A mixed-use building is a structure that combines different types of spaces, such as residential, commercial, and sometimes even recreational areas, all within one location. This design allows people to live, work, and play in close proximity, promoting a more vibrant community atmosphere. These buildings often feature apartments or condos on the upper floors, while shops, restaurants, or offices occupy the ground level. By integrating various uses, mixed-use buildings can reduce the need for transportation, encourage foot traffic, and enhance local economies, making them a popular choice in urban planning and development.
