The three tiers (the "Corona") of bronze, porous, pumice-stone-like material still form the bulk of the structure. What was originally a large base of the building, the "Porch," has been mostly pushed below grade so only the top pierces ground level, a concession to the prominence of Washington's Monument. The raised platform will retain its mezzanine functionality as a place to install skylights to illuminate below grade programming. Planners are proposing to mound the earth around the structure to replicate the sloping dimensions of the neighboring Monument grounds.
Overall, the building's footprint and profile have been reduced, and adjusted slightly to the south, to diminish the perceived brutish visual intrusion of the building as initially rendered. Although the designers admit that this new position shifts the building a bit offline from the center alignment of existing museums, the changes were made to create a less obtrusive structure, and allow more open sight lines to and pleasantly framed views of the Washington Monument from Constitution Avenue.
