What type of development typically includes public spaces, shops, and residential units?

Mixed-use development is characterized by its integration of different types of land uses within a single project or area. This typically involves a blend of residential units, commercial spaces such as shops and restaurants, and public areas, all designed to promote a vibrant and cohesive community environment. The goal of mixed-use development is to create spaces where people can live, work, and socialize in close proximity, thus reducing the need for extensive transportation and fostering a sense of community.

In contrast, suburban development primarily focuses on low-density residential areas, often lacking the comprehensive integration of services and amenities found in mixed-use developments. Industrial development revolves around manufacturing and production facilities, with little to no emphasis on residential or commercial spaces. Greenfield development refers to the construction on undeveloped land, often outside urban areas, which can include various types of projects but does not inherently include the mixed-use aspect unless specifically designed that way. Hence, the distinct features of mixed-use development, with its emphasis on combining living, retail, and recreational spaces, make it the correct answer.
