It's the chieftan's mansion, and Ghira didn't become chieftan of Menagerie until after he stepped down as leader of the White Fang. It has been expressed in-show that, when Ghira and Kali left the White Fang and Ghira became Menagerie's chieftan, Blake stayed with the White Fang and thus did not go with her parents.

In other words, Ghira and Kali didn't move into the chieftan's mansion until they left the White Fang, and because Blake didn't go with them, she did not live in that mansion.
