Interior architecture is the design of interior spaces with an emphasis on the architectural elements that define a space, such as walls, floors, and ceilings. It involves the creation or alteration of interior spaces to achieve a desired aesthetic, functional, and environmental quality. Interior architecture is also known as interior design, although some professionals in the industry make a distinction between the two, with interior design focusing more on the decorative aspects of a space, while interior architecture places greater emphasis on the technical and structural aspects of a space.
