The desk is open on the right side enabling him to work unobtrusively with his assistants. By placing as many tools as possible on the left wall panel a layout that allowed him to reach for his tools easily and comfortably, with his left hand- his dominant hand, was achieved. The “adjustable shelf system”, as used in stores, was employed. Grooves were cut vertically at 85mm intervals on the partition walls. Shelves and equipment of varying sizes can be mounted on the grooves, making it possible for Mr. Matsui to freely configure, to his liking, items like glasses, pens, cups, and books.
