Description

No. 1 Glyndu is part of a group of four similar but not quite identical cottages in a terrace, built from irregularly coursed slate masonry and topped with slate roofs. The designs of the cottages are alternately handed, with the left pair being slightly larger. Each pair features doors at the center and chimneys on the outside. They have four-panel doors with rectangular overlights and gabled canopies supported by timber brackets.

The left pair of cottages includes mullion and transom windows, with the left cottage still retaining these features. The windows below are tripartite, set on stone sills with plain stone lintels, while above are approximately square oriel windows on brackets, topped with metal roofs.

The right pair of cottages has tripartite sash windows below, also with stone sills and plain lintels, and approximately square four-pane sash windows above, again with stone sills and plain lintels.

No. 1 is the outer cottage of the smaller pair, located to the right of the terrace.
