400-meter high freestanding Mix Use Tower, born with the mission to create a pioneering and innovative design concept which will stands as a new-age landmark and a symbolic voice to the word of Taiwan’s new spirit. The proposed shape links the required program with some inspirational features such as the Eiffel Tower (structure and icon), the Origami (symbol generation) and Taiwan’s star-look flag (identity). The massing development had in consideration the need to become the most visual focus and the new gateway image for Taichung area, so the building perception is different from every corner and establish renewable relations with the city from within the building and from the outside context.
