Site records
Planned nine-building Microsoft datacenter campus near Durand Avenue in Mount Pleasant, Wisconsin, on a 791-acre parcel Microsoft says it bought in 2024. Village planning documents reported by WPR describe 5.2 million sq ft of development, including a 96,000 sq ft office and other related buildings, with an estimated taxable value of more than USD 7.97 billion. The plan commission recommended the site plan with conditions on traffic and water use, and the village board approved it unanimously in January 2026. Microsoft's construction page reports preliminary earthwork under way since March 2026 at a Phase 3 site at Durand Avenue and Hewitt Memorial Drive.
