Global bioscience company Chr. Hansen Inc. is planning to soon begin demolition work to make way for a 20,000-square-foot, $25 million expansion at its North American headquarters in West Allis.

Company officials announced the expansion plans Wednesday at its facility at 9015 W. Maple St. They said the project would result in about 25 to 30 new jobs within the next couple of years.

Specifically, Chr. Hansen’s food culture’s and enzymes facility would be expanded west of the existing building footprint. To make way, the company will within the next couple of weeks begin demolishing the former Knights of Columbus building located directly west of the facility and east of South 92nd Street. Demolition work will continue through the rest of the year.
