Los Angeles has a reputation for unabashed architectural eclecticism, and The Broad Museum, by Diller Scofidio + Renfro (DSR), next-door to Gehry's Disney Hall, is a radical example of such contrasts. While the iconic concert hall is sculpturally exuberant, metallic, and reflective, the museum is boxy, with a deeply perforated cementitious wrapper, almost a honeycomb, lifted at two corners for its entrances.
