural accent for the future central harbor area. The volumetric comb structure developed for this purpose creates two individual courtyards on the street side for access to the buildings. Three building wings clad in light limestone penetrate the glazed longitudinal wing of the building. Set backs and risalites divide the structure and allude to the architecture of the Hörder castle.
