I recommend watching this YouTube video that details the Apple Headquarters. Amazing detail of their working space though I think I would have also been one of those that bumped into the glass!

Thanks Georgia, I'm off to explore. Drones with cameras flew over the site roughly every month from the first foundation digging. I guess these videos are still available on YouTube or elsewhere. UK Architect too!
