Three-level supermarket design refers to a layout strategy where a supermarket is divided into three distinct levels or floors, each serving different customer segments and product categories. This design aims to optimize shopping experience and maximize sales. Typically, the ground floor is dedicated to fresh produce, bakery, and ready-to-eat items, the first floor to dry goods and household items, and the second floor to electronics, appliances, and leisure products. This approach allows for efficient traffic flow, easy navigation, and targeted product placement.
