Horner–Terrill House, Second Empire residence in Indianapolis, United States.

The Horner-Terrill House is a two-and-a-half-story brick structure adorned with limestone details and distinguished by a three-story tower on the south facade. The composition combines Second Empire style elements with solid construction typical of high-quality residential architecture from that period.

Built in 1875, the house emerged during Indianapolis's period of rapid expansion when prosperous families were establishing new residential neighborhoods. This structure reflects the economic growth and building ambitions of a city transforming into a major Midwestern center.

The residence displays Second Empire characteristics with its mansard roof and rounded arches, reflecting the taste of prosperous homeowners in the 1870s. These design choices signaled wealth and fashionable sensibilities among Indianapolis residents of that era.

The residence sits in an established neighborhood and is viewable from the street, allowing visitors to appreciate the exterior architecture and design details. Access conditions and visiting arrangements depend on current owner policies and may vary by season.

The property includes a contributing garage built around 1930, a separate structure from the c. 1875 house. It is part of the National Register listing made in 2013, which covers both the dwelling and this outbuilding.
