Left wall of the whim engine house - thumbnailThe pumping engine house measures approximately 9.2m by 7.3m and is approximately 7.9m high at the northwest corner and 9.2m at the northeast corner; it was built for a 70-inch pumping engine in 1826 and appears more-or-less identical to Taylor's engineRight wall of the whim engine house - thumbnail house to the west, built in the same year. The house has suffered similar damage to Taylor's, resulting in the almost total loss of the rear wall and great damage to the wing walls, mostly caused by failure of wooden lintels set into the walls. Much of the masonry is now held together by ivy although this is also causing damage to the structure.

 

Opening in left wall of the whim engine house - thumbnailThe whim engine house measures 9.3m by 4.8mInterior of the front wall of the whim engine house - thumb around the plinth. The stack, built into the southeast corner, is up to 2.5m in diameter but with an irregular radius. Both house and stack were built from killas rubble without quoins or any form of bracing. All openings appear to have had wooden lintels and failure of these is likely to account for the current condition of the building.

 

Base of the whim engine house stack - thumbnailThe separate stack was built after the whim engine house. A low flue can be traced between the two and there is a small arched opening inside the stack. TheDetailed view of the stack - thumbnail opening opposite the pumping engine house is ragged and presumably post-dates the stack. Another ragged opening faces north and a flue can be traced for a distance downhill. A calciner has been reported in the valley although no trace now exists; the stack therefore, and quite unusually, had three different purposes.
