Tan-y-Coed

Tan-y-Coed is a 2-storey building with a symmetrical front featuring three windows, constructed from coursed rubble and dating from the 19th century. It has a slate roof and rendered end chimney stacks. The small pane sash windows are 16-pane, except for the one above the porch, which has a parapet and cornice. The entrance is segmental with a 6-panel door, while a modern inner door is present. Inside the porch, there are two slate tablets that describe the building's history, noting that it was positioned to be clearly visible from Anglesey.

At each end of the building, there are single-storey screen walls with boarded doors set in round-arched entrances, providing access to the cross ranges. The left gable end features French windows, while the right end has a scribed rendered finish. A slate-paved courtyard is located at the rear, with cross ranges extending back to Castle Bank. The left range retains small pane sash windows, including one that slides horizontally, and features a large pebbledash chimney stack that may indicate the former extent of this range before it was enlarged. The right range includes a Victorian larder with slate shelving.

The front of the property is marked by dressed stone gate piers, slate steps, and plain iron railings.

Inside, the building retains original features such as 6-panel doors, a segmental arch in the hallway, and a tightly winding staircase with a turned newel. The first floor was originally undivided and served as a hospital ward.
