A range of art books are the specialty at bookshop NADiFF a/p/a/r/t in Shibuya, Tokyo. We attempted to create a flow of people strolling through the space while browsing through books as they pleased. This project was the first time for us to use our method of pouring colored-epoxy onto the floor to be solidified flatly. During the process of resin flooring, a stray cat popped into the site and her paw prints are kept vividly on the floor, providing an accidental charm.
