Rather than intervening in or altering the enclosed spaces of MoMA PS1’s courtyard, Interboro Partners—the winner of the New York competition—highlights the existing space’s seven-sided polygonal shape. A bold canopy of ropes and sails defines the space and provides shade without the visual distraction and spatial interference of a support system at ground level. The focus is on visitors’ interactions with one another and with movable benches, stools, wading pools, and Ping-Pong tables rather than physical encounters with the structure itself. The adjacent side courtyards are treated differently, the smaller one lined with mirrors, the larger filled with a dense urban wood. The intricate canopy, reminiscent of a stringed instrument, casts geometrically complex, shifting shadows on the courtyard’s interior and exterior concrete walls, announcing the project to passersby on the street outside. Interboro has incorporated objects and materials useful to the surrounding community into its design. These elements—furniture and trees—will be donated at the conclusion of the summer.
