Kitchens began as simple hearths, evolving over centuries into separated rooms where food prep took place. By the 1900s, with advances in plumbing and appliances, they became more functional and organized. The mid-20th century saw popularization of the "work triangle" concept, emphasizing efficiency between the stove, sink, and refrigerator. As lifestyles shifted, open layouts emerged, connecting kitchens to living spaces. From wood-fired stoves in communal settings to modular designs in private homes, kitchen layouts have always reflected society's changing needs and technological progress.
