In a recent blog post from the Solomon R. Guggenheim Museum, curator Ashley Mendelsohn explores unrealized design details from Frank Lloyd Wright’s iconic design in New York City, based on blueprints and drawings from the museum’s archives. From large-scale questions of form to material choices, the 16-year period between the commission and the completion of the museum saw many design iterations. Most notable of these are the circulation paths drawn by Wright in the 1953 blueprints that include a steeper circular ramp—in addition to the “Grand Ramp”—that would allow for expedited access to the floors. Though replaced later with a triangular staircase, the “Quick Ramp” demonstrates Wright’s exploration of overlapping geometries.
