Adellco LLC is planning to build a residential condo tower of about 30 stories on the northwest corner of 28th Street and the Avenue of the Americas.

The site, which extends about half way to 29th Street, is now vacant.

According to Ann Eber, a vice president of Adellco, Costas Kondylis is the architect. She told CityRealty.com that plans were preliminary and that further details were not yet available.

The building will probably have the address of 815 Avenue of the Americas.

Adellco is run by Matthew Adell, who developed the 37-story Capitol at 55 West 26th Street in 2001 and the 36-story Ashton at 800 Sixth Avenue in 2004.
