With a record-breaking number of skyscrapers and new developments changing the identity of cities around the world, architects have never been busier. As worldwide architecture and design firms continually expand their footprint across international borders, their global reputation correspondingly receives a boost. Some of that increased attention is expressed through the media, particularly Building Design Magazine, whose annual survey of the largest companies — ranked by the number of fee-earning architects — celebrates the accomplishments of the world's leading architecture and design practices.

The 2017 World Architecture Top 100 list is a who's who of the prominent talent shaping the urban fabric of the world's cities today. With 2,570 architects employed, 1,000 more than just two years ago, American firm Gensler dominated the rankings. Their sustained work in 46 geographical locations has been bolstered by projects in North America, which has continued to be a source of strength for the practice. Shanghai Tower, Le Phare de Québec, and Metropolis are among their most significant developments.

Japan's Nikken Sekkei placed second in the list with 1796 architects employed, progressing their reputation as the Pacific Rim's dominant architect. A slowing Chinese economy has sent the group to other Southeast Asian markets including South Korea, Malaysia, and Indonesia. 2016 also saw the firm's breadth stretch to India and Europe. Meanwhile, AECOM's good fortunes continue, landing them third on the list. The American practice has seen steady growth in the infrastructure sector, with the Olympic site and venues of the 2016 Summer Olympics in Rio doubling as a priceless global advertisement of their work. At fourth and fifth are Perkins + Will and HDR, both based in the United States. Sixth and seventh respectively, IBI Group and Woods Bagot are the only Canadian and Australian practices finding a place in the top ten. HOK, Aedas, and DP Architects take the remaining spots.
