Interior design is the art and science of enhancing the interior of a space to achieve a healthier and more aesthetically pleasing environment for the people using the space. It involves conceptualizing and planning the layout, furnishings, color schemes, materials, lighting, and decorative elements within a space to create a harmonious and functional interior that meets the needs and preferences of the occupants. Interior designers typically consider factors such as ergonomics, safety, sustainability, and cultural preferences when designing spaces for residential, commercial, or institutional use. The goal of interior design is to optimize the use of space, improve its functionality, and create a visually appealing atmosphere that enhances the quality of life or productivity of those who inhabit the space.
