Interior designers operate more on the architectural side of building projects. In conjunction with architects, they work on the design of a building or home to best suit the needs of the users or residents. Interior designers are generally experienced in construction and understand how architectural planning works, according to NewSchool of Architecture & Design. And some interior designers will perform the duties of an interior decorator.
Interior decorators, on the other hand, work with fabrics, accessories, furniture, art, colors, textures and materials to make the inside look fashionable and pleasant.
