Plas-yn-rhos Old Farmhouse

The house consists of a main range and 2 cross-wings plus a small west wing parallel to the main range, all roughcast and with slate roofs. The gables and larger dormers have plain bargeboards, the smaller dormers at west are hipped. There is a large axial chimney to the west of the main range and 3 other chimneys, all roughcast. Modern glazed conservatory at west, tall metal flue attached to adjacent chimney.

The main range has low eaves to front and to rear, both interrupted by 2-storey gables added in Arts and Crafts style. The north elevation features this addition including a first-storey 4-light leaded window over a parget panel. The parget panel has geometrical designs. To the right is the main entrance door, under a bracketted canopy; to the left a small modern window. The corresponding addition on the south elevation consists of 5 similar lights plus 2 in the flanks at first storey over a parget panel and a ground-storey mullion and transom window of 5 lights plus flanking lights. The parget panel on this side of the house has lozenges.

The east wing has two 9-pane sash windows, one 6-pane sash-window and a 2-light casement on the west side (facing the entrance). On the east side of this wing the fenestration is irregular. On the south gable (facing the garden) there is a 4-pane horizontally-sliding sash window. The ground-storey windows to east and south are leaded, with decorative features centrally. On the north gable there is a door only.

The west wing has four 12-pane sash windows on the west side, one now behind the conservatory. There is a single 12-pane unequal-sash window, a casement window, a small single light window and a door, irregularly placed, on the south gable of this wing.

The house is entered at the north side, a short north corridor connecting the wings and stairs. The north room of the east wing is inaccessible from the interior.

An important feature of the interior is the carved overmantel in the east wing, said to have come from Plas Ashpool, with initials DG and AG. Ogee stops on the beams of this later wing, C18 panelling.

There is an inscribed date (DG 1611) over the entrance but behind the present door, and another (1594) with a Welsh inscription in the west wing.

The house was under interior renovation when inspected.
