In Guli, a place of Jiangnan water town, Mur Mur Lab got a precious chance to design a small bookstore in a traditional house. Future Bookstore focus on the inspiration of the undetermined, hiding, and impermanency. Under the old traditional roof structure, Mur Mur designed another new roof. The new roof is like an unfolded book roll, spreading through the whole space. Two roofs shared similar logic of form, the ridge, the inner and outer cornice and clear volume of two slopes. Besides the comparability, it seemed to be completely unacquainted. Leaving the obvious outline of geometrical rules behind, the new roof composed a flow of curve in coherence with the river outside. The eave is going up and down, some are like a welcoming gesture, while some are like a protection screen. The circulation is designed to connect books and people together. Instead of pile of books, there are only several books showing on a transparent shelve. The way of obtaining knowledge changes from real books into more versatile information media. Space itself will tell the story, in an old, silent, monologue way of sensing and feeling. The Future Bookstore is a mini transmitter of imagination, bringing the experience of aesthetic to people in a graceful way.
