The mixed store layout combines design elements from various formats to give retailers a flexible option. Department stores use a compelling combination of straight, diagonal, and angular concepts, among other design elements, to create a dynamic flow through various departments featuring a diverse selection of merchandise. Large grocery store chains have also successfully combined mixed store layout elements. Customers, for example, can browse a grid layout for their basic groceries but are compelled to search the angular displays featuring high-margin wine, beer, and imported cheeses. Combining different store layouts appears obvious, but the space and resource requirements to maintain this design can be difficult for retailers to meet.
