The Westmoreland Park Pavilion’s formal ingenuity is inspired by a primary form of shading: cloud cover. A welcome sight on a hot sunny day, cloud cover offers a range of diffuse and filtered light that changes throughout the day. Like cloud formations, the pavilion appears striking against the blue sky. Playful shadow patterns are cast across the ground changing throughout the day. Its innovative, freely undulating ceiling is modeled after cirrocumulus undulatus cloud cover common in the region. The suspended louvers conceal the structure from which it is hung. The profiled steel louvers range in depth creating a subtly shifting variation in the density of light filtering through the ceiling. The frequency and blade-like thinness cause the pavilion’s 90 steel louvers to appear to dissolve into one another. The pavilion was designed to be shop fabricated to minimize on-site assembly.
