Originally designed with hollow core plank, late in the design stage it was determined that BubbleDeck would allow for considerable cost and time savings. Another consideration was the lack of storage space on the building site which is located in the heart of Rotterdam. The floors were finished in half the time (on average 4 days instead of 8) and the number of floors was increased by 2 to 34 levels while the same overall building elevation was maintained. The building was completed in April 2000.

Throughout this 77,000 ft² building an entirely flush-surface 280 mm BubbleDeck was applied resulting in lower building cost and simplified construction of the flooring system, which contain large open areas for views up into the roof. A shorter building time was achieved, in part because constructing the façades was simplified when using BubbleDeck.
