Shadow Pavilion; Ann Arbor, Michigan

PLY Architecture

It was Robert Le Ricolais, early pioneer of surface and space frame structures, that said “the art of structure is where to put the holes”. His eloquent statement is even more relevant today given the ability to link the precision of the computer with the precision of computer controlled cutting equipment.

The Shadow Pavilion explores the paradox of a perforated structure where the removal of material makes a structure lighter and weaker. The Shadow Pavilion, is both a structure and a space made entirely of holes. The pavilion surface is made with over 100 aluminum laser cut cones that vary in size. Beyond testing the limits of sheet aluminum, the cones funnel light and sound to the interior space, offering visitors a space to take in the views and sounds of the surrounding landscape.

Organizational schemes for the cones are explored, including the logic behind the concept of phyllotaxis. In botany, phyllotaxis describes a plant’s spiral packing arrangement of its elements. The organization of the cones may limit the form, but can strengthen the structure. The laser cutting process uses the digital design information to precision cut and finish the aluminum cones.
