The Sportime/John McEnroe Tennis Academy is the largest public tennis facility built in New York City in half a century. The project is a key component of the redevelopment of Randall's Island into a city wide destination for sports and active recreation. Built on a six acre site, the design includes a 20-court complex with five permanently enclosed and fifteen seasonal indoor/outdoor courts, a 16,000 SF clubhouse, stadium seating for 1,200 spectators which expands to 2,500 during tournament events, and plazas. The large building, clad in metal panels in blue and bright green, contains five courts, clubhouse and stadium. Fifteen courts are covered seasonally with air-supported membrane structures. The design incorporates numerous environmental strategies, including a unique ventilation system for the 5 enclosed courts. Abundant natural light is brought into both ends of the courts in the metal building by the slight rotation of the clubhouse.
