Greenway Plaza  Greenway Plaza is a business district located along Interstate 69 (U.S. Highway 59) within the Interstate 610 loop in southwestern Houston, Texas, west of Downtown and east of Uptown. The district is located immediately west of Upper Kirby, north of West University Place, and south of River Oaks. First envisioned in the late 1960s by local developer Kenneth L. Schnitzer, Greenway Plaza has evolved into one of Greater Houston's largest employment centers, with over of office space on a campus. Noted for its expansive green spaces and consistent modernist architectural style, Greenway Plaza is widely considered a pioneering example of mixed-use development in the United States. The campus's ten office towers are connected by an extensive system of air-conditioned skyways, tunnels, and underground parking garages. Greenway Plaza contains Lakewood Church, a nondenominational Christian church, which hosts one of the largest congregations in the United States. Lakewood's main campus, a venue originally known as "The Summit" and later "Compaq Center," is the former home of the Houston Rockets, a professional basketball team, as well as other sporting teams, concerts, and events. Lakewood Church purchased the property in 2005. The Greenway Plaza development is part of a larger neighborhood, Greenway/Upper Kirby, which covers a area roughly enclosed by Westheimer Road to the north, Bissonnet Street to the south, Uptown Houston to the west, and Shepherd Drive to the east. In 2015, Greenway/Upper Kirby had an estimated population of 21,120 and a population density of . Kenneth L. Schnitzer, the chairperson of the Century Development Corporation, envisioned Greenway Plaza, which became the first mixed-use development in Houston. Century took realtors from outlying towns around Houston and had them buy individual parcels for very inexpensive prices while trying not to attract attention. One homeowner found out about the plan and asked to have the house sold for $350,000. At the time it was a lot of money for a house that was small. The company paid the money so it could secure the tract the house sat on. The grand opening took place in 1973. Schnitzer said that Greenway Plaza would become a "second downtown". Bill Schadewald of the "Houston Press" said that Greenway Plaza, which housed office towers, retail operations, a basketball arena, a movie theater, and a hotel, "defined the multiuse concept in an original "Edge City"".
