Park Towers is a complex of two office buildings along the 610 Loop in Houston, Texas, United States. It consists of two 18 story office towers, Park Towers North and Park Towers South, which each have 272621sqft of rentable space, and one six story parking garage. The building, in proximity to Uptown Houston, is owned by Post Oak Partners LLP; TPMC Realty Corp. provides leasing and management services. Previously Cameron International Corporation maintained its international headquarters in Park Towers South.HistoryThe buildings were built in 1972 and 1973. Throughout the complex's history Halliburton, Philadelphia Life, and Tenneco rented space in the complex. By 1992 the buildings were vacant. Lynn Cook of the Houston Business Journal said in 1999 that "for more than a decade Park Towers has sat like a stark white elephant."In December Holliday Fenoglio Fowler secured financing to allow TPMC Realty Corp. to extensively renovate the buildings. TPMC stripped the buildings to their concrete and steel girders and then rebuilt the two towers. TPMC rebuilt the twin towers with glass curtain walls and expanded the floor plates to 22000sqft. 60000sqft of office space was added to the complex. By 2000 PentaSafe Securities Technologies announced that it was leasing 89000sqft in the Park Towers. PentaSafe, the first tenant in the new Park Towers in August 2000, was acquired by NetIQ in 2002.
