2 Mill Street

Nos 1-4 Mill Street is a terrace of four estate cottages built in the third quarter of the 19th century, specifically designed as one-and-a-half storey homes for Lord Penrhyn after he acquired the estate in 1856. The cottages are constructed from rubble with shallow-pointed slatestone lintels above the ground floor openings. They feature a continuous slate roof with a tiled ridge and deep verges. There are two chimneys, shared between nos 1 and 2 and nos 3 and 4, each consisting of a two-stage design with a rendered lower section and a stone upper section, finished with plain cornice bands.

The cottages are arranged as one-window reflected pairs, with nos 1 and 4 having outer entrances and nos 2 and 3, the central units, featuring inner entrances. The doors are half-glazed and date from the 20th century, while the ground floor windows are 6-pane sashes with projecting cills, dating from the 19th century. The upper windows are also 6-pane sashes, set within mid-20th century flat leaded dormers that break the eaves. At the rear, each unit has a modern door and window combination, along with paired modern dormer windows on the upper floor.
