Powerhouse, office and substation at Skelton Park disused iron mine

The powerhouse at Skelton Park, built around 1876 for Bell Brothers' iron mine, is a single-storey building with a basement, constructed into the hillside so that the basement is at ground level on the north-west side. It features red brick in English bond with rock-faced and margined sandstone quoins and dressings, topped with a red, corrugated tile roof and timber bargeboards adorned with decorative finials and pendants.

The exterior is gabled, with a round-arched entrance consisting of double doors at the centre of the north-eastern gable end. The south-western gable end has three tall, round-arched windows, while each side elevation has six evenly spaced round-arched windows, which were formerly fitted with sliding sashes. All window and door openings have stone cills and arches. The unlit basement has a single doorway next to ironwork remains of equipment on the north-western wall. Additionally, there are three round openings for large diameter pipes, formed with fire brick headers.

Inside, the building comprises a single room above the basement, primarily occupied by substantial brick piers that serve as engine-beds.

Attached to the south-western gable of the powerhouse is the Time Office, a single-storey building with a hipped roof that is now missing most of its roof covering. It has double entrance doors and a window on the south-west side, while the north-east side, facing the pit yard, is mostly made up of windows, except for a doorway leading to a separate room on the north side, which is believed to have been a garage for a horse-drawn ambulance.

Across the road to the east of the powerhouse is the electricity substation, a two-storey brick building with a flat concrete roof topped by two brick-built ventilators. The tall ground floor is divided into two chambers for transformers, and the upper room, which was accessed via an external staircase, was designated for switch-gear.
