Built in 1891, the Oregon National Guard Armory building is one of the Northwest’s most significant 19th century buildings, and is listed on the National Register of Historic Places. The 55,000 sqft building reopened on October 1, 2006 as the permanent home for Portland Center Stage with a 600-seat main stage and a 200-seat studio theater.

The Gerding Theater is the first building on the National Register of Historic Places and the first building in Portland to achieve Platinum LEED certification. Green building strategies include the use of a water catchment system. Rainwater from the Armory roof is collected and stored in a 10,000-gallon subterranean cistern, then recirculated for use in both plumbing and artwork. Alternatives to traditional heating, ventilation and air conditioning provide improved indoor air quality and reduce energy bills by an estimated 30 percent. Individually controlled active chilled beams supply overhead heating and cooling, while a raised access floor supplies under-floor ventilation by locating air outlets where needed. Displacement ventilation was used to supply fresh air under the fixed auditorium seating, displacing warmer room air with fresh cool air.
