The Green Oasis @ Alexanderplatz
Using the existing green roof from the Alexanderhaus - Berliner Sparkasse Headquarter = green oasis


For the research I saw for the very first time that the roof deck from the famous Alexanderhaus (Architect: Peter Behrens) and at the same time the headquarter of the Berliner Sparkasse, has already a green roof.

My question was immediately: Is it not possible to use this fantastic place partly for the public?

What might be the use?

  1. Recreation area
  2. Cafe
  3. Exhibition = for example the result from this certain contest could be displayed on the roof deck.
  4. As we can imagine : many things more


It's an eight floor building, the panorama view has to be fantastic. Having in mind: Approx 100.000 People crossing this center square of Berlin each day.

The necessary staircase (translucent glass wall) could be the entrance. It's facing nicely to the Alexanderplatz. It could be partly also used for surprising subtle light installations (having in mind that the building is under monument protection)  and/or could be already an indoor exhibition space in somehow.
