Happier Mart is an offline store developed by Oh!Lolly day! with the motif of small but substantial supermarkets in Korea. This is the second project after the Pangyo branch, located in Seongsu. Since supermarkets have to change the display of products from time to time, the space is designed using perforated plates and channel shelves manufactured to specific standards, allowing for easy modification of product displays. Additionally, the counter is designed in the form of an extruded booth for smooth communication.
