I have heard Eric Schmidt say that he discusses Google's preference for on-site employees in _How Google Works_. I cannot comment on what or how much he discusses.
That said, my personal experience at Google has been flexible. Most people I interact with work from their home office most of the time with large schedule overlap with their colleagues. But people do shift their schedules as life needs and occasionally work from other offices for up to a couple weeks a year.
