Lone Star College–Tomball (formerly Tomball College) is one of five colleges in the Lone Star College System (LSCS). Dedicated and opened in 1988, the college sits on a 143 acres (0.58 km) (.5787 km²) on SH 249 north of FM 2920 and just south of Spring Creek, which acts as the border between Harris County and Montgomery County. The mailing address for the campus is 30555 Tomball Highway, Tomball, TX, 77375. In 1985, LSCS purchased 143 acres (0.58 km) in northwest Tomball, Texas. A single megastructure was chosen as the design instead of building several different buildings. The basic design is a cruciform design with each of the four wings named after the compass direction that they point in, this results in a North, South, East and West wing. Since then the college has grown in size. First the South Wing was expanded, several years later, the college went through a major expansion. In this expansion, the West wing was extended; however, the major work occurred in the East Wing, which greatly extended the size of the campus. In 2005 another expansion project was finished, during which time the Library was moved and expanded to its current form as a joint project with Harris County.
