Description

House, dating to the late 16th and early 17th centuries, with alterations in the 17th century and restoration in the 20th century. The building is constructed of rendered, colour-washed cob with a slate roof and rendered chimneys. Originally a three-room plan with a cross passage, the house now features a lateral stack to the hall and a projecting stack to the left gable end. A stone stair is located adjacent to the hall stack, while a rear projection, lit by a two-light, ovolo-moulded mullioned window, contains a second stair. There is a partial rear outshut. The right end of the front likely represents a former unheated parlour, characterised by a lower roofline. Steps lead up to a two-storey, gabled porch with seating. The second storey of the porch was rebuilt in the 1970s and includes a two-light granite mullioned window replacing an earlier design. The ground floor front features a three-light casement with glazing bars on the left, a granite-framed stair light to the right of the porch, and a four-light granite mullioned window with eight panes per light to the hall. A ground floor three-light casement with glazing bars is located on the right. The first floor has a three-light casement with glazing bars on the left, a porch window, a granite-framed stair light, and two two-light casements in 1970s gable dormers which originally had windows under raking roofs.

The interior ground floor is slate-floored, with stud partition walls defining the cross passage. The hall fireplace has granite lintels and jambs, alongside a slatestone newel stair to the right of the hearth. The left-hand ground floor room contains an unhewn fireplace beam, while the right-hand ground floor room has widely-spaced ceiling beams and a low, semi-circular projection to the wall facing the hall. The first floor reveals three bays of raised crucks above the hall, featuring a threaded ridge and collars mortised into the principals. The room to the right of the hall has a fireplace and a curved principal with a low face and side-pegged joint. There is evidence of a former bressumer in the room above the present hall. Other principals throughout exhibit curved feet. A first-floor stud wall incorporates moulded timbers from a demolished house in Week St Mary. A fireplace with a stone lintel is found in the first-floor room to the left. The hall fireplace lintel originally featured decorative plasterwork depicting moons, stars, and heads; one head remains in the possession of the current owner. Group value context is that this is a building of significant historical and architectural merit.
