Description
Fernside Mill is a former mill building that is now roofless and in extremely poor condition. This three-storey structure was built against the mill dam. The former top floor is level with the road and has direct access through the gable end. The other two floors were below the water level in the mill pond, creating a 5-meter head.
The building is made of coursed squared rock-faced local sandstone rubble. Although the roof is missing, the gable ends remain intact. The south-west gable end, facing the road, features an elliptically-headed boarded door and an inset Victorian wall post box. The elevation facing the mill pond (north-west) is single storey, but the former timber frame with vertical louvres is lost; this was a key feature of the mill, as the louvres ventilated the paper drying floor. The downstream (south-east) elevation is three storeys high and originally had two doors and three windows on the ground floor, along with five windows on the first floor. While the elliptical heads and openings are still visible, most of the windows are missing, and some ground floor openings are blocked. The upper floor has completely collapsed.
The original layout, which included a drying floor at the top, a paper-making floor in the middle, and a rag floor at the base, is no longer discernible due to internal collapse and the building's deteriorating state.
