In the US, I think this comes down to the developer. When a developer creates a neighborhood, they usually give it a name. And that name usually sticks. Likewise, when a developer creates a larger building, they might give it a name. And that name will probably stick for as long as that original owner continues to own it. But there is also a major branding exercise here — look at the names of sporting arenas. It’s “Dodger Stadium” until Oracle decides to pay enough money to change the branding, and then it’s “Larry’s Private Blue Field Oracle Stadium That Is Occasionally Used By The Dodgers” or whatever the hell they decide to use. And that sticks until the term is up and someone else pays the license fee to change the name again.
