STG Design, headquartered in Austin, has unveiled designs for O27, a 32-story office tower in Houston's River Oaks area. The skyscraper will have a nine-story base that includes a parking garage, adaptable office spaces, upscale amenities, and a rooftop terrace. Its exterior will feature curving glass facades and triangular glass panels, creating a reflective appearance. The firm characterizes the building as innovative and fluid, resulting from a computational design approach aimed at optimizing floor plates. Broadview Capital, established by brothers Anish and Ashay Bavishi, draws inspiration from Houston's Williams Tower. O27 is intended to represent the city's ambition and elegance, with a projected completion date of 2028. STG Design was founded in 1976.
