It is one of 15 homes in a development called Bel Vista, designed by local architect Albert Frey.
Known as Bel Vista #2, the house is now listed at $995,000.
Frey created the early modernist architectural typology for which the area is known.
The house is both a local historic landmark and listed on the National Register of Historic Places.
It embodies Albert Frey's indoor-outdoor lifestyle, as it has seven doors in a 1,100 square foot house that is unlike most post-war built houses.
The three-bedroom, one-bathroom house was built in 1946.
Real estate figures show that Hayes bought it in 2015 for $376,000. He then embarked on an extensive renovation.
He notes that the exterior's curved brick walls are original and typical of the area's historic architecture.
The large corner lot has a swimming pool and fire pit in the backyard, surrounded by a corrugated metal fence inspired by Foley.
Of the 15 original houses in Belle Vista, none have been demolished, but several have been altered considerably - to the point of being unrecognisable.
Over the next 75 years they were altered, and more on the outside than on the inside, and at one point all 15 houses were essentially the same.
But Frey flipped them, rotated them, and changed the setbacks. As a result, when you initially drive down the street, they look like 15 different houses.
This is the second house Hayes has restored on the property. He is now working on restoring a third.
Hayes initially listed it for $1.1 million in October. He lowered the price to $1.05 million in November and recently reduced it by another $55,000 to its current price.
Hayes acknowledges that the home's single bathroom is an issue for many potential buyers now.
Due to historical designations and municipal red tape, Hayes said the city would not conditionally approve another bathroom.
The home's next owner will be allowed to use the home as a short-term rental.
Hayes said he knows the perfect buyer is out there - probably someone who doesn't have big renovation dreams.
It needs a buyer who can accept a bathroom and who really likes the house as it is.
