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 it. It combines creativity with practicality, focusing on layout, color schemes, furnishings, lighting, and decor to reflect functionality and beauty. Modern interior design also emphasizes sustainability, using eco-friendly materials and incorporating biophilic elements that connect indoor spaces with nature. By blending form and function, interior design transforms ordinary spaces into ones that inspire, comfort, and resonate with the people who inhabit them.
