Landmark Preservation reviews the designs of proposed exterior alterations, additions to buildings, new construction, signs, and non-vegetative site work for properties located within the boundaries of an historic district or for a property designated a Denver landmark. Design review ensures that a proposed project preserves key historic features and is compatible with the character of designated historic buildings, sites and districts.
The Landmark Preservation Commission, the Lower Downtown Design Review Commission, and Landmark Preservation staff use design guidelines and the Secretary of Interior’s Standards for the treatment of historic properties to guide design review. Additional guidelines may apply for projects located in specific historic districts.
