Morgan Stanley is weighing a $1.3 billion office tower in Dallas, the latest Wall Street giant to bet on Texas as a financial hub.

The New York-based bank would consolidate several businesses that have been growing in different parts of the city into a 709,000-square-foot skyscraper at 2401 McKinney Avenue, according to city documents. The property, less than a mile from the $500 million campus rival Goldman Sachs Group Inc. is building, is owned by Trammell Crow Co. and currently houses a seafood restaurant and a defunct gym.
