Architect-engineer HOK, a firm of 1,600 people in 23 offices, announced today the pending acquisition of 360 Architecture, a 10-year-old firm of nearly 200 people with a sports venue specialty, formed by the merger of Heinlein Schrock Stearns and CDFM.

The move will bring sports design back to HOK, which, until 5.5 years ago formerly owned sports architect veteran HOK Sport + Enterntainment, now Populous. 360 will give up its name in the deal, which is expected to be finalized by the end of October.

360 is perhaps best known for its edgy design for a new stadium for the Atlanta Falcons, just getting under way. The design includes a kinetic roof that opens much like a camera aperture but without rotation.

360 Architecture works is participating on design teams for the renovation of Sun Life Stadium for the NFL’s Miami Dolphins; the Rogers Place arena for the National Hockey League’s Edmonton Oilers in Edmonton, Alberta; the AT&T Center renovation for the National Basketball Association’s San Antonio Spurs in San Antonio, Texas; the design of Cisco Field, a proposed new ballpark for Major League Baseball’s Oakland Athletics in San Jose, Calif.; and a new stadium for the Major League Soccer’s San Jose Earthquakes.

In the higher education sector, 360 Architecture is playing a role in the design of Notre Dame University’s Campus Crossroads project in South Bend, Ind., and the Beauchamp Recreation & Wellness Center at the University of Portland. The firm recently completed the design of recreation and wellness centers at Auburn University’s main campus in Auburn and at its campus in Montgomery, Ala. In addition, 360 Architecture is involved in creating athletic facility master plans for the University of Missouri and the University of North Carolina.

Stay tuned for more details about the deal in ENR.
