While the rankings shuffled this year for many of the Top 25 firms in Architectural Record’s annual list, the No. 1 firm held fast to its position at the top. With nearly $1.2 billion in total revenue in 2017—more than twice that of any other company on the list—Gensler clinched the top spot for the seventh year running. Despite reporting a slight dip in revenues from the previous year, Perkins+Will moved into second place, bumping AECOM, whose revenues also fell, to third.

The annual list, compiled by record’s sister publication Engineering News-Record (ENR), ranks companies by their architectural revenue from the prior year, as reported to ENR by firms that choose to participate. Gensler co-CEOs Diane Hoskins and Andy Cohen highlight an “understanding of the connection between design, business, and the human experience,” along with a commitment to employees and work culture, as essential to robust growth.
