The Studabaker-Scott House and Beehive School are two historic buildings near the city of Greenville in Darke County, Ohio, United States. Located along State Route 49 south of the city, both are unusually well-preserved remnants of the architecture of the middle third of the 19th century. A native of Pennsylvania, Abraham Studabaker settled in Scioto County, Ohio in 1795; after moving northwest to Warren County, he travelled north and built a cabin in modern-day Darke County in 1808,: 253  becoming the first settler within the present boundaries of Adams Township.: 417  From the county's earliest years, Studabaker was a prominent member of local society; when Darke County was formed in 1816, he was elected to the county commission. Moving to Greenville Township in 1815,: 238  he built a larger homestead in 1835, but it was a simple structure like that of most period houses. In the 1850s, many former pioneers began to expand their homesteads: as prosperity increased, landowners renovated their old houses according to the prevailing architectural styles of the day. Studabaker followed this pattern; his old farmhouse took on a mix of the Early Victorian and Greek Revival architectural styles, and its location along one of the county's most important roads gave his house a prominence enjoyed by few other houses in the area.Located very close to Abraham Studabaker's house is the Beehive School. Built in 1846, it was one of the earliest permanent school buildings — in contrast to the primitive log structures built by the first settlers — in Darke County. Unlike the Studabaker House, this brick building features elements of the Federal style of architecture.In 1978, the house and school were listed on the National Register of Historic Places. Although the two buildings both qualified for inclusion on the Register, they and a third contributing building were listed together as a single property. Key to their being listed on the Register was their well-preserved historic architecture and their connection to Abraham Studabaker, because of his place as one of the region's leading pioneers.

The Donovan Robeson House is a historic house in Greenville, Ohio, United States. Located along Fourth Street west of downtown, the Robeson House has been ranked as the city's most significant Queen Anne mansion.

The Waring House (also known as the "Waring-Stockslager Home") is a historic house in Greenville, Ohio, United States. Built by Oliver C. Perry, the house was started in 1860, but construction was only substantially completed in 1869, and the details took two more years to finish. As soon as he had finished the house, Perry sold it to T.M. Taylor, who in turn sold it to the family of local businessman and county commissioner Thomas Waring. Waring and his family were the first individuals to occupy the house, taking up residence in November 1874. The Waring House is a brick structure that rests upon a foundation of stone; it is topped with a roof of asphalt, and various other elements are made of metal. Its overall floor plan is rectangular, although modified by the addition of three wings to the rear. The dining room is a major part of a substantial two-story, two-bay wing attached to the main portion of the house, while two single-story wings — a single-bay structure in the form of a large pavilion, and a double-bay structure containing the kitchen — are in turn attached to the dining room wing. Among the Waring House's leading architectural elements are its windows, especially the distinctive segmental windows of the dining room wing. Overall, the house is a fine example of the Victorian style of residential architecture; although many nineteenth-century Greenville houses have been well preserved to the present time, few are as pristine as the home of Thomas Waring. In recognition of its historically significant architecture, the Waring House was listed on the National Register of Historic Places on September 16, 1977; it was recognized as important primarily in the local community. Six other Greenville houses — known as the Beir, Coppess, Garst, Lansdowne, Leftwich, and Robeson Houses — have been accorded a similar honor; the Waring House was the fourth of these seven buildings to receive this designation. Today, the Waring House is operated as a bed and breakfast.

The Leftwich House is a historic house in Greenville, Ohio, United States. Built in 1875, the house features a combination of the Italianate and Stick-Eastlake styles. A frame structure built upon a foundation of stone, it was one of the most well-preserved Stick-Eastlake houses in Greenville and the surrounding area, with a porch that has been described as "outstanding" and a gable that is ornamented by specifically Stick elements. Unfortunately, as of May 2021, the house has fallen into disrepair, with shutters hanging askew or missing, the exposed wood is noticeably rotting and exterior paint peeling and bubbled all over. The house's floor plan is unusual; its four-bay western facade is divided between two components of two bays each; through the northern component, one may enter the house through a Victorian front door. An Eastlake porch shelters the rear door that opens onto the protruding kitchen, and various eaves elsewhere on the exterior form separate cornices, each of which is composed of brackets and a frieze. Covering the house is a hip roof, which consists primarily of shingles. In 1975, the Leftwich House was listed on the National Register of Historic Places because of its excellent architecture. Although the house's history included no distinctive events or residents, its architecture was rare enough to qualify it for listing.
