Tan Cottage is a Grade II listed building in Plympton, Devon, England.

[3] In the interior, during renovations, a granite corbel was discovered, part of an older wall sitting behind the modern one.

The lintel that it supported stretched into the adjacent property to the north, which continued up to Fore Street and the marketplace.

During demolition of the property's shed, the top of a moulded granite window with at least two lights was discovered.

Plymouth city archaeologist Keith Ray believed the stone came from the Hurdwick quarry at Tavistock Abbey, at nearby Roborough, which was active from the 12th century.
