One of the world’s foremost basketball players has built one of the world’s largest athlete's mansion complexes. It’s located in the 55-estate luxury community developed by eminent golfer Jack Nicklaus, the Bears Club. The community is already very private, but Jordan’s grounds have a two-story guardhouse. Naturally, the sprawling estate also features an athletic wing with a basketball court and gym, a guest house, and a pool house.
