Apply minimalist design in small city apartments by focusing on smart composition and maximizing negative space. Use multifunctional lighting like pendant cords arranged artistically on walls to serve as decor. Curate fewer but impactful pieces to avoid clutter, and keep color palettes restrained with soft neutrals. Incorporate built-in storage and low-slung seating to preserve openness. This approach creates a calm, layered living room that feels spacious, serene, and thoughtfully designed.
