I had a joinery workshop at the time and I made all the Bathroom timber fittings and fixtures including the glass sliding window which was approximately 1800 mm x 1800 mm.
I used to live and work in Japan so I was happy to build something I could identify myself with. When you read the article you will see all the people involved but unfortunately I wasn’t mentioned as the builder. I will try to dig up some photos that I might have of the early stages of work. Here are some photos of builder John helping me out.
