Stable, Clarendon House, 30 Manse Road, Linlithgow

Clarendon House is a large, classically styled villa dating from around 1820, with later alterations in the 19th century. A two-storey addition to the rear was built around 1875, and bay windows were added around 1845. The building is roughly L-shaped, and a modern two-storey addition to the east side is not included in the listing.

The villa is primarily constructed of squared and coursed cream sandstone rubble, with ashlar facing on the south elevation and to raised margins. Distinctive features include a base course, cills, eaves courses, a cornice, a blocking course, broad pilaster quoins, and architraves to the first-floor windows on the south elevation.

The south (entrance) elevation is symmetrical and three-bayed, with a slightly advanced central bay featuring a distyle in antis Greek Doric portico. This portico contains a gothic panelled door and a multi-pane fanlight. The sides of the portico are flanked by balustraded, architraved cast-iron windows. The first floor has regular fenestration.

The west elevation has four windows at ground level and three at first floor, arranged asymmetrically, with a three-storey Italianate tower addition to the left. Wallhead stacks are present. The eastern elevation is also asymmetrical, and abuts a later two-storey addition. A service courtyard sits between the main villa and the later additions to the north rear.

The rear additions include a four-stage "tower" with angle and eaves markings, featuring two windows at cill course level on each face at the upper storey. It has a piended lead roof with a decorated weathervane. A piended block sits to the left, displaying symmetrical two-bay design with regular fenestration and a wallhead stack. The north rear elevation is symmetrical with two bays, presenting a two-storey canted bay on the right and bipartite windows on the left at both ground and first floor levels. The east side elevation of the rear addition features a wallhead stack.

The interior of the villa includes decorative encaustic tiles in the porch, a tripartite pilastered and half-glazed vestibule door, and a stained-glass panel above the door. Other interior features include fine plaster ceilings and friezes, marble fireplaces, doors with moulded architraves and bracketed cornices in the drawing-room, and a dog-leg staircase with timber balusters. A stained-glass stair hall window features a monogram "JMR." The windows are a mix of four-pane and plate glass sash and case styles. The roof is of grey slate, with sandstone stacks.

The stables, likely dating from around 1875, are a single-storey and attic building with a symmetrical three-bay rectangular plan. They are constructed from cream bull-faced snecked sandstone with picked and droved ashlar dressings, overhanging eaves, and chamfered window surrounds. The north elevation is symmetrical, featuring three windows and a central hayloft door (now a window) to the attic, flanked by rooflights. A door is located on the right return, and the south elevation has three narrow windows. The interior of the stables retains a cobbled floor, boarded walls and ceiling, and half-tiled walls. These windows incorporate six-pane upper sashes and plate glass lower sashes, with a green slate roof.

A squared and coursed sandstone wall extends west, enclosing a courtyard. Gatepiers and a boundary wall are constructed of ashlar coped rubble walls with corniced rusticated ashlar piers topped with fluted pyramidal caps.
