For the architect, the main challenge of this development lay in realizing an open, flowing concept of internal space, while establishing strong links with the outdoor realm. Constructionally, this was achieved with a complex, three-dimensional composition, using prestressed flat slabs, point-supported, rough-finished wall slabs – offset to each other – and cantlevered balcony slabs. The structure exploits the scope of prestressed concrete. The terrazzo pavings are continued externally on the balconies. A striking contrast exists between the solid character of the concrete and the dematerialized building skin with its almost continuous areas of glazing, which are not even interrupted by columns.
