one eleven congress was opened in 1987, developed by dallas-based vantage bros. in a joint venture with austin-based carpenter development and the prospect company of dallas. originally, a 15-story, 20,000 square foot hotel tower was to be built on the northwest side of the building, connected via a glass atrium. the building would have stepped down towards congress avenue creating stairs to the first setback on one eleven congress; this project was put on hold and eventually canceled.
