sshhhh, be wary, wary quiet I'm hunting plaza's

So I set off to hunt down some plaza's or anything that could help me with my design for my plaza. I was amazed to see so few plaza's around the world! I looked everywhere and came up with not much at first. But I finally struck gold with the John Hancock plaza in chicago. It was a great strating point for me in terms of figuring out layouts for blockouts and designs as I already knew I wanted a circular horse shoe shaped main area to keep everything enclosed. Even though the plaza is more circular with a lot of angular stairs I have managed to take away a lot and will definitely help me in my design and block out process.
