In my story, a valley has been flooded completely (it's the result of a spell, so that part doesn't need to be terribly plausible), leaving a house underwater save for the loft.
Would it be possible to open the front door of the house despite the pressure of the water? To unlock it? If it makes any difference, the door is heavy and wooden.
Googling seems to suggest that the house might collapse, is this true? How long would it be safe for my characters to stay in the house? Again, if it makes adifference this is a considerably old house, mostly built from stone.
Is there anything else I need to consider?
Thankyou in advance for any help.
