At the June 3 meeting of the Loudoun County Board of Supervisors, the Loudoun County Design Cabinet, in partnership with the Department of Economic Development, proudly announced the winners of the 2025 Signatures of Loudoun Design Excellence Awards. This year marks the 20th anniversary of the program, which has recognized and elevated outstanding design across the county for two decades.

“Every great community is built with intention,” said Buddy Rizer, Executive Director of Loudoun Economic Development. “By honoring these outstanding projects, we’re also supporting a vibrant economy, celebrating local talent, and reinforcing the unique character of our community.”

To commemorate the 20th anniversary, Loudoun Economic Development created a special edition Signatures of Loudoun book, highlighting two decades of award-winning design across Loudoun County. An interactive digital version of the commemorative book can be found at SignaturesofLoudoun.com.
