As promised, we're providing some additional previews of some of the numerous rankings we're publishing in our upcoming Top Design issue. We've already posted a preview of the main ranking. For breakout rankings, we'll start with the top 25 firms for the state of Florida.

This breakout ranking is based upon the amount of design revenue each firm generated during the 2008 calendar year from projects located in Florida. Together, the top 25 design firms listed here reported more than $1.6 billion in 2008 design revenue from the state of Florida. All figures are in millions.
