Which of the following is NOT one of the four coliving typologies in Madrid?

The correct answer is commercial, as it does not fit into the established typologies of coliving spaces in Madrid. Coliving typically refers to shared living arrangements that focus on community, collaboration, and shared resources among residents. The four recognized typologies help categorize these types of communal living settings, focusing on different features and structures.

The unifamiliar typology refers to single-family homes that have been converted to accommodate multiple residents, highlighting a smaller, more intimate community environment. Plurifamiliar refers to multi-family units, which are slightly larger and may cater to more residents while still promoting a sense of shared living. Comunitaria captures the essence of communal living, emphasizing shared spaces and communal activities that enhance interaction and community bonds among residents.

In contrast, "commercial" does not align with these typologies since it typically implies a focus on business or profit rather than community and shared living experiences. Thus, it is not considered a type of coliving arrangement in the context of coliving typologies in Madrid.
