the platform should appear delicate and should allow for insights and outlooks. hence the platform and the stairs are developped as a steel grid leaving the space underneath only temperated and protected from wind and water.

the construction of the buildings is fairly simple. forces are transfered by regularly placed cross walls. thus the cross walls on the floor above the great hall serve as beams for the long span over the hall. this construction leaves the fassades facing the square free so that they can be moved inwards or outwards building balconies. the balustrade runs along the whole length of the fassade as a structuring element.
