Greater Greenspoint, also referred to as the North Houston District, is a 7 sqmi business district and a suburban neighborhood in northern Harris County, Texas, United States, located mostly within the city limits of Houston. Centered around the junction of Interstate 45 and Texas State Highway Beltway 8 near George Bush Intercontinental Airport, the area is a classic example of a planned edge city. The initial 2000 acre retail and office development centered around Greenspoint Mall was a project of the Friendswood Development Company during the 1970s and early 1980s.
