To me it seems that the "Old House" is a metaphor of an old, long past relationship. Two old friends or lovers meet, many things have gone wrong in the past resulting in an uncomfortable situation where they don't know what to say to each other.
Since things cannot be talked over, they decide to just accept the company of each other, and it reminds the singer of how it used to be, and how he will always be affected by this long gone relationship ("We'll never leave, this old house"). "Every door is open" probably means that the two persons know each other very well and have no real secrets for each other.
It's a very comforting song in a way that it makes clear that how much you disagree, you will always keep certain feelings for each other and always can think of how it was, and comfort each other just by being together.
