The 'House Of The Day After Tomorrow' In Lake Forest Has Been Remodeled Into A Vast Mansion

LAKE FOREST, IL — There were a variety of futuristic sights on display during the 1933 World's Fair in Chicago. One of them was the "Houses of Tomorrow" exhibition, which demonstrated examples of what architects thought the homes of the future would look like. One of them, now known simply as the "House of Tomorrow," sits at the Indiana Dunes, where Indiana Landmarks is seeking to restore it. It was ahead of its time, with glass and steel walls, central air conditioning and passive solar heating. It also had a couple of features that didn't quite catch on, like an airplane hanger and dodecagon shape.

After seeing the exhibition, Irma Cahn née Kuppenheimer, heiress to a clothing manufacturing fortune, contacted the architect, the modernist master George F. Keck, to build her a summer home on 30 acres in Lake Forest. According to the Lake Forest and Lake Bluff Historical Society, she told Keck she wanted one better than the house of tomorrow: 'The House of the Day After Tomorrow'

The house was expanded and redesigned in the 1990's. A second story was added and the home is now nearly 15,500 square feet, with seven bedrooms and nine full bathrooms. The first floor now features marble floors, columns and an indoor waterfall.

The home sits on a five-acre wooded lot adjacent to a park. It's got an in-ground pool, spa, hot tub, patio bar and a five-car heated garage. The lower level has a second kitchen, a bar, an exercise room and a guest bedroom.

The home's current owners, Rajul and Dr. Gopal Bhalala bought the property in 2004 for $4.9 million, according to property records. They first listed the home in 2013 for just under $5.5 million. Last week, it was listed again at $4.85 million.

A 2013 video produced by Chicago Magazine provides a tour around the site.
