A nonprofit will open a museum and event center at the site.

Mercury One, a Texas-based nonprofit, has signed a 172,089-square-foot lease at 6655 MacArthur Blvd. in Irving, Texas, occupying the full building. Orion Properties owns the property, which is part of the larger Las Colinas master-planned development. Cushman & Wakefield represented the owner.

This lease is the largest new office lease in Las Colinas since 2021, according to Cushman & Wakefield, and the asset was vacant prior to the lease agreement. Mercury One and The American Journey Experience plan to use the space for a history museum and event center, Steven Palmesi, manager of investments at Orion Properties, said in prepared remarks.

Orion purchased the three-story asset in 2010 from iStar for $22.3 million, or $129.19 per square foot, according to Yardi Matrix. 6655 MacArthur Blvd. came online in 1997 with Champion Partners as the owner.

The larger development spans 12,000 acres and was originally founded in 1973 by Ben Carpender. Las Colinas features a mix of residential, commercial, retail and educational assets. Last May, DFW LAND purchased Corporate Point, a 242,000-square-foot 10-story located in the development. The Irving Convention Center anchors the Urban Center, the business district of the campus.

Multiple DART stations can be found across the campus and the MacArthur at Fluor bus stop is outside the office building. Dallas-Fort Worth International Airport is less than 7 miles away from the property.

Cushman & Wakefield Vice Chairman Matt Schendle and Senior Associate Mary Frances Burnette represented Orion Properties in the transaction. Mercury One was represented by Senior Director Steve Wentz.

Following the acquisition, the property was rebranded to One Provident Place.

Last month, Balfour Beauty signed a 35,139-square-foot lease at One Victory Park. Cushman & Wakefield’s Schendle represented the owner, Clarion Partners, in that transaction as well.
