Collaborative Design Group Creative Thinking... Thoughtful Solutions
Eddy Hall

Eddy Hall is the oldest building on the University of Minnesota Twin Cities Campus, and is listed in the National Register of Historic Places as part of the Old Campus Historic District.

Collaborative Design Group was chosen by the University to complete a pre-design study to understand the logistics, code consequences, and effect on performance of the historic building resulting from the removal a non-historic metal addition/annex to this highly sensitive building, as well as to assess the building’s current condition. The pre-design analysis included a forensic examination of the exterior envelope and probable construction cost estimates to support removal of the annex located on the west side of Eddy Hall. The pre-design analysis also identified work necessary to meet current building code requirements for accessibility and fire/life safety.

Significant investigation for the restoration of the existing building’s west facade, and adjacent west site (once the metal annex building is removed) was included in the work effort. The related restoration design was developed to meet Secretary of the Interiors Standards for the Treatment of Historic Properties.
