Rare residential infill opportunity consisting of 12 shovel-ready lots located in the OST–South Union area of Houston. The site is fully platted with utilities available, including City of Houston water and sewer. Lots may be purchased individually or as a 6-lot or 12-lot package, offering flexibility for builders and investors. Ideal for new residential construction with proximity to the Texas Medical Center, Downtown Houston, and major freeway access.
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.
