Siambr-wen

A two-storey, two-window farmhouse facing east, with a long central rear wing also of two storeys but with a slightly lower roof eaves. The house is in white-painted quasi-rubble with slate roofs. The front range has a hipped roof with large stone chimneys at each end. The rear wing has a gabled roof with no surviving chimney. Small single storey annexe in the south-west angle between the main range and the wing, at former fireplace position.

At front (east) the house has flush-framed small-pane mullion and transom casement windows in segmentally arched openings below, and smaller similar mullion windows above against the eaves. Modern porch at centre. At the rear of the main range is a similar upper window south of the rear wing, and a small window to the ground storey north of the rear wing. Moderate eaves projection all round; large chimney stacks in similar white painted stonework

The rear wing has windows and door to the north elevation but its rear elevation to the south is blind. In the north elevation are three ground storey windows in segmentally arched openings and a door within a modern porch, and two upper windows probably in altered openings.

Siambr-wen retains a large fireplace at each end of the main range, and a lateral fireplace in the south side of the rear wing.
