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 involves a multifaceted process that begins with understanding the client's needs and objectives. Factors such as lighting, ergonomics, color schemes, and materials are carefully considered to create a cohesive space. Space planning is crucial to ensure optimal organization and functionality. The final design typically includes 2D plans, 3D visualizations, and a selection of materials and furnishings. Collaboration with the client is essential to ensure that the end result reflects their personal preferences and lifestyle.
