Adderbury House

Adderbury House is a large house, originally incorporating parts of a mansion, and now serving as an old people's home. The core of the building dates to the 17th century and was remodelled around 1722 for the Duke of Argyll. It was enlarged in 1731 by Roger Morris and altered in 1768, probably by Sir William Chambers, for the Duke of Buccleuch. The original structure was largely demolished in 1808, and the house was remodelled and enlarged again in 1891 for J.W. Larnach.

The house is constructed of Marlstone ashlar with Stonesfield-slate roofs and ashlar stacks, arranged around a courtyard plan and in a Baroque style. The south front, now the main entrance, has three storeys and six windows. It features a plinth, a second-floor storey band, and a plain parapet that projects forward in the two central bays below a triangular pediment containing a blind oculus. The sash windows have semi-circular heads on the ground and first floors, and segmental heads on the second floor. A late-19th century stone portico with four Ionic columns and a heavy entablature shelters the central doorway and two flanking windows. Rainwater heads made of lead, dated 1722, are located in the outer bays, taking the form of triangular consoles with scrolled lugs. Plainer lead rainwater heads dated 1750 are on the return walls, and one on the west wall bears the Argyll crest and a date, now partially obscured. Later 19th-century east and west ranges, also with six windows, are set back but project a bay on either side of the main range; both have parapets that break into central pediments. The east range seemingly incorporates walling from the earlier building. A single-storey kitchen range stands on a plinth, which contains the cellars of the early-18th century north range, originally part of a three-sided courtyard. Remaining sections of early walling are present on the inner faces of the north and south ranges. All ranges have hipped roofs.

The interior of the south range retains some 18th-century egg-and-dart architraves, a Rococo plaster ceiling in a first-floor room, several small 18th-century fireplaces, and the upper flights of a late-18th-century staircase with stick balusters and a mahogany handrail. The cellars below the north wing feature depressed-arched stone vaults springing from square imposts, spanning three bays wide by at least seven bays long.
