Outline Concept
“The area around the ECB is seen as the "sub-centre of the financial world" with its own, independent appreciation in the cityscape of Frankfurt (a city in a city).

The ECB building complex has its precise place in Frankfurt's skyline, as a landmark along the Main.

The composition arises through a correspondence of the individual elements in terms of content, form and significance:

The Grossmarkthalle as a partly ‚open market place‘ in the centre is the meeting point between the ECB and the public, the structure platform acts as ‚serving element‘ and distributor, the high rise buildings as ‚workplace‘ in a rather reserved area.

Each of the three parts of the building (Grossmarkhalle, infrastructure platform, high rise buildings) has a clear, geometric force in its formal structure. It can be clearly seen that the Grossmarkthalle remains at the centre of the new ‚complete building‘ so that it can be seen from all sides.

The rooftop landscape: Clearly structured in stripes with 3 to 4 elements: utilization fields (for sports and games), action fields, green roof surfaces and green recreation-areas (for rest and leisure time).

The inner courtyards: Different topics in the courtyards, with free forms. Two different types of courtyards:

• Shady, quiet courtyards, with grove-like treetops, interplay between shadow and light
  
• Sunny inner courtyards with basins and disk-like shadowing elements.“
