Historic building record prior to the conversion of an outbuilding associated with a building known as The Granary, located near to Sarre Windmill. The outbuilding has been present within the Sarre Mill complex at least since the publication of the First Edition of the Six Inch Ordnance Survey in 1874, where it formed a direct part of the wedge shaped enclosure which housed the Sarre Mill and other buildings associated with its operation.
