Its floor area is 1674708sqft.ArchitectureThe building was designed by noted architects John Burgee & Philip Johnson, partners influential in postmodern architecture. Ally Detroit Center was constructed from 1991 to 1993. It houses numerous tenants, including many prominent Detroit law firms and PricewaterhouseCoopers. In addition to retail, the building also contains a restaurant and a gym.The building is famous for its postmodern architectural design topped with Flemish-inspired neo-gothic spires which blend architecturally with the city's historic skyline. It is constructed mainly of granite. Sometimes called a "twin gothic structure", for its pairs of spires, it is oriented North-South and East-West (as named on a plaque along the Windsor waterfront park). Ally Detroit Center won an Award of Excellence for its design in 1996. Ally Detroit Center replicas have become a souvenir item along with those of other Detroit skyscrapers.
