Phoenix Observation Tower by BIG

Danish architect BIG has been commissioned to design a dizzying 420 ft tall observation tower in Phoenix, Arizona. Visitors to the Observation Tower will be able to enjoy 360 degree views of the surrounding mountain ranges in downtown Phoenix. This colossal piece of work is conceived as a tall core of reinforced concrete with an open-air viewing deck at the top. A spiralling promenade wraps itself around the concrete structure, containing flexible exhibition, retail and recreational spaces, plus an unforgettable view.
