Eighteen Mile House

Roudebush Farm is a historic farmstead located southeast of Harrison in northwestern Hamilton County, Ohio, United States. It was established in the 1850s with the construction of a small frame residence. This building, the original farmhouse, was built just one story tall and composed of two rooms. The builder was the farm's namesake, Hammand Hersh Roudebush.A native of Adams County in southeastern Pennsylvania, Roudebush and his parents settled in Ohio in 1834 when he was just four years old. Twenty-five years later, he and his wife Emeline bought a Harrison-area property known as "Sand Hill" and settled there; this became the present Roudebush Farm. After completing the original farmhouse and barn in the same year, the Roudebushes became prosperous enough to expand their buildings, and accordingly they expanded the house greatly in 1870. No longer was the house simply a small frame structure: the addition is built of brick with many ornate Italianate details and multiple fine porches. Among the most distinctive elements of the house is its elaborate formal parlor, which retains the furniture, silk wallpaper, and carpet with which it was furnished in 1875.In 1976, the Roudebush Farm was listed on the National Register of Historic Places, qualifying because of its historically significant architecture. Four contributing properties are included within the 9 acres (3.6 ha) of property designated as historic, including the farmhouse, the barn, and a schoolhouse, although the schoolhouse is no longer used for educational purposes.

The George Bennett House was a historic residence built near the city of Harrison, Ohio, United States. Constructed during the middle of the nineteenth century, it was a prominent building along one of the area's major roads, and it was eventually named a historic site. George Bennett was among the first men of the Harrison area during the middle of the nineteenth century. Besides his wealth, which was equalled by few men in the area, his prominence derived from his politics: he gained a reputation as a premier lobbyist. Bennett also occupied a leading place in the society of northwestern Hamilton County, and his home was widely known for its numerous social gatherings as well as the political events that were held there. He arranged for the construction of his house in 1847, employing an unknown architect to produce a simple design in the Greek Revival style.Two stories tall, the house was highly symmetrical, with a central section and a wing on each side of a size comparable to the center. All three segments of the facade were divided into three bays each, with the main entrance in the central bay of the central section. Each of the remaining seventeen openings was filled with a window, although the second-floor windows on the wings were substantially shorter than the windows of the central section and of the first-floor windows of the wings. Framing the ends of the building were two chimneys, with one on the roofline at each end of the house, while the center was marked by a simple four-pillared portico sheltering the entrance and permitting the central section of the house to have a substantial overhang. All roofs were gabled, and the projection at the center of the facade was topped with a pediment under the roof. Constructed on a stone foundation, the house was built with walls of mixed brick and wood, and in its last years, the house was given a tin roof. Bennett's frequent parties necessitated the reservation of a large space on the second floor for use as a ballroom, with its floor supported by springs according to oral tradition, although collapsible screens permitted its conversion into dormitory space when necessary. The overall plan bears similarities to various structures designed by Thomas Jefferson, but the Bennett House's adherence to the later Greek Revival style was solidified by its lack of complex design elements.Due to its large size and distinctive architecture, which were accentuated by its location on the Harrison Pike, the Bennett House was long a landmark for local residents and travellers. In mid-1975, its status was further raised by addition to the National Register of Historic Places; qualifying because of its distinctive historic architecture, it was the first Harrison-area building to acquire this designation, although the Othniel Looker House was listed one week later, and four more houses followed by the end of 1976. Despite its landmark status, the house no longer occupies its place; the site is now an empty lot.

The Jehu John House was a historic house and school building in the far southwestern part of the U.S. state of Ohio. Located in the city of Harrison near Cincinnati, it was one of the area's earlier buildings and home to one of its most prominent residents. Although it was named a historic site in the 1970s, it has been removed. Born in 1796, Jehu John, Jr was an early physician in Hamilton County who made himself rich by producing and selling a medicine for fevers, which became highly popular. With his finances assured, he abandoned the practice of medicine and devoted himself to education, opening a school in his house in late 1847. The house was built on land belonging to the family of Ohio Governor Othniel Looker, whose granddaughter Emily had married Jehu John in 1828.Built in a combination of brick and stone with a tin roof, the John House was a simple one-and-a-half-story house with narrow gabled ends and a wide front; no windows were placed on the ends, while the front featured a doorway with two windows on each side. The basic floor plan was that of the letter "T", with the long end to the rear.One of southwestern Ohio's best stone residences from the settlement period, the Jehu John House was listed on the National Register of Historic Places in late 1975; it qualified both because of its connection to John and because of its important architecture. Despite this designation, the house no longer occupies its location on Stone Drive; a newer building has taken its place.
