A legacy downtown Dallas skyscraper has hit the market for the first time in more than two decades.

The 40-story Bryan Tower has been owned by Dallas-based Spire Realty Group since the late 1990s.

Now the owners have hired commercial property firm JLL to find a new buyer for the office tower.

Located at Bryan and Harwood streets, the 1.1 million-square-foot office tower built in 1972 was one of the first downtown Dallas projects by legendary developer Trammell Crow. It was the first Dallas financial district high-rise with a reflective glass exterior.

The building has had more than $40 million in upgrades since the early 2000s.

Bryan Tower is 60% leased, but its largest tenant, Baylor Scott & White, is moving out this year

The sale includes three adjoining downtown parking lots plus part ownership in a parking garage.

“Bryan Tower presents prospective investors with the opportunity to convert available office space into residential and/or hospitality space,” JLL says in its pitch for the property. “Current ownership has engaged WDG Architecture to provide renderings and plans to convert existing surface parking into additional commercial space and parking while redesigning an entrance that would be dedicated to the residential or hospitality portion of the tower. “

Along with Baylor Scott & White, other tenants in the office building include Chubb Insurance, Builders First Source and BNY Mellon.
