Property Overview

Designed by renowned architect Pietro Belluschi and constructed between 1946 and 1948, Commonwealth is recognized as one of the first glass box, mid-century design towers ever built. Since its creative repositioning beginning in 2008, the building has become one of the dominant locations for Portland’s technology, advertising, media and information tenants.

More than $13.6 million was invested in tenant improvements, shared amenities and capital expenditures in recent years, allowing  Commonwealth to offer a best-in-class tenant experience. Amenities include a roof top deck, building conference room, tenant lounge, bicycle storage, a fitness center and locker rooms. The building fronts the Sixth Avenue transit mall providing tenants with convenient access to mass transit.

The property is among the oldest buildings in Portland to be awarded LEED-EB Gold by the U.S. Green Building Council.
