Can NPC houses have two doors?

In Terraria game, we can build houses for NPCs. They must be at least 8x5 from inside, and surrounded by walls and blocks. It must also have a chair, a table and a door.

But... Can it have two doors?

Two doors can be convenient, so we can access the house from either side, or even walk past it.

Solution 1:

The Terraria NPC houses only really care about the minimum requirements. You can go much grander if you'd like, for instance.

My Merchant actually lives in my dining room.

Three stories, two doors -- as long as it meets the minimum requirements, they'll move in. They ain't picky, either.

Solution 2:

Yes, they can. I like for my houses to be symmetrical and so I always have a door on each side. It works just fine.

Solution 3:

Yes, NPC houses may have any non-zero number of doors.
