An unbracketed Italianate style with American federal detailing, it was built by U. S. Representative Bernhardt Henn. In 1894 it was sold to the Presbyterian Church for use by Parson's College.

MUM purchased the campus in 1974 and began extensively restoring the mansion in 1984, before it would have totally collapsed.

Among other work, replications were made of molded plaster ceiling medallions and long-lost woodwork.

The entrance gates and Foster Hall are the only remaining structures of the Henry K Holsman Historic Campus District, also listed on the National Register of Historic Places. More information at the Prairie Architects website.
