For the TS submission I am focusing on these first four flying buttress extensions in detail.
Even though I've been avoiding to have arches in this extension of the cathedral not to be imitating the old building, For the large spans I would prefer to have arches instead of diagonal crossing steel which makes the building very much look wild / out of context.
More like a spider-web, every perpendicular plane can be stabilized with the use of these arches also across the flying buttresses.
