Description
Llethr is a house that features painted roughcast walls, a slate roof with close eaves, and stone stacks at both ends, with a larger square stack at the northern end. The building is one storey with a loft and has a double-fronted design. It includes painted brick voussoirs above two modern 4-pane casement windows and a central half-glazed door, all situated in their original openings. At the southern end, there is a modern addition that has one window on the front and one on the end wall. The rear outshut, raised in the 20th century, contains a casement window and a door.
Inside, the space has been converted into one room, featuring a large fireplace at the northern end with a timber lintel. There is a winding wooden staircase in the angle to the right, and the ceiling is joisted with wide floorboards.
