Spatial planning is an essential part of the interior design process. It is the art of arranging a space in order to create an efficient and aesthetically pleasing environment. It involves considering the size, shape, and function of a room or space in order to create a layout that will best serve its purpose. Spatial planning should always be done at the very early stages of a project so that designers can plan out their ideas before they start working on them. This ensures that all elements fit together harmoniously and are tailored to the needs of the client.
