An Architecture Masterprize winner in the mixed-use category, the Diamond Exchange, Capital C in Amsterdam, originally built in 1911, has been transformed, including the “High Light,” a glass and steel dome that added space for various corporate events and gatherings. The faceted diamond-like form, by ZJA with Heyligers design + projects, is reminiscent of the building's original purpose as a facility for processing the importation of diamonds. Much of the renovation restored the original Gerrit van Arkel design, but also adapted the interior for use as a modern, flexible, office environment. The project has won numerous other design awards.

Octatube's PV Integrated Glass Dome was used.
