Designed by the architectural firms AECOM and SHoP Architects in collaboration with The Hunt Construction Group, the exterior of the structure consists of woven bands of weathered steel that wrap around the building. These bands seem to flow into a canopy over the main entrance at the intersection of Atlantic and Flatbush Avenues. Built into the canopy is an open, oval oculus that houses a 3,000-square feet, 360 degree LED marquee. Large areas of glass at street level offer direct views into the arena, which creates a strong visual connection to the surrounding urban neighbourhood.
Inside, it features 9,000 square feet, glass-enclosed GEICO Atrium, which greets visitors as they enter. The atrium offers views of the arena bowl and scoreboard, as well as easy access to the 12-booth American Express Box Office, and views into the below-grade practice court. Designed to accommodate upto 18,000 for basketball and up to 19,000 for concerts, the seating bowl has been included in the design layout of the arena. The arena also features 95 luxury suites, four party suites, and two conference suites, along with four bars/lounges, four clubs, a full-service club/restaurant, and a number of street-accessible retail stores.
Designed to meet LEED certification (Leadership in Energy and Environmental Design) guidelines, the Barclays Centre expects to receive LEED Silver certification. The arena will officially open on 28 September 2012.
