Formal:
* Notre maison: This is the most common and literal translation.
* Notre foyer: This is slightly more poetic and refers to the hearth or home as a place of warmth and comfort.
Informal:
* Chez nous: This is the most natural and informal way to say "our home." It literally means "at our place."
* Notre nid: This is a cute and affectionate way to refer to "our home" and means "our nest."
The best way to choose the right translation depends on the context of your sentence and the level of formality you want to achieve.
