Listed by Wykila Green• Keller Williams Realty Southwest
Greater Ost-South Union, located between OST and South Union, is a residential and institutional Houston neighborhood with mid-century brick homes and broad, tree-lined streets. The neighborhood’s character concentrates around the University of Houston campus edge near Calhoun Rd and Wheeler Ave, where student-foot-traffic, coffee counters, and campus venues set the daily rhythm. Architectural lines lean ranch-style and postwar infill, with deep setbacks and long driveways. University of Houston’s Cullen Performance Hall and the Blaffer Art Museum act as cultural anchors, while TDECU Stadium brings game-day energy. Green breaks appear at nearby MacGregor Park, and METRORail access at Palm Center Transit Center links the area to Downtown.
