inthenoosphere:Ultima Tower, Eugene Tssui, 1991. “Two-mile high, tensile structure based on a tension/compression “spine” with a hollow, mirrored center, to allow sunlight to reflect from the inner core; the entire building is in tension and suspended like a giant maypole. Twelve levels are open to the sun and wind and planted with forests, rivers, lakes and hillsides. Building flexes under stress-and-strain. Houses one-million inhabitants.” (Wikipedia) -- source link
