Description

Roscadden Farmhouse is a farmhouse dating from around the mid-17th century, with a parlour wing that is part of a 16th-century house that was rebuilt in the 20th century. The building features painted rubble and cob walls, slate sills, and wooden lintels. It has an asbestos slate roof, with the eaves raised in the 20th century and an external stone rubble stack at the left-hand gable end. The farmhouse has an L-shaped plan, with the parlour on the left, a best chamber or solar above it, a stairwell on the right, and a vestibule between the parlour and stair. There is a wide shallow room behind the stair, likely originally a buttery, and a 20th-century wing at right angles to the front right, built on the site of the original 16th-century house, which is set into the bank at the rear.

The farmhouse is two storeys high and has a one-window front facing north-north-east, with the parlour on the left and the projecting gable end of the 20th-century wing on the right, which features a 20th-century quadrant porch in the angle. The original 17th-century oak mullioned windows remain on the ground and first floors, with the ground floor window being a two-light version of what was originally a four-light window, now featuring a 20th-century glazed door replacing the right-hand lights. The solar above has a three-light window. The ground floor window has ogee internal mouldings, while the first-floor window has bowtell moulding. There are also 20th-century casements with glazing bars and a 20th-century double top-glazed door to the porch.

Inside, the parlour wing is largely intact and has seen little alteration since the 17th century. It features deep ovolo-moulded cross beams with ogee tongue stops in the parlour, a wide dog-leg stair with a late 18th-century balustrade featuring rectangular balusters, and a fine plaster barrel ceiling in the chamber above the parlour, complete with moulded cornices. The feet of the trusses are exposed under an inner eaves soffit, with the lower cornice carried around them to resemble brackets. The original roof structure has not been inspected. Roscadden Farmhouse has some historical documentation, including a mention of John Roscadden in 1594 and references from 1663 and 1679 in the Buller papers. The farmhouse features rare surviving 17th-century wooden windows and a particularly rare plaster ceiling, along with the ovolo-moulded beams, which would have been common in the 17th century.
