Has it been discussed, or does anyone have any idea, what this square portion to the left of the arch will look like when all is said and done? It doesn't seem to match the design of the real-life Kings Cross, unless they are playing with the proportions.
Could this be the originally rumored St. Pancras facade? (Although, I don't know how they would pull off a hybrid of the two, with their drastically different architectures.)
And what will they do to obscure the view of that second iteration of the KC arches (Platform 9 3/4)?
