The Oscar B. Balch House is a home in Oak Park, a suburb of Chicago, Illinois, United States.

By 2024, Lotti had spent $800,000 renovating the house, excluding the cost of solar panels, which she planned to install at a later date.

[4] Regardless, the house has a remarkable linear proportion and Wright managed to raise the eyeline with the rows of windows on the home's second floor.

"[5] In the living room the house is anchored by a Roman brick fireplace at its center and there are libraries on either side of two small setback pavilions.

[4] The Oscar Balch House represents Frank Lloyd Wright's defiant return to the streets of Oak Park and to architecture after his absence and concurrent trip to Europe with Mamah Borthwick Cheney.

[4] The house was called "forged of Wright's personal courage and cheeky moral humbridge" by historian Thomas O'Gorman.

[4] O'Gorman concluded it was possible that the Balch House provides a rare glimpse into the subconscious mind of Frank Lloyd Wright.

Its flat roof and horizontal linearity are a continuation of the ideas Wright began to manifest in the Mrs. Thomas H. Gale House in 1909.

[3] The Oscar B. Balch House is listed as a contributing property to the Frank Lloyd Wright-Prairie School of Architecture Historic District.
