Houses in Sullivan County, New Hampshire

The Louis St. Gaudens House and Studio is a historic house at Dingleton Hill and Whitten Roads in Cornish, New Hampshire. The 2-1/2 story gambrel-roofed wood frame structure was designed by Moses Johnson and built in 1793-94 at the Shaker village in Enfield, New Hampshire. At that site the building served as the main meeting space for the Shakers, with a main meeting space on the ground floor, offices on the second floor, and guest living quarters in the attic space. The building is similar in construction to buildings designed by Johnson for the Shaker villages in Canterbury, New Hampshire and Sabbathday Lake, Maine.

The Protectworth Tavern, also known as the Stickney Tavern, is a historic house on New Hampshire Route 4A in Springfield, New Hampshire. It is a nearly-intact example of a late-Georgian early-Federal vernacular house, dating to the time of the construction of the "Fourth New Hampshire Turnpike", a major early highway through this region of central New Hampshire whose route is followed here by Route 4A. The house was long used as a tavern, and one of its early owners was Daniel Noyes, a proprietor of the Turnpike. Meetings of the Turnpike's owners are known to have taken place here. A later owner, Nathaniel Stickney, was also a stagecoach driver on the route.

The Nettleton House is a historic house at 20 Central Street in Newport, New Hampshire. The two-story brick structure was probably built in the 1830s, since it exhibits a commonality of materials and construction techniques with the nearby former county courthouse, which was built in 1824. It was probably built by Joel Nettleton, and is referred to in deeds as the Nettleton homestead. Nettleton operated a tavern and stage coach. The house is now home to the Newport Historical Society Museum.

Salmon P. Chase Birthplace was the birthplace and childhood home of Salmon P. Chase. It is located about 8 miles (13 km) north of Claremont on New Hampshire Route 12A. The ​2 ⁄2-story wood frame house was built c. 1790, and is a multi-section structure in an L shape. The main block is five bays wide and two deep, with a centered entry that has Greek Revival pilasters on the central entry and on the corners. This block faces west, and two narrower sections extend east from the rear. The first of these sections is also ​2 ⁄2 stories, with two chimneys. The easternmost section is 1-1/2 stories, and was originally connected to a barn. The house is believed to be well-preserved, but there is no documentary evidence of its appearance in the early 19th century, and it is known to have been moved across the street from its original site in about 1848.

The Isaac Reed House is a historic house at 30-34 Main Street in downtown Newport, New Hampshire. The 2-1/2 story wood frame house was built c. 1869 by Dr. Isaac Reed, a local dentist, and is an important visual element of the municipal/county cluster of buildings which stand immediately adjacent. The house is Second Empire in style, with a mansard roof punctured by dormers with central segmented-arch roofs. The main facade is nominally three bays wide, although the first floor is divided in two, with a porticoed entry to the left and an ornately bracketed bay window to the right. There was originally an unsympathetic addition to the rear, which was built to make the building a multi-unit residence; this was removed in the 1970s, when the town decided not to raze the property.

The William Rossiter House is a historic house at 11 Mulberry Street in Claremont, New Hampshire. The main block of this multi-section house was built in 1813 by Austin Tyler, and retains some elements of Federal style. An ell was added, and the house given extensive Greek Revival treatment, c. 1830-50 by William Rossiter, a prominent local businessman and politician. Prominent in these alterations was the addition of a full Greek temple front, complete with two-story columns and a projecting triangular gable pediment. A garage was added to the rear early in the 20th century.

Saint-Gaudens National Historical Park in Cornish, New Hampshire, preserves the home, gardens, and studios of Augustus Saint-Gaudens (1848–1907), one of America's foremost sculptors. The house and grounds of the National Historic Site served as his summer residence from 1885 to 1897, his permanent home from 1900 until his death in 1907, and the center of the Cornish Art Colony. There are three hiking trails that explore the park's natural areas. Original sculptures are on exhibit, along with reproductions of his greatest masterpieces. It is located on Saint-Gaudens Road in Cornish, 0.5 miles (0.80 km) off New Hampshire Route 12A.

The David Dexter House is a historic house on Lincoln Heights in northern Claremont, New Hampshire. This large, five-by-four bay wood frame 2-1/2 story house was built c. 1790 by David Dexter, who along with his brother Stephen was responsible for significant growth of the textile mills in central Claremont. The house was later used as a boarding house for mill workers. In the 1970s the house became the focal point for a long-running preservation debate, whose result was that the building was relocated to its present location, minus a later ell and its original central chimney, in 1975, to make way for an urban redevelopment project.
