An open floor plan is a design concept that combines multiple living spaces into one large area, typically merging the kitchen, living room, and dining room. This layout promotes a sense of spaciousness and encourages social interaction, as it allows people to move freely between areas without walls obstructing their view. Open floor plans are popular in modern home design because they can make smaller spaces feel larger and more inviting. They also provide flexibility in furniture arrangement and can enhance natural light flow throughout the home, creating a bright and airy atmosphere.
