Vivaldi Tower


The headquarters building for Ernst & Young is located at the gateway to the Vivaldi-park area of the new 
Zuidas district, south of Amsterdam. Commissioned by ING, the tower establishes a landmark on the route 
into the city with its diagrid façade.  The 24-storey building is divided into two twelve metre-wide column 
free towers with open, flexible floor plates. The blocks are staggered in plan to admit as much natural light 
as possible and to make the most of the northerly city views. The northern façade is fully glazed, while 
partial thirty per cent glazing to the east, west and south limits solar gain. Combined with ground water 
storage to further save on energy for cooling, the overall environmental strategy is highly efficient.
Linked by a shared transparent core, the offices are serviced by double-height meeting spaces and lightfilled social spaces allowing communication between different floors. The structural steel diagrid is clad in 
silver aluminium and is offset by opaque black panels, which reduce the definition of the individual floor 
levels.  This lattice scales the entire 87-metre high facade and gives the building its identity. At the base of 
the building the height of the diagrid creates a triple-storey lobby space, while at the top of each 
tower north and south-facing terraces are set into the structure. 
Ten per cent more efficient than the target Dutch environmental standards, the towers are approached via 
a water-court with an ecological pond beneath an overhanging canopy. Defining the relationship between 
public and private, this space houses the social functions, such as staff restaurant, terrace, auditorium and 
bar, clustered around the water-court. Coupled with a green roof on the restaurant building, the pond has 
an important environmental contribution. 65 per cent of rainwater is retained on site while the run-off feeds 
into the Amsterdam canal system to control water levels following peak rainfall. The pond is naturally 
cleansed by a planted biotope of reeds, water lilies and grasses.
