How do I say the house is called in french?

There are a couple of ways to say "the house is called" in French, depending on the context and formality:

Formal:

* La maison s'appelle... (The house is called...) - This is the most common and formal way to say it.

Informal:

* La maison est appelée... (The house is called...) - This is a less formal option, but still grammatically correct.

Example:

* La maison s'appelle "Le Château". (The house is called "The Castle".)

* La maison est appelée "Le Petit Nid". (The house is called "The Little Nest".)

You can also use the verb "se nomme" instead of "s'appelle" for a slightly more formal and old-fashioned tone.

* La maison se nomme "La Belle Epoque". (The house is called "The Belle Epoque".)

Remember to use the appropriate definite article ("la" for feminine nouns) before "maison" when referring to a specific house.
