The Seahawks moved into the 200,000 square foot waterfront facility in August 2008. Virginia Mason Athletic Center (VMAC) is the second-largest facility in the NFL.

The property is bounded by Interstate 405 to the east, Lake Washington to the west, residential property to the north and 44th Street to the south.

The privately funded practice facility is situated on 19 acres of industrial property. It houses a permanent indoor practice facility, and the team's entire front office. In addition, there are three outdoor practice fields, 50,000 square feet of training facility space, 15,000 square feet of player meeting space and 48,000 square feet of administrative office space. VMAC allows fans to watch practice during training camp.

Purchased by Vulcan Real Estate in 2000, the land was formerly home to a coal tar refinery & creosote plant, since remediated by Vulcan in concert with the City of Renton and the Washington State Department of Ecology. The project will improve the environmental climate of Renton and its wetlands by improving and redeveloping the site. Since the team's inaugural season in 1976, the Seahawks were housed at Carillon Point for 10.5 years from 1976-1986.
