Phoenix-based developer Novawest wanted a new signature project for the city’s downtown, an observation tower from which to admire the far-off mountain ranges and dramatic Southwestern sunsets, so Bjarke Ingels proposed to scoop out the spiraled negative-space of New York’s Guggenheim Museum rotunda and plant it 420 feet above downtown Phoenix. Ingels’ “Pin,” a 70,000 square foot observation tower is elegant in its simple form, a ball on a stick, indeed evoking some far away Gulliver on a real-life version of Google maps finding his way to the Sun Belt. In another light, Phoenicians could ostensibly see a larger-than-life Chupa Chup or an upended mascara brush, but that’s the beauty of pure form, right?

Visitors will be able to ride one of three glass elevators up the reinforced concrete core to the top of the Pin’s observation spiral, where flexible exhibition, retail, and recreation spaces will showcase panoramic views of the surrounding region and descend, round and round, to a restaurant in the lower portions of the sphere.

“Like the monsoons, the haboobs, and the mountains of the surrounding Arizonian landscape, the Pin becomes a point of reference and a mechanism to set the landscape in motion through the movement of the spectator.” Bjarke Ingels, principal at BIG, said in a statement. “Like the Guggenheim Museum of New York offers visitors a unique art experience descending around its central void, the motion at the Pin is turned inside-out allowing visitors to contemplate the surrounding city and landscape of Phoenix. Like a heavenly body hovering above the city, the Pin will allow visitors to descend from pole to pole in a dynamic three dimensional experience seemingly suspended in midair.”
