The Delftse Poort consists of a substructure, two tall towers (151 metres and 93 metres high) and a cubic block in between. The substructure runs sixteen metres tall and connects the other buildings to each other. In total, the building houses 60.000m2 of offices and 15.000m2 for other facilities. It has been built on a 100 x 100m2 terrain. The area is crossed by a rapid transit line. The two towers stand on both ends of a metro tunnel, with a multifunctional building in between them. The parking garage can store up to 1.200 parked cars. Aronsohn’s greatest challenge concerned not the height, but the foundational challenges that occurred due to the complex location. The construction pit’s design called for particular attention, and a new foundation had to be realised for the metro. Furthermore, settlement prognoses had to be taken into account
