Interior designers are professionals who plan and create functional and aesthetically pleasing indoor spaces. They work with clients to understand their needs and preferences, selecting colors, furniture, and decor that enhance the overall look and feel of a room. Interior designers often collaborate with architects and contractors to ensure that their designs are practical and meet building codes. These designers may specialize in various areas, such as residential, commercial, or hospitality design. They use their knowledge of space planning, color theory, and materials to create environments that are not only beautiful but also comfortable and efficient. Interior designers often hold degrees in interior design or related fields and may be certified by professional organizations.
