Use texture to warm up a minimalist living room by layering tactile materials like soft textiles, fluted wood panels, and classic mouldings. Replace thick rugs with flatwoven wool to keep floors clean and inviting. Incorporate built-in shelving or subtle wall treatments that cast gentle shadows for visual interest. These textural layers create depth and softness without clutter, helping the minimalist design feel more lived-in and warm while maintaining its serene simplicity.
