The facade of the art-depot expresses a rock: sacred, static and solid. The sediments of the rock shown in the facade resemble the historic background of the art.
The tilting glass diamond arouses curiosity from below and makes a balancing contrast with the rock.
The canal and the drawbridge intensify the idea of the valuable content of the art-depot. Once you enter the rock through the bridge, there is a cone-shaped hole getting natural light from above. The spiral staircase leads the visitor through the art-depot; the visitor makes a journey through the history of art. The visitor will be awarded with a panoramic view over Rotterdam when reaching the top. The glass diamond houses the museum and the cafe.
