In the three years leading up to the current recession, gross billings at U.S. architecture firms increased nearly $16 billion from 2005 and totaled $44.3 billion in 2008. That equates to 54 percent growth over three years with annual growth of about 16 percent.

These findings come from the American Institute of Architects (AIA) “Business of Architecture: AIA Survey Report on Firm Characteristics,” which is conducted every three years to examine issues related to the business practices of AIA member-owned architecture firms.
