Which house do you prefer ... ?

Not fond of any of them. Number one is on the side of a mountain and we could easily fall off (observe what happens in California). Number two the majority of the living space looks to be on the second. Not sure I'd want to go upstairs all the time for everything. Number 3 spreads out too far. I Am Number Four looks too much like a castle without being a castle. Would prefer an actual castle, with secret passages.
