Description
The Sanctuary is a house, likely dating to the 18th century, with later alterations and extensions. It is constructed of painted roughcast and stucco, with 20th-century concrete tiles to the roofs and brick chimneys at the left end and on the ridge (originally the right end). The house is two storeys and has an attic, originally comprising four bays, with a matching extension to the right. The windows are set low, with plain walling above, rising to a renewed brick parapet. There are two small hipped dormers, and the windows are 12-pane horned sashes within thin stuccoed surrounds. A sill course runs beneath the first-floor windows, with roughcast above and stucco below. A 20th-century door is set within a pedimented timber doorcase in the second bay (originally the centre bay). A lean-to addition is present to the left end, along with a plate glass sash window between the first floor and attic levels. A single-storey lean-to range extends to the rear, featuring a brick ridge stack, a window, a door, and a recessed section with a roof supported by 19th-century curved brackets, and two 12-pane sashes within. The rear of the house is reported to have a two-storey lean-to and exposed rubble masonry, with openings and blocked openings of various periods.
In 1997, the interior included an entrance hall and staircase with stick balusters. A wall to the right opened into a sitting room with early 19th-century ceiling decoration, featuring a central rose, ribs, and an enriched cornice. Front and rear windows were fitted with panelling, shutters and moulded surrounds. A marble fireplace was present, along with two elliptical arched recesses with moulded surrounds. A former dining room to the left of the hall had a rear doorway flanked by elliptical-arched recesses within moulded surrounds. Behind the dining room, an axial corridor led down to a cellar. The first-floor landing featured balusters, and fielded panelled doors led to the bedrooms. An axial corridor with wide floorboards gave access to the attic, where pegged roof trusses were found. The rear cross range had stop-chamfered spine beams with run-out stops.
