As part of the Lincoln Center Redevelopment Project, the Juilliard School needed another of space and wanted Alice Tully Hall's interiors and public spaces to be more welcoming. The expansion by Diller Scofidio + Renfro and FXFOWLE extended the travertine cladding of the original building along the West 65th Street facade, and also created an adapted extension of the Brutalist geometries on the upper stories. The fourth-story row of recesses housing windows is extended, but with the glass displaced and extending beyond the recesses, differentiating the extension from the original building and subtly beginning to break the original Brutalist box. The Juilliard extension cantilevers over a sunken public plaza and a new 38-foot-6-inch-high glazed lobby. The underside of the extension tilts up at a 16-degree angle. A dance studio punches through the curtain wall, overlooking Broadway. The transparency of the entry makes it feel like an extension of the Broadway sidewalk. A grandstand of bleacher-style seating on the far corner of the plaza rises at a similar angle to the canopy.
