OK so the story here is that Walter Carroll wrote a famous music book for training children in piano. It's called "Scenes at a Farm" and it was used for decades, still is. The farm that it's based on is apparently this one attached, although you can't see much as it's covered in a landfill's worth of snow. Not sure where this farm is but it was the inspiration behind one of the most useful pieces of music ever to come out of a Manchester composer.
