FedExForum was designed by architectural firm Ellerbe Becket. Concrete work done with the help of Dowco Construction and Apac. The arena is 805,850 ft² (75,000 m²) in size, covering 14 acres (57,000 m²). The Arena is round, with a dome. The playing floor is lower than ground level. It is capable of seating 18,119 for basketball and has 1,000 premiere courtside seats. There are 27 courtside suites, 32 club suites, 4 party suites, and 80 club boxes. It also contains a full-sized practice basketball court, visible from the huge lobby. The plans called for a mass transit bus depot, which brought a federal grant of $6 million, but the depot was changed to a premium parking garage, and Memphis had to return the money.
