One issue with wanting a big house in Palo Alto is that most of the lots there are fairly small. There's not that many lots that can accomodate a larger home, so at best there's not many options, and sometimes there are none.

Not for a reasonable price, anyway. There are some homes that have added basements to get the space, but now we're talking something like $6 million, if not more.
