Is seclusion (khalwah) considered to exist if the man is on one floor and the maid is on another?

The questioner:
If you are on the second floor and the maid is on the first floor, and you have locked the door between us, is this considered seclusion?

The Shaykh:
Yes, as long as you are in the same building with a single entrance, even if it is divided into sections, this is considered seclusion. However, if she is in another house with a separate entrance and the door between her and you is locked—although the door alone is not sufficient, as it might be opened—the result is that she is in one house and you are in another, and you are not in the same house or in apartments with a single entrance. Yes.

The questioner:
The questioner says: A man married a woman, and this woman...

The Shaykh:
The apartments were private to the owner of the house. But if the apartments are in a large building where people live, this is like multiple houses. If it is a large building where people usually live in these apartments, this is like multiple houses. Yes.
