De Young Museum

San Francisco, CA


KHS&S was responsible for the design-build of the exterior framing system for the one-of-a-kind facades of this landmark building in San Francisco’s Golden Gate Park. Designed by renowned architects Herzog & de Meuron, the three-level, 293,000-square-foot building features facades of wavy copper panels, perforated and textured to replicate the impression made by light filtering through a tree canopy. Copper was selected because of its oxidation properties, which allow the panels to change, over time, from copper to cinnamon to a rich patina, blending beautifully with the heavily wooded environment of Golden Gate Park.
