Clarendon House, Clarendon Park

Clarendon House is a large house, likely built between 1717 and 1737 for Benjamin and later, Peter Bathurst, a Member of Parliament for Salisbury, who died in 1748. It was remodelled internally in 1814 and again in 1920. The facades are of Chilmark ashlar limestone, with rendered brick to the west side where a 19th-century wing was removed. The roofs are hidden behind a hipped slate and lead covering.

The house is two storeys high with a basement. The plan features a large central stair hall on the north side, with principal state rooms located in each corner of the rectangular layout, the centre third of each front projecting forward, particularly on the south side. The south front is deeply recessed and now contains a single-storey ballroom from 1920. The north front is in the style of Thomas Archer and has two storeys over a semi-basement, with nine window bays. The central three bays project forward and are quoined, topped with a segmental open pediment containing a recessed blind lunette. The door surround has channel rustication, a Venetian-style arched head, and an enlarged dropped keystone, with four triglyphs and a flat pediment above. The piano nobile features 12-paned sash windows, without keyblocks, and aprons beneath the sills. An intermittent balustraded parapet runs along the top. Originally, the south elevation had two projecting wings with a recessed centre; each wing had three windows within raised stone architraves and aprons. The ground floor of the centre section features French windows. Corner details include cornices and raised stone quoins. A Venetian stair window was added in 1814, and a differently detailed Venetian window was incorporated into the ballroom in 1920.

The east elevation has seven bays, with the centre broken forward and quoined, and topped with a triangular pediment. A slender central doorcase supports an open pediment above.

The interior was completely remodelled in 1814 and 1920. The 1814 stairhall contains a Perron staircase with an iron handrail and bracketed treads, a black and white chequer floor, and black marble Ionic columns on either side. The staterooms have plaster decoration in the 18th-century style from 1920. The northwest room and the central east room have late 18th-century-style Adam fireplaces with marble slips. The upper-floor rooms are plain. An original early 18th-century staircase with a closed string leads to the cellar. The cellars are brick-vaulted, with one section of beamed construction that may be a remnant of a previous house on the site.
