Twelve west, High-rise building in downtown Portland, Oregon, United States
Twelve West is a 22-floor mixed-use building in downtown Portland, Oregon, with retail space, a lobby and garage access on the ground floor, offices on floors 2 to 5, and apartments above. ZGF Architects LLP, the firm that designed the building, has its headquarters in those office floors.
Twelve West was designed and built under the names "12W" and "ZGF Tower". Initial plans called for 31 floors and a hotel, but the hotel company withdrew and the scheme was revised to 22 floors. A naming contest in July 2009 produced the current name. ZGF Architects LLP, the building's architect, occupies floors 2–5 as its headquarters.
The building's name was chosen in a July 2009 contest, replacing the design-phase labels "12W" and "ZGF Tower". Its ground floor holds retail space, the lobby and garage access, while floors 2 to 5 house the offices of ZGF Architects LLP, the firm that designed the tower.
The building occupies a site at 430 SW 13th Avenue in downtown Portland. The ground floor holds the retail space, the lobby and the garage access, while floors 2 to 5 are offices and the upper floors are apartments. Visitors can walk around the exterior to see the rooftop turbines.
Four wind turbines sit on the rooftop and produce power for the building's energy needs throughout the year. These visible turbines represent an unusual feature for a downtown high-rise in the region.
