Herman C. Timm was a successful New Holstein grain merchant. His accomplishments began with the construction of the first of three grain elevators in 1879, expanding business in the town. He was also elected as the first president of the village of New Holstein in 1901 and founded the State Bank of New Holstein the very next year. In 1872 he built a modest, single story, side-gable house near his granary. After many years as a successful businessman, Timm hired August F. Neuman to remodel. While incorporating the original structure, he turned the property into an elaborate residence that reflected Timm's prominence.

The house is an example of the Stick Style, which is uncommon in Wisconsin. The style is known for its patterned and paneled surfaces, featuring many stick-like details. It was built in Wisconsin between 1870 and 1890, but few true examples remain. The Timm House demonstrates influence of the Queen Anne on the Stick Style. This example has a prominent corner tower and incorporates the use of stick-sheathed walls and restrained wood details with geometrically patterned surfaces. The unified stick patterning is extended into the multi-paned stained glass windows typical to Queen Anne.

The Herman C. Timm House was occupied by his two daughters until 1974. The house was donated to the New Holstein Historical Society along with its original furnishings. It is open to the public during scheduled tour hours.
