New owner of major Dallas North Tollway office project is about to start a redo

The three-building Colonnade office complex contains more than 1 million square feet of business space.

The new owner of one of the biggest office projects on the Dallas North Tollway is about to begin renovations.

New York-based Fortis Property Group bought the three-building Colonnade high-rise project in April.

The more than 1 million-square-foot office complex in Addison was built in the late 1980s and 1990s.
