The concept consists of a core program of parking and offices, business facilities, public space and public facilities, organized within a single main volume. The bottom layers make space for most of the parking functions, and (emergency) water storage facilities. Topping that off is an elevated lush landscape ecosystem, that facilitates achieving the sustainability goals, and the metabolism of the structure. The landscape ecosystem is contained in a transparent enclosure, to deal with Schiphol's restrictions on bird life, health and safety measures, and to allow some control over the elements.
Strewn within the park are multiple office module pavilions. These are built on stilts that keep the landscape open. They are flexible enough to allow for cyclical renovation and relocation, and permit a wide range of designs to allow for individual company expression.
The entire structure works as a circular catalyst within the CBD. It goes beyond the usual solar panels and grey water systems, and aims to close multiple resource flow loops within the area. This means that the concept steps away from importing resources and using them once, but optimizes its systems to create as little waste as possible in water, energy, air pollution, goods, and food. Where possible, it even taps into waste flows from the neighboring buildings in the CBD, making it a truly catalytic building.
