The winner, who was determined on September 17, 1993, was the Berlin architect Hans Kollhoff. Kollhoff's plan was based on Behrens’ design, provided a horseshoe-shaped area of seven- to eight-storey buildings and 150-meter-high towers with 42 floors. The Alexanderhaus and the Berolinahaus – both listed buildings – would form the southwestern boundary. Second place went to the design by Daniel Libeskind and Bernd Faskel. The proposal of the architecture firm Kny & Weber, which was strongly based on the horseshoe shape of Wagner, finally won the third place. The design by Kollhoff was chosen on 7 June 1994 by the Berlin Senate as a basis for the further transformation of Alexanderplatz.
