I've been working remote from home for 15 of the past 18 years.
Taking it a step further, the biggest problem with "my door is shut, I'm at work" is that I sometimes need to open my door. Perhaps for lunch or a snack. Or just to stretch my legs and think. Just because my family sees me wandering around the house doesn't mean I'm available.
I've found that it works best to have my wife & kids email me questions/info/thoughts even though we're in the same house. I can then respond when I'm available. Sometimes via email or sometimes by initiating a conversation.
