There were plenty of reasons why this edition of the Architect 50 was the most competitive yet. For starters, 149 firms submitted entries—the most in recent memory. And the practices that did rise to the top, at least in the business rankings, demonstrated massive revenue gains and enviable growth. First-time entrants made an immediate impression, the most notable of them—WORKac—taking top honors in the design category. In the end, this year was as much about the established heavyweights as the young upstarts: Skidmore, Owings & Merrill became the first to secure the overall Number One position twice.
