What it was
An unbuilt environmental megastructure proposed by Buckminster Fuller and Shoji Sadao.
The transparent dome would span Midtown, shedding snow, moderating climate and enclosing existing towers without replacing the city below.
Existence timeline
Fuller and Sadao imagine a geodesic envelope across Midtown.
The transparent hemisphere appears over the existing skyline.
The designers argue that climate control would offset construction cost.
Fuller uses the dome to advocate comprehensive resource design.
No authority adopts the shell as an executable urban project.
Never Built New York presents the project to a new public.
Why it ended
The scheme functioned as a speculative demonstration of geodesic efficiency and never received a governmental, financial or construction mandate.
Last confirmed trace
Photomontages, drawings, models and Fuller's written calculations survive in archives and exhibitions.
What it left behind
The image became shorthand for both technological environmentalism and the seductive danger of solving urban life with one enormous object.
How we classified it
The proposed archive unit never reached ordinary public access in the form being documented.
The strongest verified milestone maps to documented_concept under Arrival Score V1.
