The term Spanish House can be broken down into two words, HACIENDA (8 letters) and CASA (4 letters). A HACIENDA is a large estate or plantation in Latin America, typically owned by a wealthy family. It is usually used for agricultural purposes such as raising livestock or growing crops. A CASA is a house in Spanish, and is used to refer to any type of dwelling, from a small cottage to a large mansion. In Spanish-speaking countries, the term CASA is often used to refer to a family home.
