Interior design refers to the process of shaping and creating interior spaces that are functional, aesthetically pleasing, and tailored to meet specific needs or preferences. It involves making strategic decisions about space planning, furniture selection, color schemes, lighting, textures, and materials to create an environment that is both beautiful and practical for the people using it. Interior designers work with a variety of spaces including homes, offices, hospitals, schools, hotels, and restaurants, taking into account factors such as ergonomics, safety, and sustainability while also considering the psychological impact of space on its occupants. Ultimately, interior design is about creating an environment that enhances people's lives by providing comfort, functionality, and aesthetic appeal.
