Trefan

Trefan is a Grade II listed house featuring a prominent main block that stands three storeys tall and has five window bays, facing east. There is a two-storey rear wing that looks out onto the gardens to the south, and a one-storey and loft northern range that extends north from the rear wing, which is likely part of an earlier house on the site. The main facade is rendered and topped with a slate roof that has deep boxed eaves and two asymmetrically placed chimney stacks.

The entrance consists of a round-headed pair of partly glazed doors situated beneath a wide open pedimented porch supported by Tuscan columns. Above the doors is a fanlight adorned with intersecting Gothic glazing bars. The house features sash windows across all three floors, with 15 panes on the ground floor, 12 panes on the first floor, and 9 panes on the second floor. There is also a canted single-storey bay window with a flat roof on the south gable end that faces the garden. The rear wing has three bays, with its two storeys rising to three as the ground slopes down to the west, and it includes a central door leading to the garden. The northern wing has been partially rebuilt following an earthquake in the 1970s.

Although not inspected at the time, previous descriptions and the Royal Commission on the Ancient and Historical Monuments of Wales indicate that the interior includes a columned hall, a stair hall featuring an open-string staircase with a continuous handrail, and a roof lantern above. There are also some marble fireplaces present.
