Description
Pandy Bach is a two-storey house built into the hillside, oriented roughly northeast to southwest, with the main facade facing northwest. There is an outshot at the rear (southeast) and a single-storey cowhouse to the left (southwest). The house is constructed from mortared rubble masonry, featuring large stones as quoins and lintels, with boulders at the base of the walls. It has a slate roof topped with tall square stone gable stacks that have dripstones and capping. The house has a two-window layout with a doorway offset to the right (southwest). The windows are two-light casements, and the first-floor windows at the front and rear are set in gabled half dormers that extend above the eaves. At the rear, the roof continues over the outshot, which has a boarded door located in the angle.
The cowhouse features a boarded door on the left (northeast) side of the front (northwest) elevation and a pitching hole in the southwest gable.
Inside, the house has 19th-century partitions that divide it into two rooms, and the fireplace has been blocked off. However, it retains the stone spiral staircase leading to the fireplace in the southern corner.
