While I understand the logic behind designing the building as a ring to promote serendipitous encounters, I'm quite curious about how the interior layout will function and how they plan on optimizing getting around.
They'll likely arrange departments that will most often interact with each other in close proximity to one another. But that doesn't mean that someone on one side of the ring won't need to meet with someone on the opposite side of the ring. Every department has a Vice President, all of which who need to meet regularly with their managers, with Tim Cook and with each other.
The circumference of the ring has been estimated to be 4,778'. Given that one would only have to walk half the length in one direction or another to reach a point on the opposite side (while staying in the building), that's still about half a mile, or a 10-15 minute walk with no stops. That's a long walk to get to a meeting!
So how have Steve Jobs, Norman Foster and Jony Ive envisioned that people will get around efficiently? Are they just assuming that people related to one another will mostly stay in the same section and only occasionally have to walk far? Are they installing moving walkways? Is Jony Ive designing an internal use only Apple "Hoverboard"?
Granted, the exterior is beautiful and an awe inspiring piece of architecture and engineering, but the interior is going to be absolutely fascinating!
EDIT: Plans submitted to the City of Cupertino mention that there will be 1,000 bikes kept on the campus to get around. A rendering also shows that there's an indoor track on the outer periphery of the building:
But bikes? Jobs must have not envisioned the rise of the "hoverboard" in 2016.
