GSA endeavors to preserve these national treasures for future generations through building investments, reuse strategies, and employing cutting edge design efforts.
The Rocky Mountain Region’s real estate inventory features many properties that are rich in significant American history, architecture, art, engineering, and culture. GSA’s historic preservation program provides technical and strategic expertise to promote the integrity, viability, and reuse of historic buildings owned and leased by GSA.
