Description

Crugiau is a small country house dating from the mid-18th century, with alterations made in the early 19th century. The house is constructed of rubble stone with a gabled slate roof, featuring wide eaves and paired brackets of an early 19th-century style, as well as stone end stacks. The original diamond pattern of slate on the roof has been lost. The front has two storeys and four windows, with mainly 12-pane sashes that have cambered heads, stone voussoirs, and slate sills. There is wider spacing between the first and second bays, with evidence of rebuilding in the stonework in these areas. A wider window opening on the ground floor left contains a 16-pane sash. The doorway in the second bay is set within an early 19th-century doorcase, featuring a four-panelled timber door, long, narrow side-lights, flanking panelled pilasters, console brackets, and a plain cornice. The line of earlier eaves is still visible.

A first-floor sash window with horns is visible on the right end wall, facing south. The left end wall has a similar ground floor window and marks of the original lower gable line and chimney. A rear wing has been added to the left side, with 12-pane sashes on each floor. The main rear wall is of colourwashed rubble, and the rear wing to the right contains sash and pivot windows, paired horned sashes to the kitchen, a boarded door, and a rubble end stack. The rear was built onto a bedrock base.

The interior retains substantial original detail from both the mid-18th and early 19th centuries. A broad, low hall has applied early 19th-century detail layered over earlier 18th-century elements. This includes four arches to the rear wall, with reeded pillars and dentil cornices, facing the entrance, which is flanked by similar pilasters. The ceiling is three bays wide, with plastered beams and reeded soffits. The outer arches of the rear wall are semicircular, with a door to the left-hand rear wing and a cupboard door to the right. Two elliptical arches are in the centre; the left one is blank, while the right one opens onto a short staircase. This staircase is enclosed and branches at right angles on each side, featuring turned newels, stick balusters, and a swept-up handrail. An elliptical-arched early 19th-century sideboard recess is located on the back wall of the room to the right, with a dado rail and cornice. Arched recesses are found each side of the south end fireplace, with lozenge glazing bars to cupboard doors. Two plastered beams have ‘beads’ to the edge moulding. Panelled reveals define deep window splays. A left-hand room has mid-18th-century fielded panelling with a dado rail, and an early 19th-century alcove with reeded pilasters on the rear wall. A moulded timber fireplace surround, possibly from the early 19th century, has an early 19th-century iron grate. Two arched shelves are incorporated into the walls.

The roof consists of six bays overall, with four bays in the rear wing. The main roof has A-frame trusses, and the rear wing has trusses without collars. Purlins are lapped.
