Furniture placement mistakes decrease home value by disrupting the natural furniture flow and making spaces feel cramped or awkward. When furniture blocks pathways or focal points, it reduces perceived space and comfort, which buyers notice immediately. Ensuring clear walkways of at least thirty-six inches and orienting seating toward focal areas like fireplaces or windows creates inviting, functional rooms. Fixing these layout issues is a simple weekend project that significantly boosts buyer appeal and resale value by enhancing flow and making rooms feel larger and more intentional.
