The Japanese House (with Karl and workers) in early stages of rescue. There were no interior stairs; the upper floor had to be accessed by ladder! After the first wave of restoration of The Japanese House.
This is the state in which I found the house, kilns and teahouse in 2010.
These are photos from the 1970s when the Hara family lived there, with photos of the kilns and a pottery exhibition in the garden. Click to enlarge.
