Mixed-use development refers to a type of urban planning that combines residential, commercial, and sometimes industrial spaces within a single area. This approach aims to create vibrant communities where people can live, work, and play without needing to travel long distances. By integrating different types of buildings and services, mixed-use developments promote convenience and accessibility. These developments often include amenities such as parks, shops, and restaurants, fostering a sense of community and encouraging social interaction. Examples of mixed-use development can be seen in urban areas like New York City and San Francisco, where neighborhoods blend housing with retail and office spaces.
