Mostly materials used from the house renovation (except roof, paint and nails). Inside walls made from wattle & daub with lime wash. My wife calls it the A Ba Ra Ya Shed (wobbly in Japanese as hardly any straight lines) whilst I call it a Japanese tea house, so I may have disqualified us? Veranda around follows the sun through out the day. Built in 2020 during lockdown.
Using as much natural and reclaimed materials as possible, including the soil/sand/clay from the garden. It has a earthly feeling inside and makes me feel like pre-historic man. The accompanying music band to the youtube video is Yo La Tengo: sounds normal to say after " A Ba Ra Ya" after a few beers, and great music to listen, sitting on the veranda with a beer, yakitori and sun setting.
