Plas-yn-llan

The core of Plas-yn-llan is a 2-storey timber-framed house, slate roofed, ranging east/west. The east gable is of uncoursed stone and carries a large square chimney stack. The framing of each storey at west is 2 panels high, massively decorated with diagonal timbers forming lozenges and herringbone patterns; most of the north elevation is similar except that the whole 2-storeys consist of only 3 panels in height. The south and west elevations are considerably jettied at first floor. The west gable end is also slightly jettied at roof level. The corner post carrying the angle of the jetty (at south-west) carries three brackets beneath each of which there appears to be a thin pilaster carved from the solid. At west there is a mullioned 3-light window above and a 4-light mullion and transom window below, and at north there are three 3-light windows above and below. A very large later rendered stone chimney stands against the jettied south elevation. This has a slated west extension, perhaps for an original oven. There is another offset above eaves level, a short section of bare stonework at the top, and 2 diagonally-placed square shafts.

Later additions are a slate-roofed brickwork lean-to against the east gable wall and two 2-storey brickwork wings extending south, plus a modern glazed conservatory. The shorter wing has modern Tudor-style semi-glazed doors.

Interior features (not inspected) are said to include a timber screen, wattle and daub panels, a gardrobe off the principal bedroom, and a staircase with close string and splat balusters.
