Description

Glanaber is a three-storey house built in the 18th century, forming a pair with Llwyn Onn. The houses present a slightly irregular five-window facade. The exterior is white-painted Flemish bond brickwork, with window and sill details in rubbed brick and stone, respectively. The top floor features eight-pane horizontally sliding sash windows, while the first and ground floors have sixteen-pane hornless sash windows. Each house has a door sheltered by a slate-roofed porch and canopy.

The brickwork of Glanaber appears less weathered and more regular than that of Llwyn Onn, indicating it may have been built later to emulate the style of its neighbour. Glanaber is narrower than Llwyn Onn and lacks a dentil cornice. The interior is currently unexamined.
