Situated between two city parks in Portland’s Pearl District, the Cosmopolitan is the tallest building in the Pearl and tallest all-residential tower in Portland. Site and zoning constraints drove the design of the 340-foot-tall, 28-story point tower, which sits on a full city block. 

A four-story concrete podium conceals three levels of above-grade parking behind residential and retail units. Soil conditions did not permit sub-grade parking. The podium is supported by drilled shafts and topped with shared indoor and outdoor common areas and green roofs. The tower rises at the southwest corner of the building. The structure is composed of concrete flat slabs  with concrete moment frames at the building core. 

The glass curtain wall enveloping the entire building was produced by Benson Industries and is the same product as used on the Freedom Tower in New York City. The sleek cladding gives the impression of a singular form, rather than a separate base and tower. Recessed decks rise in columns in the tower, cleaving it into distinct planes and giving each unit a protected outdoor room from which to enjoy wide views of the City and West Hills.
