Description
Tan-y-Bryn is a terrace of three 2-storey cottages located in Llandygai. The cottages were built as a group of three and comprise a central range with projecting gabled wings, each wing forming a separate cottage. The walls are constructed of snecked slate-stone blocks with slate hanging on the first floor, and the roof is slate-covered with deep verges. The central range features a slightly offset gabled stone and timber porch containing a 20th-century half-glazed door, alongside a 3-light mullioned and transomed timber window. A 3-light flat-roofed dormer with a pediment in the centre has been fitted with late 20th-century plastic windows. Each gable has a 24-paned 4-light window on the first floor, alongside a 3-light mullioned and transomed window and a smaller window on the ground floor. Gabled porches are present on each return. The porch on the left has a boarded door in the front wall, while the porch on the right is open to the front with a boarded door only on the side wall of the cottage, which is likely the original arrangement. Prominent ridge stacks are located to the left and right of the central range, featuring stone bases and clustered brick diagonal shafts with moulded capping. The interior of the cottages was not inspected at the time of survey.
