The entrance to the Winspear Opera House features the Annette and Harold Simmons Signature Glass Facade, which ascends 60 feet creating a seamless visual appearance between the vibrant red glass panels of the McDermott Performance Hall and the surrounding Sammons Park. Radiating from the Winspear Opera House on all sides, the Sky Canopy provides shade to the Simmons Glass Facade over three acres of Sammons Park, defining new outdoor spaces for visitors to gather.

The principal performance space, The Margaret McDermott Performance Hall, features retractable screens, a spacious fly-tower, a three-square stage with generous side and rear stage areas, variable acoustics, and accommodates 2,200 patrons.
