The bathroom is that covered box in the corner. With this house, I also like the economy of documentation. A Japanese carpenter could build this house from these three drawings. I particularly like the sheet of details in compressed plan.
Shinohara’s residential output is usually discussed in terms of his own categorization as having four distinct ‘styles’ but remember that those were the days when all Japanese architects were adept at interpreting their own work and generating elliptical theories. Seeing everything in terms of those four styles I think prevents people from making up their own minds and seeing other things that might be of value. It’s generally good to be sceptical about anything an architect says about their own buildings.
But it is true that Shinohara’s 1970s houses did become more white, more geometrical and more self-conscious with names such as Uncompleted House, Sky Rectangle, Sea Staircase, etc. Early on in his career, he did say “Houses are Art” but I think he meant he wanted his houses to be thought of as Art. Hence the artwork names. Some may be artworks but on what level is a question never asked. Given the photographs Shinohara approved for publication, it doesn’t involve the uncontrollable messiness of living. My impression is that if something could not be aestheticised then it was of little interest to him.
