That located in Taichung, Taiwan, Taiwan Tower was designed by Dorin Stefan Birou Arhitectura, The competition brief stated that all entries must reach at least 300m in height and feature ‘a similar programmatic function as the Eiffel or CN Tower’. In answer to this, the winning submission combines eight observation decks capable of holding 50-80 individuals and affords views across the city of Taichung to the Taiwan Strait, which separates Taiwan and China.
Each observation ‘bubble’ is self-sustained by helium balloons, wrapped in polytetrafluoroethylene (PTFE) and arranged to glide on a vertical track in a strong electro-magnetic field. A key constituent of the challenge was for the tower to incorporate the sustainability factor.
Rainwater is collected and transferred to tanks in the basement to be reused for washing, irrigation of the one hectare landscape and running water for the bathrooms.
