architect santiago calatrava is currently working on the chicago spire, a massive 600m skyscraper that will
dominate the chicago skyline when it is complete in 2011. the building will have 150 floors featuring around 1,000
residences and will be the second tallest building in the world. unlike other tall buildings which are multi-functional
the project will be an all residential building.
the twisting design of the chicago spire was inspired by nature, as most of
santiago calatrava’s work is. particular influence was drawn from the spiralling shape of snail shells. each floor is rotated 2.44 degrees
from the one below it, totaling 360 degrees. sustainably speaking, the building is planned to receive a gold LEED
the apartments that are found in a building of this monumental stature are definitely not cheap. indeed, rent prices range between 750,000
and 40 million USD.
