Office Building, Rudolfplatz
Cologne, Germany 2015–2022
Client: Momeni SEG Competition, first prize
This commission was won in an invited competition organised by the city of Cologne. The new office building for the Hamburg-based developer Momeni SEG will provide 13,000 square metres of offices and retail over eight floors. The site is a major part of a master plan to redevelop a whole city block at Rudolfplatz, an important square around the Hahnentorburg on the west side of central Cologne.
The new building stands next to the historic monument of the Hahnentorburg, which has symbolic significance as a former gate to the mediaeval city. The form of the new building has been designed to complement and sustain the setting of this important place. Its stepped profile and tall face towards the east stands next to the gate and looks directly towards the city centre. The façades are made with masonry piers of a light grey brick that will complement the colour of the limestone walls of the city gate monument.
