Built for Hermann Christian Timm and his wife, Augusta (Muenster) Timm, this house was erected in two sections. A frame, Greek Revival-influenced residence was built for the Timm family in 1873. In 1892, a large stick style house was constructed onto the front of the earlier house. August F. Neuman, a contractor from Kiel, built the new plan and carried out the remodeling of the original home. Herman C. Timm arrived in New Holstein in the summer of 1848, and in 1864 married Augusta Muenster. The couple had seven children who lived to adulthood. Mr. Timm was the first president of the village of New Holstein, owned the H. C. Timm Elevator Company, served as president of the State Bank of New Holstein and was president of the New Holstein Mercantile Company. The house remained in the Timm family until 1974, when Herman C. Timm II, the son of H.C. and Augusta Timm gave the house and most of its contents to the New Holstein Historical Society. The house was listed on the National Register of Historic Places in 1996, in recognition of its architecture.
