spudart.org made a cool post about doubling the Aon building's height. It's inspired by the fact that Aon's neighbor, the Blue Cross building, will actually be doubling its height over the next couple years. He asked for a Double Hancock. Well, here you go.
Oh and I mean like a view of the entire skyline. Your view is from down below the hancock. I want to see a double-hancock from a skyline perspective. Do you think the angled lines in the building would merge at the top.
Also, how tall would the hancock have to be where the angled lines would finally merge? My guess is that you'd need to stack 2.5 more hancocks on top of the current one to make the lines merge.
