 Its significance is derived from its association with the Danish immigrant settlement of the community, and the skilled Danish craftsman who lived and worked there.

 They were natives of Fyn, Denmark who immigrated with the rest of their family to Wisconsin in the 1870s before settling in Audubon County.
 Built in 1894, the 1½-story frame structure features a T-plan, wall dormers, and a small square tower.
 The original front porch has subsequently been replaced by an enclosed porch.
 The house was built for Jens Larsen, also a Danish immigrant.

 The southern half of Kimballton was his land.
 This was his retirement home, and he lived here until he died, as did his wife Elena who died in 1928.
