shelf pod house by kazuya morita architecture
also see their renovation of a machiya in kyoto.
(as their commenter said: 'lots of space for books' :)
"the client owns an extensive collection of books on the subject of Islamic history,
so he requested that we create this building with the maximum capacity for its storage and exhibition...
The dimensions of each shelf are as follows: 360mm height, 300mm width and 300mm depth.
All of the architectural elements in this space (stairs, windows, desks, chairs, etc) have been designed
on the basis of this shelf scale, with the aim of achieving geometrical harmony which is comparable
to Islamic Architecture. This innovative structural system affords not only large amount of book storage,
but the possibility of flexible floor level which can be delivered from every height of bookshelf."
