Rosewastis Farmhouse

Rosewastis Farmhouse is a farmhouse dating to circa 1830, with minor later alterations. It is constructed of squared granite rubble with granite dressings to the front and right side, the remainder being of granite and slatestone rubble. The roof is slate, with lead rolls to the right, and has gable ends behind a parapet. Chimneys are present with ashlar shafts and cornices.

The farmhouse has a double-depth plan, with the entrance set off-centre to the right. The principal room is located to the front and rear right, with a stair hall to the rear leading from the entrance hall. Service rooms are positioned to the left, both front and rear. Externally, it appears as two storeys on a plinth, and the front elevation is asymmetrical with three main bays to the right and a single bay to the left. The central bay to the right features a round-arched doorway with a keystone, containing a recessed 20th-century glazed door with a Gothic fanlight. There are 12-pane sashes with cambered arches and keystones to the right and left of the doorway at ground level, with three matching sashes at the first floor. The bay to the left has similar sashes at both ground and first floor. The right side features sashes similarly spaced and detailed, and a shallow elliptical arched niche with a keystone centrally at the first floor. The left side of the building is largely blind, with a single-storey addition of the later 19th century containing a door and two casements. A rear range projects slightly. A half-glazed door leads to the cellar on the rear, and a large 28-pane sash with a round arch and Gothic glazing bars illuminates the stairwell on the upper level. The rear elevation is asymmetrical, with a half-glazed door under a segmental arch, 9-pane sashes with cambered arches to the right and left, and a smaller window with a cambered arch to the left. At the first floor, sashes with 12, 16, and 4 panes, each with cambered arches and keystones, are visible.

The interior was not fully inspected, but includes an open-well staircase with a swept handrail. The principal rooms on the ground floor have panelled window shutters. The house is likely to retain other features of the early 19th century, such as cornices and good carpentry details.
