[Folklore] Can a vampire get trapped in a courtyard?

Vampires need permission to enter your house, so what happens if they're completely surrounded by a house? Could you trap a vampire by building a house around them while the sleep? Or even just claiming the land?

The courtyard is part of the home as much as any other space is.  The fact that it's open to air doesn't change that.  
If the vampire is in the courtyard, he's already obtained permission to enter somehow.
