Capital C nominated for Rooftop Award 2020

Capital C in Amsterdam - the former Diamond Exchange - has been nominated for the Rooftop Award 2019/2020. Roofs have been nominated for the award that make a sustainable contribution to their environment, are innovative and of course look beautiful.

Rooftop Revolution
The Rooftop Award is an initiative of Rooftop Revolution. Rooftop Revolution brings natural areas back into the city on the largest vacant lot: the roofs. They advise owners on how to get started with making roofs more sustainable, support governments in their climate adaptation ambitions and help 'homeless people' to improve their view.

The award will be presented by the rooftop diva on Friday, September 4, during the Rooftop Symposium on the roof of Capital C in Amsterdam.

Capital C
The building designed by Gerrit van Arkel in 1910 is powerful and idiosyncratic. It is an Amsterdam classic and has of course been declared a national monument. But after several additions, a fire and various renovations, little remains of the original monument. In order to be able to take a step forward and have "face" again, the Diamond Exchange had to largely get its original facade back. The national monument underwent a major renovation to a design by architectural firm ZJA in collaboration with Heyligers design + projects.

On the roof, the two striking towers, the original eaves and the tympanums from Van Arkel's original design have been restored. A special dome made of steel and glass was placed on top of the classical monumental building; the High Light. The construction of the High Light is independent and is a step back from the original façade line and separate from the dome tower. Where the two reconstructed towers are on the roof, the ribs of the steel construction have been left out and a roof terrace has been constructed.
