Explanation:

Mixed-use development in a general sense refers to - any urban, suburban, or village construction, or maybe even a sole house, incorporating a mixture of private, commercial, community, educational, or industrial applications, where those roles are visibly and technically combined, and where pedestrians links are provided.

Mixed-use designs have almost nothing unique; they've been like this for a number of years. Only walk through Mumbai's markets and you'll see them throughout.
