The competition invited architects throughout the world to rethink and give an architectural form to their relationship with the city of Athens through the design of ephemeral structures. The structures have specific programmes and themes that can generate cultural events: City-leisure activity generators for individuals or groups. No specific site is given for the installation of the structures. Their design should guarantee easy mounting and de-mounting. All structures should be movable and designed "in the name of Athens". This implies that they should neither be conceived as site-specific nor generic. The ephemeral structures will rather operate as "urban parasites" to be adapted to the existing infrastructure of the sites that host them, and they are expected to invite citizens and visitors to participate in the cultural events they will generate.
Our project proposes a climatic and phenomenological interface. Like water lilies on surface of a pond or parasols on a beach, inflatable elements come to populate public spaces. Their presence will signal the city events of the Olympics. This gathering of scenery will effectively place the patrons of the event "on stage". Located at a constant height, the balloons form a more or less dense surface multiplying themselves organically for intense moments. Whereas during the day they passively provide climate relief by creating a shaded atmosphere, at night they become reactive as their relative luminescence indicates human presence.
The organization of these indicators would take all its sense from the Parthenon, emerging from urban fabric. The sites of activity will be also clearly visible from an aerial approach, providing an interface between the individual and the whole city.
