Architects present schematic plan for Corn Palace renovation, estimate ~$18–20M and phased construction

Schremmer Associates presented a schematic concept for a significant renovation and limited expansion of the Corn Palace to the Mitchell City Council on June 16.

The design team, represented by Robin Miller, described two phased approaches that would replace aging mechanical, electrical and plumbing systems, increase usable event floor area and add seating and donor/display spaces while preserving or reusing historic corn murals where possible. The firm estimated the project at roughly $18 million in present‑day dollars and noted a range to about $20 million when accounting for mid‑construction inflation and market conditions.

Design goals and approach

The architects said the Corn Palace currently contains underused vertical volume above the arena floor and that modern HVAC and electrical systems are nearing the end of their useful life. The recommended schematic would add approximately 12,500 square feet of event floor area and reconfigure seating with a combination of fixed and retractable risers to gain capacity and flexibility. Under the design the council reviewed, the Corn Palace’s seating would increase substantially (the presentation reported a net gain of roughly 1,000 fixed seats plus retained seating options on the stage, with a total seat capacity to be finalized by a seat‑manufacturer count during later design phases).

"We looked at options that minimize downtime and options that let you keep operating while we build," said Robin Miller, the project architect. The design committee favored a phased option that locates new mechanical rooms to the north of the existing building so much of the facility could remain in use during construction; an alternate approach with more demolition would take the venue offline for longer but would reduce some costs.

Phasing, schedule and next steps

Schremmer Associates proposed a path through design development and construction documents to a bidding and construction phase. The firm estimated that a detailed design and permitting schedule could run through early 2026, bidding in mid‑2026 and phased construction through 2027–2028, with limited closures staged to preserve some Corn Palace operations during the work. Miller emphasized that the project team still needs historic records and structural details from older renovations to refine the plans and costs.

Cost and fundraising

The schematic presentation included a high‑level cost estimate: approximately $18.08 million in the firm’s calculation, with staff noting the practical bid‑market midpoint could push the figure toward $20 million by the time of construction. Council members and staff discussed potential donor interest and next steps; the council did not vote to proceed beyond the schematic presentation but was told Schremmer Associates could be contracted for the next design phase if the council decides to move forward.

Why this matters

The Corn Palace is a major visitor attraction and community asset in Mitchell; the presented work would modernize systems, expand event capacity and create more donor and interpretive display space while preserving much of the building’s historic character. A final decision on design, contract awards and funding would belong to the council in later agenda items if councilors choose to pursue design development.
