Home is less a building and more a version of you that you can return to anywhere.

Home turns out to be a state more than a place. It is the version of you that is unguarded, steady and recognisable to yourself, and that version can be reached in a new city or an unfamiliar room once you know what produces it. People who tie it to one building lose it when the building changes.

Work out what reliably returns you to yourself: a routine, certain music, one phone call, a particular way of spending an hour. Take two of those with you when you go somewhere unfamiliar. Portability is what makes it dependable.
