The synergy of space, materials, and lighting. Space optimization is the core challenge of store decoration design. Material selection should consider both cost and performance: floor materials should consider wear resistance (such as anti slip tiles for restaurants), wall materials should pay attention to easy cleaning (such as latex paint or metal plates commonly used in retail stores), and top materials should balance the requirements for shielding pipelines and floor height. Lighting design needs to be layered: basic lighting (such as tube lights) provides uniform brightness, key lighting (such as spotlights) highlights product displays, and decorative lighting (such as light strips) creates an atmosphere.
