1/183 Engine house at 5V53783104

GV II

Beam engine house for 80 inch pumping engine. Circa 1880. Probably granite ashlar
bob wall (overgrown with ivy), otherwise granite rubble with granite and brick
dressings. Original iron tie rods through the length of each wall. Some remains of
scantle slate roof and boarded studwork over bob wall.
Plan: rectangular plan with thicker bob wall with narrow doorway (east) and large
boiler doorway in gable-ended wall (west). The engine moved to South Crofty in 1903
and still extant.
Exterior : Tall plinth; arched doorways to the front and rear walls and arched stair
window to each wing wall. (The bob wall arch is ordered). The other openings are
tall rectangular window openings (3 to each floor of the wing walls and 2 pairs of
openings to each floor over the boiler doorway) and a blind oculus with brick cross
to the gable end. Remains of original window frames.
Interior : original scissor-truss roof structure; pit towards the bob wall and round
dressed granite cylinder platform.
The engine formerly fitted to this engine house was built by Copperhouse Foundry,
Hayle, to a design by Samuel Grose. It was originally fitted to Wheal Alfred
Consols, then Crenver then lineal Abraham before being moved to Tregurtha Downs.
This engine house is similar in design to one never completed at Tregurtha Farm
nearby and to East Wheal Rose (lead mine).
