Naperville mansion sells at auction for $8.07M

A five-bedroom, 9,299-square-foot French Provincial-style mansion in downtown Naperville sold Monday for $8.07 million, setting a new DuPage County residential sales record.

The mansion, on West Van Buren Avenue, first was listed in September 2021 for $14.99 million, which also was a DuPage County residential listing record that remains to this day. The mansion was built in 2018 by Donald Brooks, who had been the owner of McCrone Associates in Westmont, and his wife, Jane. After Donald Brooks died in February 2021, Jane Brooks placed the mansion for sale seven months later.

The mansion was taken off the market last year and relisted in February at $12.75 million. It then underwent a price cut to $8.2 million in August. In recent months, real estate agents had suggested uses for the property other than solely as a single-family home.

According to listing information, the mansion underwent an auction on Oct. 16.

Designed by Charles Cook Architectural Design Studio, the mansion has six full bathrooms, three half bathrooms, three fireplaces, limestone and white oak floors, cathedral ceilings, skylights, hand-hewn white oak beams and an on-site studio. The mansion sits on a one-acre property.

The mansion is assessed at 9,299 square feet in size. Real estate listing information states that it has a total of 13,170 square feet of finished space.

Listing agent Katie Minott of @properties Christie’s International Real Estate told Elite Street that the buyer plans to use the mansion as a single-family home.

“It’s truly a special property,” she said. “It’s like walking into a brand-new home. It cost $15 million to acquire the land, build the home and landscape it. So it was a great opportunity. Plus, the location was prime.”

The mansion had a $106,934 property tax bill in the 2022 tax year

Public records do not yet identify the buyers.

DuPage County’s previous record residential sale price was in 2003, when then-Chicago White Sox slugger Frank Thomas sold his 41-room mansion in Oak Brook for $7.95 million.
