Bryn Mawr Farmhouse

Bryn Mawr Farmhouse is a two-storey building with a cellar, featuring three windows on the front. It is constructed from coursed rubble masonry and has a moderately pitched slate roof with a cavetto eaves cornice and plain verges. The house has tall rectangular stone stacks with water tabling. The attic includes a pediment with a blocked oculus, which once held a clock in the 19th century. The first-floor windows have shallow upper sashes with nine panes and stone lintels, while the ground floor has similar windows. The central doorway features a stone lintel and a part-glazed door.

On the northern gable end, there is a 12-pane sash window on the first floor, similar to a 12-pane window on the ground floor to the left. The rear elevation has a nine-pane sash window on the ground floor to the left, which was formerly a doorway, and a 12-pane window in the center. There is a mid-18th century rubble lean-to outshot on the right with a slate roof. Features on the northern side include a loft window above a ground floor window, stone lintels, and a modern framed doorway to the right with a stone lintel and a plank door. The southern gable end has a window/door on the first floor that leads to a higher external ground level.

To the west of the house, there are substantial remains of an early terraced garden, which includes later burials. Inside, the farmhouse has stop-chamfered transverse ceiling beams and contemporary joists. There is a deep timber bressumer with broach stops to the chamfer, and a spiral stairwell to the right, although the stairs have collapsed. A modern plank and muntin partition divides the space. The first floor also features stop-chamfered ceiling beams. The roof consists of four bays with two original 17th century trusses. The trusses are through purlin collar and tie beam types with crossed decorative upper struts. An inscription in Welsh at the foot of the front principal of the center truss reads: "Y TU HWN YN Y FLWYT 1617 REES LEWIS AI GWNAETH". The truss over the northern end dates from a circa 1800 rebuild and is a cruder tie beam truss with lower angle struts. The original purlins are turned on edge to raise the roof. There is a cambered bressumer in the 18th century lean-to, which includes a bread oven on the left and a half-truss for a heated loft.
