Until the store closed in 2013, it was the only Kmart in Waukegan. Here's what it looked like before the redevelopment:
The building is now the home of Cristo Rey St. Martin College Prep, which serves nearly 400 low-income, mostly minority students.
Cristo Rey is a national network of 32 schools. The one in Waukegan (before it moved into the former Kmart) opened in 2004 and has a 98% college-enrollment rate.
The empty store was challenging to convert, because the firm wanted to keep to a relatively low budget of $10 million, Moreno told Business Insider.
Cristo Rey's principal, Mike Odiotti, had the idea to move the school into the former Kmart.
He called Moreno from his car one afternoon. "On my way to school, I always drive by this empty Kmart," Odiotti told him.
While the building measures 100,000 square feet, JGMA's renovation spans just 60,000 square feet. That way, the school can expand in the future.
One of the firm's main goals was to "humanize" the building, which featured 22-foot-tall ceilings and no exterior windows (except for the front doors).
"What big-box stores lack are daylight. They're often really Brutalist and tall, with concrete walls that have no sense of human scale whatsoever," Moreno said.
The team installed windows, skylights, and floor-to-ceiling glass curtain walls that look out to a wetland. Natural light now floods the space.
The classroom walls facing the corridor are also transparent, so that passersby can see lessons taking place inside.
Before, Cristo Rey was housed inside a former Catholic chapel, which was "falling apart," according to Moreno.
This isn't the first school JGMA has designed. In 2011 in Chicago, the firm completed UNO Soccer Academy, a charter elementary school with a shiny steel facade.
This also isn't the first abandoned retail store to turn into a school. Austin Community College in Texas turned a dead JCPenney store into a new facility in 2014.

Cristo Rey schools in other cities have similar plans.
Partially inspired by the Waukegan project, Cristo Rey Jesuit High School in Milwaukee will move into a vacant grocery store. Philadelphia's Cristo Rey school will also convert an abandoned tricycle factory into a new facility.
