Answer : Interior design has changed over the years as society's values have shifted and new materials and technologies have become available. For example, in the 1920s and 1930s, interior designers favored sleek, modern designs with lots of chrome and glass. During the 1950s and 1960s, there was a trend towards more natural materials like wood and stone, and during the 1970s there was a move towards "soft" colors and textures.
More recently, there has been a trend towards using more neutral colors and earth tones, as well as using less furniture and more space-saving designs.
