No 1 Ty Mawr

No 1 Ty Mawr is a house that has been divided into two residences. It is constructed of whitewashed rubble stone and features a slate roof with stone chimneys. The building has two storeys. The northern end of No 2 has a large external chimney breast with a stone stack, while No 1 has a smaller stone ridge stack at its original gable end, both equipped with dripstones. There is a rear wing with a stone ridge stack for No 2.

On the first floor, there are four windows with thin slate sills: No 1 has two pairs of casement windows, and No 2 has two 9-pane sash windows, with the right one being a replacement. The ground floor of No 1 features a larger window to the left, which has a heavy oak lintel and a thick stone sill. Next to this is a door with a timber lintel, located close to the door of No 2, which has two small-paned paired casements to the right. The openings on the ground floor are generally not aligned with those above.

To the left of No 1, under the same roof, there is an added section that contains two altered windows with brick heads above earlier openings, positioned at mid-height due to the sloping site. The southern end wall is made of rubble stone. The northern end wall of No 2 features a large external chimney with a stepped chimney breast and a small window on each floor to the right. The rear wing has an outshut to the north, which includes two windows and a square rubble stone stack on the ridge. The end gable is whitewashed and has an upper window. The interior has not been inspected.
