Amsterdam - 2019 will see ING moving from the Amsterdamse Poort area to the company’s new headquarters. Following this move, the G&S Vastgoed, OVG Real Estate and VolkerWessels consortium will transform the office building into a multifunctional program of mainly apartments. With a gross floor area of approximately 91,000 m2, the office is one of the largest commercial buildings in Amsterdam. G&S Vastgoed has requested that the Arcadis landscape architecture & urban development department provide support in the redesign of the unique rooftop gardens, the atria and the public greenery at the complex.
The building comprises a series of towers organized in an S-shape, a layout which creates two spaces within the structure of the building, which has been designed as gardens. In order to create sustainable gardens in an unnatural urban environment, we called on the know-how provided by nature. The conditions encountered in high mountain areas formed the inspiration for a successful rooftop garden construction. The principle was that a balanced ecological system requires the presence of both long and short cycles; slowlygrowing trees and shrubs alternated with seasonal perennials and self-propagating annuals. The designs feature a wide variety of planting styles – from a vegetative decorative English country garden to the sparse grasslands of a flowering meadow.
