Layout is critical in wide living room nooks near fireplaces to ensure comfortable viewing, clear traffic flow, and balanced aesthetics. Poor layout can cause awkward sightlines, blocked pathways, and clutter. Positioning the TV in the nook with base cabinets and shelves creates a functional media zone apart from the fireplace, which serves as an artwork or mirror backdrop. Ensuring a clear 36-inch path around furniture promotes easy movement, making the living room practical and inviting.
