Leigh and Glanllyn

Leigh and Glanllyn is a one-and-a-half storey building with a basement, designed symmetrically around a central entrance. It features a main range flanked by cross-wings, with a lean-to structure running between the wings at the rear basement level. The building is constructed of brick with rock-faced stone dressings, sitting on a basement made of snecked, rock-faced Cefn stone. The roof is slate, with coped gables on moulded kneelers and added skylights. There are axial stacks on the left and right sides of the main range, along with two lateral stacks on each cross-wing, which were added in 1931.

The front of the main range has a central, buttressed cross-gable that contains a tall round-headed doorway with a prominent key. Above this doorway is a blank shield in relief. On either side of the cross-gable, there are half-lit doors with overlights beneath stone lintels. The cross-wings are believed to have had large openings that were blocked when the building was converted into dwellings. Each cross-wing features a blank shield in relief above a 3-light casement window under a segmental head, which was inserted through a shaped gable that is now roughcast. There is also a canted bay window with small-pane glazing that was added in 1931. The side walls of the cross-wings have two 12-pane sash windows and two flat-roof dormers, both added in 1931, along with 20th-century additions to the right cross-wing. At the rear, the cross-wings have sash windows under segmental heads on the ground floor and in the attic, as well as a boarded-up 3-light mullioned window under a stone lintel in the basement.

The lean-to structure is made of a purple-coloured brick that is distinct from the red brick of the main building. It has a shallow cross-gable at the center, featuring a tall round-headed window with stone imposts and a key. This window is partially boarded up, with some glazing bars visible behind it. On either side of the lean-to, there are two windows under lintels that are now boarded up.

The building was not inspected in November 1996.
