Twelve West (stylized as twelve | west) is a 22-floor, mixed-use apartment and office building located in downtown Portland, Oregon, United States. The building is home to INDIGO @ twelve | west apartments and ZGF Architects LLP. During design and construction the building was known as “12W” and “ZGF Tower”, but the name changed after a naming contest in July 2009. Initial plans included a hotel and a total of 31 floors, but they were revised after the hotel company withdrew.
