the capital city of arizona, USA will be receiving a new addition to its city skyline in the form of a large 70,000 square foot observation tower
designed by BIG architects. a project commission by local developer novawest, the observatory is set to be a destination for tourists and city citizens alike,
to enjoy the ‘valley of the sun’.

the tall slender reinforced concrete structure, whose principle feature is a large spiralling sphere at its top, stands as a metaphorical representation of a pin -
as if marking a point on a map. the winding area can be reached via three glass elevators, connecting the base with its summit where panoramic views of the city
and its surrounding landscape can be taken in. walking down the spiraling promenade, one is able to experience all of the tower’s programs which include
flexible exhibition, retail and recreational spaces. the separation of these elements do not occur through physical vertical barrier walls,
but rather progressively through the slight sloping and height difference of its pathway, preserving a continuity throughout.

instead of a constant width, the helical walkway begins from zero at the point of arrival, reaching its maximum at the middle,
and shrinking back to zero at the point of departure. once visitors have reached the centre of the sphere, they can either choose to conclude their
trip or continue to the restaurant levels at the lower hemisphere. the motion of navigating around it being much like that of a journey through the centre of a planet,
travelling from north to south. a public plaza will be situated at ground level offering shade, water features and small retail shops with a subterranean queuing area.
the new landmark will serve as a working model of sustainable energy practice, incorporating a blend of solar and other technologies.

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.
‘ – brian stowell, novawest

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. 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
