Ty Glas Farmhouse including attached Byre

Ty Glas Farmhouse, which includes an attached byre, is a one-and-a-half storey building constructed of rubble with an old slate roof. It features end chimneys with plain capping and weathercoursing, and a rubble gable parapet on the left side. The entrance is off-centre and has a modern part-glazed door. To the left, there is a blocked stair-light with a lime-render skim, and to the right and far left, there are 4-pane 19th-century casement windows. Above, there are two contemporary gabled rubble dormers with later windows that break the eaves, one of which on the right is modern. The rear has small 4-pane windows and one larger 6-pane casement on the left, along with a modern part-glazed porch on the right and a modern window beyond. There is also a rubble dormer with a hipped roof and later flanking gabled dormers, which are now rendered and have modern windows.

To the left of the house, there is a late 18th or 19th-century two-bay cart-shed with a large plain opening to the gable and a timber lintel. To the right, there is a rubble byre addition, likely from the 18th century, which has a corrugated iron roof over original three-bay pegged collar trusses. This byre has a loading bay on the right gable end and two stable doors at the rear with exposed timber lintels. At the rear of the house, forming the lower arm of a T, there is another byre addition, probably from the late 18th century, built of rubble with an old slate roof. This section has entrances with boarded doors on both the house and byre sides, the latter featuring a 19th-century stopped-chamfered doorcase, and a 2-pane window with ventilation slats beneath on the right. Adjoining the gable end of this byre section is a later extension made of corrugated iron and rubble.

The interior of the farmhouse was not accessible during the inspection in January 1995, but it is known to retain a beamed ceiling and a fireplace with a chamfered bressummer in the former hall. It is also said to have a stone newel stair next to the fireplace.
