Architectural Collections

The Special Collections and Archives Department collects the drawings and project files of significant regional architects. A listing of the Department's major architectural collections appears to the right and links to each collection's catalog record and finding aid (a guide that provides a detailed description of a collection's contents). 

Please note that DPL does not hold floor plans or architectural drawings for all Denver buildings. 

When searching within architects’ collections, in cases where you find mention of a structure but no drawings are listed, researchers will want to review project files and other materials that may have additional relevant information to their project. These items may include correspondence, contracts, sketches, photographs, and folded drawings, among other items.

Additional architectural collections can be found by searching the Denver Public Library's catalog or archives finding aids index. Please note that architectural collections that do not have a finding aid may have an inventory available. Contact the department for more information.

Please visit the Research Services and Access page for more information on:

A few best practices for handling architectural and design drawings in our research room:

• Wash hands with soap and water before you enter the research room. Hand sanitizer is not recommended. Gloves are not permitted, as they increase likelihood of tearing fragile materials.
• Gently slide drawings to the side as you finish with each one, maintaining the original order of the materials. It is likely that drawings were arranged intentionally by project and drawing function.
• Ask a librarian or archivist for assistance moving folders or rolling any drawings.
• Please do not place anything on top of collection materials.

Please note that interior floor plans of existing, privately-owned buildings require permission from the current owner of the property/building before permission can be granted to photograph, photocopy or scan the item.

It is the customer's responsibility to locate the owner and obtain written permission.
