Helicoidal Skyscraper

Texte de Wikipédia en anglais, en attente de traduction.

The Helicoidal Skyscraper was a planned but never materialized, 565 m (1,854 ft) high business center that was to have been built on the tip of Manhattan, New York City. It was a stillborn project developed between 1968 and 1974 by Italian architect Manfredi Nicoletti. It combined its aerodynamic shape with the technology of wired bridges, for the purpose of minimizing both the loads and structural bulk.
