Mount Vernon Tavern: The Mount Vernon Tavern, also known as the Bank House Tavern, is an historic house in Foster, Rhode Island.  It is located at 199 Plainfield Pike (Rhode Island Route 14), about 3/10 of a mile east of its junction with Howard Hill Road.  The main block of the house, a 2-1/2 story wood frame structure with gable roof, was built c. 1760, and was originally attached to an even older structure which was demolished in the late 19th century.  This main block, five bays wide with a central chimney, is attached to a 1-1/2 story gable-roofed ell to the west.  The main entrance portico features unusually elaborate Federal styling for a rural location, and was probably added in 1814.

John Adams Homestead-Wellscroft: The John Adams Homestead/Wellscroft is a historic farmstead off West Sunset Hill Road in Harrisville, New Hampshire.

It is one of the least-altered examples of early Cape style architecture in Harrisville, lacking typical alterations such as the additions of dormers and changes to the window sizes, locations, and shapes.  The only notable alteration is to the front door surround, made c. 1825 when an ell was also added to the house.  One of the upstairs rooms also has stencilwork on its walls that may be the work of folk artist Moses Eaton, Jr., a Harrisville resident.  Among the surviving outbuildings is a barn dating to the early 19th century.  The property's name, Wellscroft, derives from an early 20th century summer residence that was built in the property, and torn down in the 1970s.

In 1900 it was purchased by Wellington Wells, who converted it into a summer residence, adding the front porch, dormers, and garage.  The property also includes a barn, which is believed to date to the 18th century.

Rice City Historic District: The Rice City Historic District is a historic district in Coventry, Rhode Island.  It encompasses the 19th-century village of Rice City, extending along Plainfield Pike (Rhode Island Route 14) for several miles between Sisson Road and Gibson Hill Road in the northwestern part of Coventry.  The main village center is at the junction of the Pike and Vaughn Hollow Road, and there is a former industrial and commercial center at Fairbank's Corner, the junction with Flat River Road (Rhode Island Route 117).  The architecture of the district is predominantly rural and residential, with Greek Revival and Federal style housing predominating.  Rice City village is dominated by Rice Tavern (built 1804), which used to serve travelers on their way to Connecticut, as well as the Rice City Church (1846), the Democrat Schoolhouse, and the Obadiah Potter House (1846), all a short way up Vaughn Hill Road.  At the western edge of the district, the modern Pike alignment diverges from the historical one at Gibson Hill Road, where the foundational remnants of agricultural settlements may be found.

William Stevens House (Clinton, Connecticut): The William Stevens House is a historic house at 131 Cow Hill Road in Clinton, Connecticut.

The rear of the house has a leanto section, giving it a saltbox appearance, from which a modern single-story addition extends further.  The house's construction date is uncertain: it is usually attributed to William Stevens (1630-1703), placing it in the late 17th or early 18th century.  The house is distinctive in part because of an extremely non-standard floorplan.  Instead of a tight winding stair in the front vestibule, the chimney in the house is set further back than normal in houses of the period, and the stair rises via a dogleg and straight run to the chimney's left.  Conventional houses of the period of fireplaces on the sides of the chimney in the two front chambers, while in this house, because of the chimney location, they are on the front.
