CHICAGO-Christopher T. Carley plans to build a luxury condominium tower that he says would be the tallest skyscraper in the US. Carley's Fordham Co. has commissioned a design by Santiago Calatrava, whose projects include the World Trade Center Transportation Hub in New York City and Milwaukee Art Museum expansion.

The design of the lakefront Fordham Spire, as well as details concerning location, cost and financing, will be unveiled Wednesday morning, says a spokesperson for the developer. However, the unveiling is set for the Museum of Contemporary Art at 220 E. Chicago Ave., and Carley's condominium developments include Fordham Tower, the Pinnacle and 65 E. Goethe, all in the city's Gold Coast neighborhood. Carley is said to have spent three years working on bringing a Calatrava design to Chicago.

At 110 stories and 1,454 feet, the title of the US' tallest building belongs to Sears Tower. Would-be developers have pitched plans for record-breaking buildings Downtown. That includes Donald Trump, who ultimately scaled back his condominium and hotel building under construction at 401 N. Wabash Ave. following the destruction of the World Trade Center. Taipei 101 in Taiwan is currently considered the world's tallest building.
