The Arizona Cardinals have started work on their 250,000-square-foot combined training facility and offices for its business operations.

The $200 million facility will be developed on 30 acres of a 217-acre property located west of Scottsdale Road and north of the Loop 101 near the border of Phoenix and Scottsdale. The Cardinals acquired the site last year at auction from the Arizona State Land Department for $136 million.

The new facility will include three natural-grass outdoor practice fields and a fieldhouse with a full-size turf field. There will also be spaces for athletic training, sports medicine, strength and conditioning, as well as dining areas, meeting rooms and a player lounge.

The Phoenix Business Journal reports the office portion of the project will be part of a larger mixed-use development that will include restaurant, retail and residential spaces.

The Cardinals control the rest of the more than 185 acres of the property and are actively marketing it toward headquarters campuses for large businesses.

Construction on the headquarters is expected be completed before the start of the 2028 NFL season.
