With the new decade, QT increasingly moved away from office landscape in favour of mixed office forms such as the concept of the reversible office. Projects from this time included the Daimler Benz works in Bremen, DAK head office in Hamburg, and banks Bremer Landesbank and Kreissparkasse Ravensburg.

 

Between 1986 and 1996, the office took over on behalf of NDR (North German Broadcasting Corporation) projects such as the new building for its production and broadcasting centre, the new building for the state broadcasting centre in Mecklenburg-Western Pomerania and the radio annex for the state broadcasting centre in Kiel.
