One Less Door on Smith Street

Here's an interesting sight. A partially brick-up, old door on a building at the corner of Smith and Union streets in Carroll Gardens. Very Edgar Allen Poe. That door's been there for years. Don't know how it's made itself so inconvenient that it has to be erased. Now, do they brick up the inside, too, or does it become one of those cartoon exits where someone opens the door and runs smack into a brick wall?
