Modern architecture is characterized by its use of simple lines, open floor plans, and natural materials. It was a reaction to the ornate styles of the past and sought to create a more functional and aesthetically pleasing style of architecture.

Here are some key features of modern architecture:

• Simple lines: Modern buildings are often characterized by their simple lines and geometric shapes. This is in contrast to the ornate styles of the past, which often featured elaborate ornamentation and decoration.
   
• Open floor plans: Modern buildings often have open floor plans, which means that there are few interior walls or partitions. This allows for a more free-flowing and functional space.
   
• Natural materials: Modern buildings often use natural materials, such as wood, glass, and concrete. This is in contrast to the use of more expensive and ornate materials, such as marble and gold, in the past.
   
• Function over form: Modern architecture is often said to prioritize function over form. This means that the design of a building is based on its intended use, rather than on its aesthetic appeal.

Here are some famous examples of modern architecture:

Villa Savoye in Poissy, France: Villa Savoye is a modern house that was designed by Le Corbusier in 1929. It is characterized by its simple lines, open floor plan, and use of natural materials.
