The top of Chicago's skyline is ready for a makeover after remaining virtually unchanged in recent decades.

JDL Development recently unveiled plans to build a supertall residential tower across the street from Holy Name Cathedral.

If that project is approved by the city, three of Chicago's 10 tallest skyscrapers could be knocked from the list in the next five years.

The JDL Development project, called One Chicago Square, would bring as many as 900-plus luxury apartments and condominiums to two towers atop a nine-story retail base. The taller of two proposed towers would be 76 stories.

At 1,011 feet, it would be the city's sixth-tallest building.

One Chicago Square would join two other top-10 high-rises already under construction: the Vista Tower condo and hotel tower at Wacker Drive and the Chicago River, which will be the city's third-tallest; and One Grant Park, along the southern end of its namesake park, which will rank 10th.

Set to be displaced from the top 10 are 900 N. Michigan Ave., Chase Tower and Water Tower Place.

Because of a wave of mega-developments in Chicago, changes at the top may not end there.

Related Midwest has yet to unveil its plans for the vacant site where the Chicago Spire -- a 2,000-foot-tall, Santiago Calatrava-designed tower that would have been tops in the Western Hemisphere -- was once planned by another developer. That prominent parcel, along the river and Lake Shore Drive, is likely to become home to a skyline-altering residential building.

Also, the third and final phase of the ongoing Wolf Point development at Orleans Street and the river is expected to include a tower more than 900 feet tall.
