That looks great, but I couldn't work in an office with such a large window and no blinds. The glare would be too much.I'd retreat with a laptop to one of those circular objects and shut the door.
In other words, Google does not believe in privacy.
That's a bit of a crazy jump there ;)
Open workspaces are extremely common and very popular for companies (at least in my experience - and I have been in quite a few offices :)). Google seems to extend it to top management too - which is unusual.
I think the theory is solid btw (in that it does work in improving the work ethic etc.)
