One Dallas Center is a modernist skyscraper located in the City Center District of downtown Dallas, Texas, completed in 1979. The building has 30 floors and rises 448 feet. One Dallas Center is currently tied with the Sheraton Dallas Hotel North Tower as the 25th-tallest building in the city. The building was originally planned as part of a three-building complex designed by I.M. Pei & Partners, but only one tower was constructed.
One Dallas Center is now owned by Todd Interests and houses the headquarters of HKS Inc., Greyhound, and Apex Clearing Corporation. The first 15 floors of the high rise are renovated office space, while the top 15 floors are luxury apartment homes constructed and delivered in October 2014. One Dallas Center is professionally managed by Lincoln Property Company.
