Maybe someone said that a contemporary home is the same as a modern home. There is nothing wrong if you remember a few similarities: minimalism, firm line structure, and an open impression.
However, some say contemporary and modern designs are different. Modern house design refers to the design of houses that emerged in the early 20th century until the 1950s. Then you can say that Art Deco in the 1920s, mid-50th century, and 1970s had a modern style.
