Description

Fridd-isaf is a farmhouse that features an earliest range which now serves as the rear wing, positioned at right angles to a front range built around 1800. The front range is two stories high with three windows and constructed from roughly coursed rubblestone, which was formerly limewashed, and has a boulder plinth at the earlier part. The roofs are slate-covered. The front displays late 20th-century horned glazing bar sash windows with slate cills and a central plank door, along with rebuilt integral end stacks. On the right gable end, there is a small sash window with a slate cill and a projecting stone lintel on the ground floor. The lower rear range features an integral end stack with slate drips and late 20th-century raking eaves dormers on both sides, with the south dormer extending down to create a catslide outshut that once housed a mill. Adjacent to it is a wheel-pit that retains a 19th-century iron wheel equipped with late 20th-century paddles.

The building underwent significant alterations in the late 20th century, particularly in the rear range. The front range includes a 19th-century quarry tile floor in the left ground-floor room and a formerly open fireplace with a slate lintel and a gun/spit rack above. There is a 19th-century straight-flight staircase in the central hallway, with timber partitions on both floors and plank doors throughout. The rear range has a massive end fireplace featuring slate-stone voussoirs supporting a wide segmental arch, along with a partly reconstructed bread oven. The original heavy cross-beam and repositioned joists are present, and a reconstructed plank and muntin screen, of which only the head-beam is original, indicates the position of a probable former cross-passage that ran parallel to the back wall of the 19th-century part of the house. This screen may have originally supported a loft, while the remainder of the 17th-century range is now continuous to the first floor. The roof structure consists of three bays with two massive A-frame trusses.
