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 Ardea consists of 30 floors including an adjacent five-story building. The tower will have 323 units, 380 underground parking spaces and over 16,000 sq ft (1,500 m2) 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.[4] Upon final review, this building is anticipated to receive LEED Gold status in the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) program.

Pricing and occupancyEdit

As the housing market slowed in 2008, nearly 3,000 luxury condos were for sale. In October 2008, 50 of the 323 residences in the Ardea had been leased.[5] In March 2009, prices for a 750 sq ft (70 m2) 1 bedroom started at US$1350 per month and 2-bed-1-bath units were priced between US$2,260 and US$2,650 per month.[6]
