ARCHITECT Magazine has released their fourth annual ranking of the most “powerful, philanthropic, talented and profitable” architecture firms in the United States. Don’t be fooled, this doesn’t necessarily mean the biggest firms, as the survey uses the broadest possible criteria to allow practices, both small and large, the opportunity to compete and be recognized.

Firms are ranked by profitability, sustainability and design quality. For the first time this year, the survey included pro bono work and water modeling in response to the challenging realities of the economy, natural disasters and drought.

Additionally, the survey revealed that 66% of the firms reported an increase in their net revenue from 2010 to 2011. No surprise there, when considering the slow, overall improvement of the ABI (check out the latest ABI report here).
