In the autumn 2012, I reserved to 'stay' at an installation "Shiranai nowa Omae dake" (You're the only one who doesn't know) by Tatzu Nishi, a part of Water and Land Art Festival in Niigata prefecture, Japan. The space was offered to book to stay over. But I stayed for less than 3 hours with CDL until I got a complaint as I did not appear to be 'living there as a normal person'... The place had very nice aural boundaries in the typical Japanese residential house setting, however, with unique voids that means it was built "without" the internal ceiling so it is 'to be viewed/peeked' by strangers/visitors.
