One Allen Center

Houston, Texas

One Allen Center is a 34-story, class “A” office building in the master planned, 3-building Allen Center campus. One Allen Center is located at 500 Dallas Street in downtown Houston.

Allen Center, the iconic 3.16 million square-foot complex has always been synonymous with amenities, service, access and opportunity. Now, more than ever, Houston's premier business address will offer so much more.

The reimagining of Allen Center began in 2016 with the renovation of One Allen Center, which included a transformation of the lobby with a modern two-story glass facade; a re-clad, transparent sky bridge that connects One and Two Allen Center; and a complete re-envisioning of the exterior landscaping with a one-acre greenspace, named The ACRE. Phase II was completed in January 2021, and includes complete lobby renovations for Two and Three Allen Center, new amenities and retail as well as the transformation of the C. Baldwin Hotel.
