A seven-bedroom mansion in Naperville that is on the market for $10.5 million went under contract this week. If the 21,709-square-foot mansion sells for more than $8.1 million, it will be the highest recorded sale price for a home in DuPage County history.
Built in 2017 by custom homebuilder Dave Knecht and situated on a 2.51-acre property, the Tudor-style brick and limestone mansion has nine full bathrooms, three half bathrooms, leaded casement windows, eight fireplaces, stone staircases, a custom artisan iron entry door, custom lighting and crown moldings. The mansion’s great room has a floor-to-ceiling stone fireplace and French doors while the kitchen has two islands, quartzite countertops, Kohler fixtures, Sub-Zero and Wolf appliances and a butler’s pantry.
Other features include a hearth room, a library with custom wood built-ins and a custom wood ceiling, and a first-floor primary bedroom suite with a custom turret, a private sitting room, a wet bar, two custom walk-in closets and a bathroom with a Kohler computerized stone walk-in shower, three vanities, heated floors and dual water closets.
The mansion also has a second primary bedroom suite on the second floor, along with an attic on the third level. The lower level’s centerpiece is a custom leather and wood sports bar with leather-finished countertops, a stainless steel bar sink, four beer taps, and Sub-Zero and Fisher & Paykel appliances. The basement also has a movie theater that seats 17 and has custom wool carpeting with heated floors, as well as a fitness room, a private spa and a wine cellar behind iron doors that can hold more than 3,000 bottles.
Outside on the property are a bluestone patio, an outdoor fireplace, an outdoor living room, a gas fire pit, a pool, an infinity spa and a pool house.
