The practice of using different carpet types or designs to define separate functional areas within a larger space. Common in open-plan environments where changes of carpet can subtly mark transitions between work, relaxation, or circulation zones without physical barriers. With area rugs, a single rug can anchor a zone where there are no walls, and two rugs can split a large living room into two functions; rugs in neighboring spaces read as connected when they share a type, design or colors, and as separate when their colors and patterns differ.
