casacasas

Casacasas is not a widely defined term in formal reference works. It appears as a compound formed from casa (house) and the plural casas, and is sometimes used in informal speech within Spanish-speaking communities to evoke ideas of multiple or nested housing. There is no universally accepted definition or standard usage in planning literature or dictionaries.

Because casacasas is informal and context-dependent, interpretations vary by domain. In housing discussions, it has been used to describe arrangements that blend private and shared spaces, such as cohousing or interlocking, multi-unit dwellings. In cultural or commercial contexts, casacasas may appear as a brand name, a fictional place, or a stylistic term without a fixed meaning.

Etymology and notes: the term combines casa with the plural casas; its current usage is informal and inconsistent across regions. See also: cohousing, modular housing, nested housing concepts.
