6705 & 6707 -Exceptional Development Opportunity – 6 Replatted Lots! Rare opportunity to own six newly replatted lots in one of Houston's rapidly growing areas. Formerly two cleared lots totaling approximately 10,000 square feet, the property has now been replatted into six individual lots, creating outstanding potential for builders, developers, or investors. Surrounded by new construction, this is an ideal location for modern homes or a small residential development. Don't miss the chance to invest in an area experiencing strong growth and ongoing revitalization. Conveniently located just minutes from the Texas Medical Center (~3 miles), Downtown Houston (~5 miles), Hermann Park, the Houston Zoo, Rice University, the University of Houston, Texas Southern University, NRG Stadium, the Museum District, Discovery Green, Daikin Park, Toyota Center, Hobby Airport, and major highways including I-45, I-69, SH 288, and Loop 610.
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.
