Interior design exhibition in Moscow. Interior design is all about style, quality and personal preferences; but finding an inspired 'look and feel' to suit a client's brief, and delivering precisely what a client wants even when they can't describe it themselves is never easy. Interior design is a complicated profession. It is sometimes referred to as interior architecture and often confused with interior decorating. It involves the design, organization and planning of an interior structure rather than just refinishing and furnishing existing interior spaces. It involves managing a business, hopefully meeting the desires of the client and delivering to them an interior environment that is both functional and aesthetically pleasing.
