The World's 20 Largest Architecture Firms

The World's 20 Largest Architecture Firms

Earlier this year, BDOnline released the 2017 edition of the WA 100, their annual survey of the world's largest practices. Ranking the firms by the number of architects they employ, the full report also investigates these firms' financial records and industry trends. The top spots show only slight changes from last year's rankings, with Japan's Nikken Sekkei taking second place from AECOM being perhaps the most notable change. However, the big story behind this year's WA 100 is the rapid growth of #1 firm Gensler, with the firm increasing their lead from last year. The firm now employs almost 800 more architects than any other firm in the world.

"Gensler’s total domination of the rankings continues as it achieves the seemingly impossible task of growing still more after last year’s huge leap in size," says BDOnline, noting that the company's total of 2,570 employed architects represents an increase of almost 1,000 in under 2 years. Gensler's co-chief executive Diane Hoskins explains this growth as the result of expanding overseas while continuing to expand in the US. "It’s not an either/or," she explained to BDOnline.
