    Really nice project. Simple, elegant and clear. And what a couch! I’m not sure how the shade-less bulbs will work, though, unless they’re pretty dim (which they may be). But a full-watt bulb just hanging there would be hard to look at, right?

    I really admire the simplicity. A fine way to live.

    I just don`t like the toilet in the middle of the house sticking out from the rest of the rooms. I keep on thinking that while i am playing my sonata someone will flush the toilet! Although it does makes a nice corner for the piano i think it is a bit clumsy in terms of hierarchy of function/form.It could have been intergrated differently…what do you guys think? Very un-japanese and unlike Tezuka to have clumsy plans! Nevertheless the house is an achievement!

    It reminds me of some of the New Zealand “shed” bach designs, that open up completely to nature. eg Ken Crosson

    Rubbish. Very Japanese in that it embodies their inability to scrap a bad idea once inertia takes over.

    Unjpapanese? Most japanese houses have the toilet close to the front of the house. It originates from not so long ago when there was not sewer systems and the pit had to be cleaned out on a regular basis, so the toilet had to be immediatly adjacent to the street.
    Looking at the plans it appears the walls are thick enough to be soundproof and modern j-toilets are pretty quiet.
