Interior design is a multifaceted field that enhances the aesthetics and functionality of interior spaces. It builds on architecture's foundations by using color, texture, lighting, and materials to create environments that align with occupants' needs and preferences.

Interior designers make spaces visually appealing, functional, and safe, determining space requirements and selecting decorative items such as furniture and artwork. They collaborate with clients to optimize space use in residential settings, creating cozy living areas and efficient kitchen layouts. In commercial spaces, they design layouts that promote productivity and brand identity.

Interior designers must adhere to building codes, safety regulations, and accessibility standards, often working with architects and contractors to ensure their designs are executed perfectly.
