Delftse Poort Offices
The insurance company Nationale Nederlanden invited 5 Dutch architects to compete and design a preliminary plan: Quist, Kraaijvanger Urbis, Van Mourik and Coenen. Bonnema was chosen unanimous not only because of its efficiency but largely because of its image: strong but slender. Bonnema convinced the board to make an even higher building they first intended to, with more floor area, to enhance the proportions and the architectural impact. It was immediately the largest building in the Netherlands, with 151,35 m. It is used by insurance companies Nationale Nederlanden and RVS Verzekeringen, and the ING Bank. Building this new headquarters high-rise office building was one step further in a long lasting development plan for this area. Enclosed between the railway tracks, station-square and the large Weena street, this spot was studied by many architects and urban designers before Bonnema started.
