The Ardea, formerly 3720, is a 30-story 99.06 m (325.0 ft) 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.
