Demolition and rebuilding of a 9-storey office complex with 3 basements and a penthouse level.

The facade is a perforated curtain wall.

The upper level is set back from the other levels.

The penthouse thus frees up accessible roof terraces as well as space for open-air plant units.

The office areas on the last level are covered by a metal frame structure.

The horizontal stability of the building is ensured by the slabs transmitting wind forces to the windbracing cores.
