Description
The Olde Telegraph is a single-storey telegraph station building, featuring a square accommodation and office block at the rear (south) and a rectangular block to the north with a semi-octagonal splayed end used as a lookout. There is now a single-storey addition along the east wall and a glazed conservatory or porch at the west angle. The building is solidly constructed with three layers of brick and rendered, topped with a modern slate roof.
The windows on each face of the semi-octagonal splayed end of the north block are large 16-pane hornless sashes, while other openings have modern doors and replacement casement windows. The north block includes a doorway in the west wall and a window in the east wall, while the accommodation block features two large windows on the west, south, and east walls, a smaller window offset to the north on the west wall, and a single central window on the north wall. A tablet on the west wall of the lookout block provides details and the date of the station's construction.
Originally, the accommodation and office block had four interconnecting rooms with a central stack for fireplaces in each room, and the lookout block contained a fireplace in the southwest corner. The interior of the station has been modernised but still retains original beams and tongue and grooved pitch pine ceilings, which are now encased.
