The transformation of Duluth’s Old Central High School into Zenith DCHS is an example of how historic architecture can be successfully repositioned for modern residential life. A landmark since 1892, the massive 130-year-old structure required a sophisticated design approach to convert institutional spaces into a cohesive 122-unit apartment community.

As both the Architect and Historic Consultant, AWH navigated the complexities of preserving the building’s iconic red sandstone from the Krause Quarry in south Duluth and 230 foot clock tower while completely reimagining its interior. Our dual role allowed us to integrate rigorous preservation standards directly into the design process, saving the client both time and money.

The project brought the auditorium back to its original configuration and repurposed it as an indoor residential hub play area including two pickleball courts. Other amenities include a fitness center, sauna, workshop/maker space, Dean’s Lounge which was restored from the original principal’s office and is available for residents to gather, play a board game and reminisce about visiting the principal’s office.

The project’s success relied on our team’s ability to modernize the building’s core infrastructure without compromising its historic character. From the restoration of the grand corridors to the strategic placement of modern amenities, every intervention was designed to honor the building’s legacy while meeting contemporary standards.

The result demonstrates the value of an integrated design and historic consulting process. By applying deep expertise in adaptive reuse, AWH helped transform an underutilized civic icon into a vibrant and sustainable residential destination that defines the Duluth hillside.

The project leveraged nearly $4M in Tax Increment Financing from the Duluth Economic Development Authority with approximately $19M in historic tax credits to support the redevelopment.

The project hit 50% lease up within the first two months with nearly full lease up within the first year and continues to maintain a high occupancy rate.
