The difference between what it is and what it appears to be

House in Moriyama, Aichi - June 2009
Suppose design

It's very strange how from the outside it looks like a bunker! While inside... such a wonderful place, it's seems an oasi.
It's very interesting how in the interior of the house it's been created two casings: the first one full of plants and gravel, the second one totally glass and here the real home takes place.
