Expanding Sarah's questions:

1- In that regard, could the Darkwood Manor be considered a Black Door Phenomenon after such heavy spooky influences by that house's lord?

2- What about the static dungeons? They don't fade away, but are still dangerous places packed with monsters.

3- This is more a (Sam) theory, but... Would anything done to a Black Door Phenomenon be impossible to stick, due to how erratic those places are and (probably) tend to warp back and forth in time and space?
((Example: If we go up to a BDP and barricate up every possible entrance so other people can never enter it. Would it stay like this permanently, or 'by it being a BDP', it will magically reverse in time or something?))
