Planning a wide studio or an open-plan living room without dividing walls starts with zoning: deciding what each area is for, then grouping the furniture, rugs and lighting that belong to it. Cluster a sofa, a rug and a coffee table and that alone signals "living zone" — put a dining table and a pendant light nearby and it reads as a separate "dining zone" with no wall required.
The tools that make a boundary aren't walls but a change in flooring, the edge of a rug, the reach of a ceiling light, or which way a piece of furniture faces. Placing a bookshelf or console with its back to a walkway, for instance, turns that back panel into a natural visual divider.
Keep enough distance between zones that circulation isn't blocked, and let neighbouring zones share at least one color or material — otherwise the space reads as several unrelated rooms rather than one open plan.
When to use
Use it for studios or open living-kitchen spaces that need to hold several functions without walls. If it's still unclear where one zone ends after all the furniture is placed, check the rugs and lighting first — that's usually where the boundary got lost.
