A key downtown Dallas development site is up for grabs.

The 18,000-square-foot property on Ross Avenue is part of the mixed-use project under construction across the street from the Trammell Crow Center skyscraper.

The project includes a new parking garage, retail and hotel at Ross and Harwood Street.

Investor JPMorgan Asset Management Stream Realty Partners are building the high-rise project as part of a $135 million redevelopment of the 32-year-old Trammell Crow Center.

Along with what's under construction, there is a proposed high-rise residential site at Ross and Olive Street.

That's what's been listed for sale with Dallas-based Holliday Fenoglio Fowler LP.

"Investors will be purchasing the 18,000-square-foot site on 2000 Ross adjacent to the parking garage," HFF says in marketing materials for the property. "This high profile urban infill location is strategically position in the heart of Dallas on 0.4132 acres with flexible zoning allowing multiple uses and no height or setback restrictions.

The 2000 Ross mixed-use project that's under construction includes a 200-room, $50 million hotel on top of a 10-story parking garage. There's 25,750 square feet of ground floor retail.

The project along with the Trammell Crow Center renovations are scheduled for completion in late 2018.
