The Warner House, also known as MacPheadris-Warner House is a historic house museum at 150 Daniel Street (corner of Chapel Street) in Portsmouth, New Hampshire, United States. Built 1718-23, it is the oldest brick house in Portsmouth, and is one of the finest early-Georgian brick houses in New England. It was declared a National Historic Landmark in 1960, and is listed on the National Register of Historic Places.
The Warner House is a 2-1/2 story brick structure, with walls 15 inches (38 cm) thick laid in Flemish bond. A belt course separates the two main floors, and the slightly overhanging cornice is studded with modillions. It now has a gambrel roof; this is a later modification to what was originally a pair of side gable pitches with a deep valley between them. At the break line in the gambrel there is a low balustrade, which was probably added at the same time as the house's cupola. The interior of the house follows a typical Georgian four-room plan, with an added kitchen wing in the rear. The walls of the central hall and stairway are decorated with murals.
The house was built by Archibald MacPheadris, who was succeeded in ownership by his son-in-law, Jonathan Warner. The house remained in the hands of Warner's descendants until 1930, being used as a summer residence by the extended family from the 1880s on. The house was threatened with demolition when an oil company offered to buy the property to erect a gas station. The Warner House Association was established in 1931 to prevent this fate, and now operates the property as a historic house museum. Although the association originally sought to interpret the property at its original Georgian height (c. 1762), it shows artifacts and styles from its earliest to its latest days of private ownership.
