The Ardea

The Ardea, formerly 3720, is a 30-story 99.06 m apartment skyscraper in the South Waterfront district of Portland, Oregon. The building was completed in March 2009, however was turned over in phases allowing occupancy beginning in August 2008. The Ardea was developed by Gerding Edlen, designed by GBD Architects, and constructed by Hoffman Construction. The building was initially designed to be a condominium building but was converted to apartments after the Portland housing and condominium supply outstripped demand. The Ardea joins John Ross Tower as the seventh tallest building in Portland.

The Ardea consists of 30 floors including an adjacent five-story building. The property consists of 323 units, 380 underground parking spaces and over 16000 ft2 of retail space on the ground floor.

The exterior cladding of the building is constructed with a variety of materials including window wall, curtain wall, precast concrete panels, and a metal cladding system. The Ardea received an Excellence in Concrete Award in 2009 for the unique application of precast that runs up the exterior of the building in two vertical bands on both the north and south faces. This building received LEED Gold status in the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) program.
