Excerpts:
This project, the Delegation of the Ismaili Imamat, is the world’s first building representing the Aga Khan Development Network (which supports social, economic and cultural projects in developing countries). 
Specifically CAF was called upon to create 180 highly intricate panels – that when joined form the aluminum screen that today encloses the 55-foot-high atrium, located just beneath the dome at the Delegation of the Ismaili Imamat. These cast aluminum screens partially obscure the glass walls with their Arabesque-type pattern, a double layer of repeating hexagons. This screen of patterned cast aluminum evokes the screens of carved marble and wood that filter light in historic Islamic architecture.
