What were Kurosian homes like? Were they like apartments? Or were they separate?

Lost Queen : We had homes, apartments, faction houses, etc. Mostly made of dark wood and stone. At the very entrance of the city, just past the sky ports, we had special inns that non-Kurosian visitors had to stay in, as you had to be a Kurosian citizen to own property within the city or even rent. There were exceptions for visiting royals of the sort, special sections were closed off within the castle for such cases.
