The Milwaukee Public Museum’s long-planned move to a new downtown home just got very real. Museum leaders told Milwaukee County officials on Tuesday that they have now raised more than $212 million toward the project’s roughly $240 million budget, putting the future Nature & Culture Museum of Wisconsin solidly within reach of its early 2027 opening target.
Funding Pace
According to Urban Milwaukee, the $212 million figure shared at a Milwaukee County Board parks and culture committee meeting on March 3 combines $127 million in private donations raised since groundbreaking with $40 million from the State of Wisconsin and a $45 million commitment from Milwaukee County. The outlet also reports that 47 donors have stepped up with gifts of $1 million or more.
What the Project Will Look Like
As outlined by the Milwaukee Public Museum, the new Nature & Culture Museum of Wisconsin will be a roughly 200,000-square-foot, five-story facility next to the Deer District, supported by about 50,000 square feet of offsite storage to house portions of the collections. The museum’s project FAQ notes that the original budget called for about $200 million for the building and $20 million for an endowment, bringing the total project cost to around $240 million. Construction began in summer 2024, with work scheduled to wrap up in late 2026 and doors opening to the public in early 2027.
Donors, Costs and a Note on Inflation
At the county meeting, MPM Executive Director Ellen Censky told supervisors that “So we have seen strong support from major donors and public partners, and the momentum continues to build,” while also cautioning that inflation has nudged project costs up by roughly 6% since it began. “I will say, based on our contract with you, we will not be coming back to the county for that,” Censky added, as reported by Urban Milwaukee. Parks committee chair Sheldon Wasserman called the fundraising tally “a spectacular number.”
Construction Update
Mortenson crews are visibly reshaping the corner of Sixth and McKinley, where a topping-off ceremony recently marked a key moment in the rising steel frame. As reported by TMJ4, exterior construction is expected to be finished by the end of 2025, with interior buildout and exhibit installation continuing through 2026.
Old Building's Future
Back on Wells Street, the existing museum complex is likely nearing the end of its run. County consultants have advised demolishing the roughly 3.7-acre site and marketing it for mixed-use redevelopment, estimating demolition costs in the low tens of millions and finding that option far cheaper than attempting adaptive reuse. The consultant team of GRAEF, Bear Real Estate Group and CG Schmidt concluded that full demolition would open the door to higher-density housing and a stronger tax base, with concept plans showing as many as about 555 residential units, according to reporting by Daily Reporter.
Collections And Next Steps
MPM says the relocation will mean carefully packing and transporting roughly four million objects and specimens. Non-collection items are slated to be offered first to county departments and affiliated organizations, then to other museums and nonprofits, and finally made available at public auction. The museum also plans to launch a public phase of fundraising focused on smaller donors this fall, while staff continue packing existing exhibits and securing long-term storage for portions of the collection, according to the Milwaukee Public Museum.
Fundraising is expected to continue as leaders finalize exhibit design and detailed packing plans, and county staff prepare to bring the Wells Street property to market next year. If those timelines hold, Milwaukee residents will be walking through the doors of the new Nature & Culture Museum of Wisconsin in early 2027.
