Bjarke Ingels Group (BIG) has released their most recent design project – a 420ft-high observation tower in Phoenix, Arizona. Phoenix is renowned for its stunning natural terrain, its mountainous peaks drawing tourists in from around the world. And the Observation Tower or “Pin” allows visitors to gaze across the local surroundings with 360° views. Three glass elevators transport users to the summit from which they can descend while taking in the panoramic views either to the central level where glass elevators will take them back to the base or further down to the lowest level of the spherical volume where they will encounter the retail and restaurant facilities. Brian Stowell of developers Novawest said of the project: “This is the right place and the right time for a signature project for downtown Phoenix and we knew the design needed to be something extraordinary. BIG has delivered something exceptional, blending form and function in a way that will change the local skyline forever and will give visitors a once-in-a-lifetime experience.” And meanwhile be sure to check Top 20 Tallest Buildings in The World.
