This would be an example of Mixed-use development.

Explanation: Mixed-use development is a development that involves either the conversion of old buildings into buildings that can serve the purpose of mixed use, or the creation of new buildings that will serve this purpose alone.

Mixed use refers to different uses, for instance where a single building houses an apartment, a studio, a firm, a doctor's office, etc.

This development can be undertaken by a private developer, government, or both.
