Just because the construction market may be slow doesn’t mean companies, including architectural firms, can’t continue to grow. Just take a look at Inc. Magazine’s 2010 Inc. 5000 List of America’s Fastest Growing Private Companies, which includes several architectural firms.

According to Inc., the list measures revenue growth from 2006 through 2009. To qualify, companies must have been founded and generating revenue by June 30, 2006. The minimum revenue required for 2006 is $80,000; the minimum for 2009 is $2 million.
