Site of a former building which contained machinery associated with the clay pit at Left Lake. The building was prefabricated, probably corrugated sheeting on a timber frame, built onto a concrete base. All that survives is the concrete base of approximately 7 metres by 7.5 metres which has an extension on the southern end of 3 metres by 3.45 metres. A low concrete foundation wall of 0.22 metres thick survives in places around the perimeter of the base. A raised concrete platform within the building with threaded vertical studs in situ, housed machinery, possibly an engine associated with winding or pumping within the clay pit. Clay was extracted from this site for a short period in the 1850s, but this building was installed between 1911 and 1932 when operated by the China Clay Corporation and later the Ivybridge China Clay Company.
