Designed by David R. Jones in Second Empire style, this house at 104 Langdon Street in Madison, Wisconsin, was built in 1878 for the distinguished law professor, state assembly representative, and US district judge Romanzo Norton Bunn and his wife Sarah Purdy Bunn (see the Property Record online). Two Second Empire-style towers were removed in 1925, resulting in a modified roofline, and the house was divided into apartments.

The building features a buff brick exterior, vinyl one-over-one replacement windows, a cornice with brackets, mansard roofs with low-slope upper portions, dormers with vaulted roofs, a wrap-around front porch with Doric columns, an open pier foundation, and a hipped roof, a shorter rear ell with a decorative Victorian porch, a two-story oriel window on the Carroll Street facade, a tower in the middle of the Langdon Street facade with a wrought iron balcony on the second floor and a front door at the base with a transom, and a two-story bay window at a 45 degree angle to the rest of the house at one corner of the front facade.
