Breaking ground: Irgens Partners’ mixed-use project in Wauwatosa

Milwaukee-based Irgens Partners LLC plans to transform a 13.9-acre office building site in the Milwaukee County Research Park into a mix of uses.

The redevelopment effort will involve renovating an existing 130,000-square-foot office building at 10701 Research Drive. Next steps include construction of a new 43,000-square-foot medical office building along North Mayfair Road, an 8,000-square-foot retail building southeast of Research Drive and Mayfair and 185 new apartment units northeast of East Wisconsin Avenue and Mayfair.

Irgens revealed details of its mixed-use project in December after buying the site in August for $9.5 million and advancing plans in November to divide the property into smaller lots.
