I must say, the Grid Layout is one I often see used by large format stores. In fact, some smaller stores still use this type of layout. A grid layout is characterized by columns and rows all arranged in an orderly fashion. Shoppers prefer this type of layout when buying functional items. Hence, you will see supermarkets, bookstores, hardware stores, some electronics store and furniture stores follow the rows and columns pattern. However, in order to differentiate and elevate the functional buying process, I find that mixing up this grid layout with some other pattern can yield a better shopping experience. How about a circular area in the middle? Can you envision how this softens the layout with curves? A free-flow section by a corner to make it more interesting? Can you come up with something creative to enhance the grid, making it into a combination type layout?
