I love the tradition of naming the family *cough* estate, as it 'twere.
My house was built in the fifties, three bedrooms and a bath and 1/2. NO WHOOP.
BUT I like pretending it's an English country cottage so I call it Hosa House as we've loads of hosta around (only thing that can really survive our absolutely horrid summers) - not that this has caught on, mind you, but it's fun to pretend. I have heard of one american house being called Loose Pilings - but I'm fairly certain a murder happened there and I can't compete with that.
what would you call your house if you have your druthers?
I've also thought of calling the place Brokedown Palace - but it's so far from a palace that it wouldn't even be ironic.
