Description
Ty'n Llan is a two-storey detached house built in the mid-19th century, featuring a T-plan layout. The building is constructed of rubble stonework, partially rendered, and has a slate roof. The short cross-wing facing south has two evenly placed windows on each floor. The upper windows rise into dormers with pointed heads and intersecting glazing bars, while the lower windows are sashes with glazing bars. There is a central doorway with an overlight and a modern door. The steep slate roof has unmatching end chimneys.
The longer range of the house has three unevenly spaced raised dormers on the west side, with pointed arches formed by two courses of yellow brick that match those on the south side. Below these dormers, from north to south, there is a modern garage opening (formerly the stables), a two-light modern sash window under a rough slate lintel (formerly the coach door), a small sash window with glazing bars, a larger sash window with glazing bars, and the main entrance doorway. The steep slate roof features two ridge chimneys. At the rear, there is an added lean-to dairy on the east side of the longer range, which is one storey and built of rubble, largely below ground level.
Inside, the ground-floor room towards the south end of the range adjoining the cross wing has an open hearth with a timber lintel and ceiling beams. The cross wing contains the parlour and the 'cegin orae'.
