An in-line kitchen, also known as a single-wall kitchen, is designed along a single wall, optimizing space in compact areas. This layout aligns all appliances, cabinetry, and work surfaces in a straight line, providing an efficient workflow for small homes or apartments. Its streamlined design maximizes floor space and often includes upper cabinets or shelves for additional storage. Though limited in counter space, it remains a popular choice for its simplicity, cost-effectiveness, and ability to blend seamlessly with open-plan living areas.
