Buckingham House

Buckingham House, formerly known as The Spotted Dog, is located on High Street in Portsmouth. This building dates from the 16th or early 17th century and was originally a timber-framed house. It underwent alterations and was refronted in the late 17th or early 18th century, later being rendered. The house has plain tile roofs, with No.10 1/2 featuring a brick stack on the right.

No.10 1/2 is a two-storey and attic structure with 2 1/2 bays. It has a projecting half bay on the left, which includes a recessed six-panel door (two flush, two fielded, and two glazed) set in a moulded architrave, while the first floor is blind. To the right, there is a 16-pane sash window below a rusticated round arch, which is flanked by a pilaster separating two round-arched first-floor sashes with glazing bars and similarly styled arches. The building features a coped parapet and two flat-roofed dormers.

No.11 is a two and three-storey building with two bays. It has a two-storey bay on the left with a door similar to that of No.10 1/2, but supported by heavy carved brackets under a cornice. The first floor is blind, and there are two sashes on each floor of the right-hand bays. The ground and first floors have 12-pane sashes with bracketed cornices above, while the second floor has windows with nine unequally-hung panes. A sill band is present on the first floor, and there is an eaves cornice below the parapet on the right bays.

Inside, the building features panelling and partly exposed timber framing. A plaque on the wall notes that George Villiers, Duke of Buckingham, was assassinated here by John Felton on 23 August 1628.
