The John K. Voorhees House is a historic building located northwest of Oskaloosa, Iowa, United States. A native of Warren County, Ohio, Voorhees settled in Mahaska County in 1853. He owned 400 acres (160 ha), and was considered a leading farmer in the county.[2] He was known for his horses and Black Angus cattle. Voorhees had this house built in 1871, and he supervised the work that was done by masons and carpenters. It is a combination of the Italianate and Second Empire styles. The 2½-story, brick structure follows a T-plan. It features a mansard roof, bracketed eaves, limestone quoins on the front, brick quoins on the back, and a full sized wrap-around front porch. The east section of the original porch and the balustrades on top had been removed.[2] They have subsequently been recreated. The house was listed on the National Register of Historic Places in 1982.[1]
