First thing I must write about here is the custom concrete retaining walls of the south station. If it was executed in the same way that I have seen Disney do it (once), then the forms were all custom made of bent plywood with custom cut wooden ribs holding the shape. While the big perfect half circle is something, note the nuanced curves further along. Boggles my mind.
Next, the custom bent steel work of the north station and Diagon's roofs astounds me. It makes me wonder, was it bent on site or prefabbed at another location? How engineers and/or builders got their heads around such wacky shapes and angles leaves me with a headache.
All these photos are absolutely incredible. A 1200% return on my investment!
