The Drentepark lies at the edge of the Amsterdam Zuidas and next to the city’s ring road. A host of construction projects is to be realised in this area in the years to come, the first one being this 100 metre tall, 30.000m2 office building for Ernst & Young and a 7.000m2 parking garage. The building’s bottom storeys house general facilities for the office, such as reception and communal spaces, conference halls, a restaurant etc. A 50 x 120 m2 underground parking storey stretches the entire office area. A second parking level is constructed on the south side, next to the high-rise construction. The underground structure is designed to minimize drainage complications. The high-rise construction consists of three neighbouring building masses, of which two office buildings with a depth of 14,4 metres and 12,6 metres, and an enclosed core building in between which provides access to the offices. The buildings have shifted 7,2 metres relative to each other. The support structure is made out of V-shaped columns rather than vertical columns, creating a diagrid. These structures not only bear vertical loads, but also a substantial portion of wind loads.
