The Dortmund Theatre was continuously used as an opera house, theatre and playhouse during the conversion of the existing building and the approx. 800 m² new building. The workshops and functional areas were relocated internally to other spaces and outsourced externally as needed.
The House of World Cultures in Berlin is being comprehensively modernised and refurbished by us. Built in 1957 as a congress hall and affectionately called the "pregnant oyster" by Berliners, the building was rededicated as the House of World Cultures in 1989 after partial collapse, reconstruction and vacancy in order to promote dialogue between the continents.
The "Haus der Berliner Festspiele", which was built in the early 1960s and is now a listed building, was extensively renovated, modernised and made fit for modern theatre operations from 2009 to 2011.
After the fall of the Wall, a new location became necessary for the first all-German cultural project: The historic Zeughaus in Berlin's Mitte district was decided upon as the home of the permanent exhibition, and a new building for temporary exhibitions on an adjacent plot of land was soon decided upon. In 1996, I. M. Pei was commissioned with the planning of this extension.
We were commissioned by the collector couple Peter and Irene Ludwig as general planners to renovate and refurbish the Ludwig Galerie in the classicist Schloss Oberhausen. Since its redesign in 1998, the gallery has been one of the internationally renowned exhibition venues in the Ruhr region.
The Chocolate Museum vividly shows the entire process from the growth of the cocoa bean to the finished chocolate product. By converting and extending the former customs yard, an exceptionally successful museum with 600,000 visitors a year was created at the prominently located entrée of Cologne's Rheinauhafen harbour.
