"You are closing the door to your house."
Translation:Zamykacie drzwi waszego domu.
Number 1 doesn't make much sense as few people close the door but only one of them is the house owner. It can work when you change the person you are talking to mid sentence, but it is very stretched explanation.
Number 4 is OK IMO - you can imagine talking to a man closing the door of his and his wife's house.
ah ok drzwi is in the accusative but swojego domu is genitive because of possession right?
