Heyligers design + projects has worked in collaboration with architectual firm ZJA on the renovation and the return of the original facade finish. The agencies also jointly developed the design of the futuristic roof structure.
The largest addition to the Diamond Exchange renovation consists of the event space and the terrace on the seventh floor, under an elongated dome. The structure on the roof is based on the principle of the Gridshell, in which the structural forces are absorbed by the double curvatures in the roof surface. This offers enormous freedom of design and enables large spans without columns. Filled with glass, this creates a light-looking, transparent roof structure. By raising the floor of the sixth floor, the dome can look even freer and lighter. The structure is independent and is a step back from the original façade line and separate from the dome tower. The relationship is obvious from the street: the restored Diamond Exchange is paramount and the structure is a serving addition. The new public space is a transparent inviting gesture, reflecting light and the sky in all directions.
With this renovation, the Diamond Exchange has been brought back to the original design by Van Arkel. The new structure echoes the dome of the bell tower, but also evokes the history of the building with its multifaceted brilliance. The dome tower remains the eye-catcher from afar.
Traditionally, a stock exchange has been the meeting place for markets and people, goods and ideas, and that’s how the renewed Diamond Exchange meets the city.
The new owners saw a role for the Diamond Exchange in what can be seen as a new heyday of Amsterdam, now as an international center of the creative industry and information technology, called Capital C.
Capital C offers a contemporary working environment in a unique monument, as well as one of the most spectacular views of the city from a roof with a stylish and iconic structure.
The Diamond Exchange can once again be a full part of the city, as a center for the creative industry, as a public space with a restaurant and space for art. And as a sparkling monumental building that depicts Amsterdam’s past and present.
