In 2009, the data center on the Zuidas in Amsterdam was increased from 106 to almost 150 meters, making it one of the tallest buildings in the city. Moreover, the tower was embellished that year, based on a design by architect Christof Schwencke. The concrete shaft of the tower set in an azure color. The shaft, an area of ​​more than two thousand square meters, is provided with five layers of coating. One of the requirements that the municipality of Amsterdam set for granting the building permit concerned the aesthetic aspect. The tower was not out of place with the prestigious and beautifully designed buildings on the Zuidas.

Light art has been installed in the tower. The design of the light art is an initiative of Project Bureau Zuidas, Virtual Museum Zuidas and KPN. The work, White Noise, comes from the renowned light artist Giny Vos. When it gets dark, a constantly changing image of planets and stars appears on the tower. A twinkling universe where meteorites roam through and small explosions take place. Sometimes codes of letters and numbers appear in this universe as a sign of human communication.
