We transformed an Amsterdam business landmark into an engaging and dynamic multifunctional centrepiece for the newly revived ‘Zuidas’ district. To the original central core with three towers, we added two new towers, embracing the old building. All five towers are connected via a first-floor ‘heart’, from which spaces open out in all directions. We created two more atria, to smoothly bridge the gap between existing and new and to benefit from optimal daylight. The new façade achieves unique transparency in subtly flowing lines, integrating the building beautifully into the public context.
