I felt differently when I visited. If anything, they at least show a progression over the general phases of the campus. Buildings 1-9 are very similar, as are the triangle buildings 16-18. A lot of the newer buildings (ie the 'Studios') are almost exactly the same. There are a few other buildings on campus (late 20's or 3*?) that show a similar architecture to the studios. But then, there is 'Red West' which is its own little mini campus in terms of design.

The reason I asked was because I wanted to see Microsoft categorized in such an easy and quick manner as Google/Apple. I must admit that I myself can't do that.
