While The WA100, Building Design’s annual ranking of the world’s largest architecture firms, isn’t perfect (see our controversial article here), it does reveal a lot about the state of architecture today. And for 2013, the research shows that there are finally brighter days ahead for architects – just not at home. BD’s research reveals that China remains the world’s largest construction market (a title it’s held since 2010); that the Asia-Pacific Market is expected to be the largest by 2020 (with projected value of $4.6 trillion dollars); and that China, India, and Brazil offer the best growth potential for architectural services. Not surprisingly, the survey’s top three ranking firms – Aecom, Gensler, and IBI Group – all have a significant presence in these markets. However, are these mega-firms really the best models to aspire to? With the economic crisis making it everyday more evident that there are more opportunities abroad than at home, where is a firm to go? China? India? Brazil?
