The Latin word for house is casa (or sometimes domus - cf. domestic in English). The word house is of Germanic origin.
Domus
The Latin root word for 'house' is "domus."
Est domus means "the home".
There are a couple of possibilities. "Villa" is the latin word for a house but "domus" meaning home can also be used however I think that is generally for more transitive or possessive purposes.

A patrician's house was called a domus, the same as any other Roman house. In ancient Rome, a house was a house, its size didn't give it a special name. The only special indication of housing was the "insulae" or apartment houses, which connoted multi-family dwellings rather than private homes for one family.
Domus Sanctae Marthae was created in 1996.
