It’s become an almost weekly occurrence this summer: a leading architecture practice acquiring a smaller firm to give itself additional capabilities or a presence in a new market. This week’s deal sees Perkins+Will buying Rozeboom Miller Architects. Terms of the transaction, which was announced yesterday, are undisclosed.

Based in Atlanta, the 72-year-old Perkins+Will is a leader in sustainable design, educational facilities, and health care buildings. It maintains offices in 16 cities nationwide—many the result of past acquisitions—as well as additional offices in Canada and China. Posting $268.3 million in revenue last year, Perkins+Will ranked No. 5 on RECORD’s annual list of the Top 150 Architecture Firms.

Rozeboom Miller, meanwhile, was established 10 years ago in Minneapolis and specializes in K-12 design as well as civic and cultural buildings.
