Description

No 2 Ty Mawr is a house that has been divided into two separate dwellings. It is constructed of whitewashed rubble stone and features a slate roof with stone chimneys. The building is two storeys tall. On the northern end of No 2, there is 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 also a rear wing on No 2 that has a stone ridge stack.

The first floor has four windows with thin slate sills; No 1 has two pairs of casement windows, while No 2 has two 9-pane sash windows, with the right one having been renewed. On the ground floor, No 1 features a larger window to the left, which has a heavy oak lintel and a thick stone sill, followed by a door to No 1 with a timber lintel, located close to the door of No 2. The door to No 2 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, there is an added section under the same roof that has two altered windows with brick heads from earlier openings above. These are set at mid-height relative to the rest of the building due to the sloping site. The southern end wall is made of rubble, while 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 with two windows and a square rubble stone stack on the ridge, along with a whitewashed end gable that has an upper window.

Inside, the front room on the right has two heavy beams. There is a narrow dog-leg early 19th-century staircase off the passage to the left. The rear room contains an axial beam that connects to one parallel to the rear of the front range, positioned over a fireplace that has a massive timber lintel.
