The Diamond Exchange, Capital C Amsterdam has been awarded the National Steel Prize 2020. The national monument underwent a major renovation to a design by Heyligers design + projects in collaboration with architectural firm ZJA and has been restored to its former glory. The High Light, a special, naturally formed dome of steel and glass, shines on the roof. Distinctive is the way in which the High Light is both an eye-catcher and a self-aware sign, yet made so light that it acts to serve the historical monument.

Jury member Wico Ankersmit: “The majority of the restoration to Gerrit van Arkel’s original design may be considered a success. After the building was given a modern roof structure in 1990, it has now been carefully restored to its original form and a contemporary volume has been added. The transparent and spherical new roof structure with organic lines is clearly present on the roof, but it is not. It leaves the original shape completely intact, is not obtrusive, but also offers an exciting, contemporary addition. Constructively it is a spectacular design, in which little extra steel has been used and is nicely fitted without appearing pompous. Here we see an innovative construction with sophisticated detailing. A combination of techniques in design and implementation, and that at an inner city location. Modern on classic. It makes sense.”
