What is an example of a mixed-use building?

A mixed-use building is characterized by the integration of different types of spaces within the same structure, typically combining residential, commercial, and sometimes industrial use. The correct example reflects a situation where professional services, such as therapy, are offered in conjunction with other uses. In this case, a building where therapy takes place may house offices for professionals, retail spaces, or residential units, thereby providing a blend of services and living environments.

The other choices represent individual residences, which do not incorporate this combination of functions and services within a single building framework. Therefore, solely identifying a location like a house, regardless of whose it is, does not exemplify the concept of mixed-use development that highlights the coexistence of different types of spaces.
