Description
Ty Llangenny is a two-storey house with an attic, dating from the 18th century. An 18th-century wing was built into a bank as a lean-to against the main house, projecting forward on the left under a gabled roof. Later lean-tos were added to the right gable end and behind to the left. The house is constructed of rubble sandstone with a slate roof. The main elevations are roughcast and painted white, as are the rear walls. White brick stacks are located on both the right and left sides of the main house, and a similar stack is present at the end of the wing.
The two-window front of the main house features 12-pane hornless sash windows in the upper storey. An inserted casement window is located to the right, and an inserted half-lit door is on the left. A boarded door with a three-pane overlight is situated at the right end. A 19th-century attic casement has been inserted into the right gable end, above a lean-to. The wing’s side wall, facing the front, has a boarded door to the right, and three-light casement windows inserted in the 19th century in each storey, beneath timber lintels and with stone sills. The rear wall of the wing contains a boarded door under a timber lintel on the ground storey, an inserted casement above, and a small opening to the attic malting floor. The integral stair turret, behind the right side of the main house, is full height and contains a three-light mullioned window in the gable end. A blocked attic window is also present. Lean-tos behind the main house and a single-storey projection behind the stair turret date from the 19th century and contain later inserted windows.
The main hall contains re-set wood panelling and a stone fireplace. A staircase leads to the first floor and continues to the attic, featuring oak treads. Upstairs, the main house has two three-light sunk-chamfered mullioned windows to the rear, which are not visible from the exterior. The roof structure consists of trusses with lap-jointed collars. The wing has a flagstone and cobbled floor with integral drains. In the attic of the wing is a plastered malting floor, and the trusses are supported by tenoned collars.
