It sounds to me like you actually have two distinct objects here, Address and Location. A Location could be used to represent a corporate office or some other conceptual place, but an Address would be a value object that represents a physical location. An Address never changes, even if the purpose of the Location changes.

An Address never changes, but the Address property of a Location can be changed from one Address value object to another with an appropriate event.
