The Diamond Exchange in Amsterdam, now known as Capital C Amsterdam, a design by architectural studio ZJA in collaboration with Heyligers architects, has won an Architecture & Design Collection (ADC) Award 2023. The project won Gold in the ‘Renovation and Restoration’ category. Reborn as Capital C Amsterdam, this former Diamond Exchange in Amsterdam stands as a meaningful and vibrant addition to the city. A new center for the creative industry housed in a sparkling monument that elegantly merges past and present. 

Major renovation of a Dutch monument
When the architects of ZJA and Heyligers first entered the building, they discovered a worn-out environment, concealing the hidden beauty of the historic building behind suspended ceilings and wall facings. The subsequent major renovation aimed to fully restore the original features lost in a fire and due to past adaptations, reviving the vision and beauty of the original 1911 building by Gerrit van Arkel. The architects successfully added a cellar and an iconic, parametrically designed glass dome, breathing new life into this historical monument.
