Volutes is a skyscraper conceived by Asami Takahashi and Jason Lim located in Singapore’s new marina. Our proposal is to pull upwards the urban fabric and create a helical volume. Public programs are wrapped around a central circulation core while six serpentine structures contain the private spaces. The morphology of the building results from the analysis of 6 control lines sweeping around the central core. The outer skin is linked to the main structure with spokes arranged in a hexagonal configuration.Volutes opens at the street level and closes at the top to allow direct sunlight into the city. Its porous skin maximizes ventilation and regulates the green parks and water reservoirs.
