Description
Blaenglyn is a farmhouse constructed of painted rubble stone, featuring a slate roof that overhangs at the eaves and verges, along with stone stacks at each end. The building is two storeys high and has a three-window range of new 12-pane sash windows, with a centrally located part-glazed door. The lower openings have cambered heads, while the upper ones have been altered to include flat concrete lintels. There is an outshut at the rear.
The interior was not inspected, but in 1965, the layout was described as conventional, with a central passage hall and a room on each side. The main room to the west had a winding stair located in the corner by the fireplace.
