Hello, your shop is almost 7 meters deep. Generally speaking, you should put the shelves in the central island area, because the shelves are basically hung on both sides, so that your space can be maximized. You can make cabinets (cabinets) against the wall, put high and low pavilions in the island area where you enter the door, and make glass windows, models and supporting props next to the door. These are on the one hand, and other important things are supply, passenger flow and consumption power. Good luck. Open your business!
