Interior design is the thoughtful planning of spaces to enhance both daily comfort and visual harmony. It focuses on how people move, relax, work, and interact within an environment, ensuring that every element supports a smooth lifestyle. From spatial layout to lighting placement, each decision influences mood, efficiency, and long-term satisfaction. A well-designed interior does not feel forced or overcrowded; instead, it feels natural, balanced, and welcoming. When design aligns with human behavior, a space becomes easy to live in and emotionally fulfilling.
