Most common:
* Maison individuelle - This is the most common and literal translation. It emphasizes the "individual" aspect of the house, meaning it's not part of a larger structure.
Other options:
* Maison isolée - This translates to "isolated house" and focuses on the house being physically separate from other buildings.
* Maison non mitoyenne - This literally means "house not sharing a wall" and emphasizes the lack of a shared wall with neighboring houses.
* Pavillon - While not directly translating to "detached house," "pavillon" often refers to a detached, single-family home.
Ultimately, the best translation depends on the specific situation and the desired emphasis.
