Welcome to 1190 Old Mill Road, a comfortable and casual home set on one acre along historic Old Mill Road. The property offers a true "place in the country" feel, while remaining just minutes from Everett Elementary School, the tollway, shopping and downtown Lake Forest - an exceptionally convenient location for everyday living. Originally built in 1928, the home underwent a thoughtful and seamless expansion in 1996, fashioned after Nantucket Shingle Style architecture, adding an additional 3,600 square feet. The result is a warm, welcoming and spacious residence with purposeful living spaces throughout. Nine-foot ceilings span the first floor, enhancing the open and airy feel. An expansive front porch tranquilly welcomes you home, while a screened porch provides a relaxing retreat overlooking the rear yard and patio. Inside, a true great room serves as the heart of the home - ideal for gathering family and friends. Additional first floor living spaces include a den, two private offices (or optional bedrooms) with access to a full bath, and a convenient first floor laundry room (that does double duty as a wet bar!). The second floor features a generous primary suite with a private bath. Three additional spacious bedrooms with generous closets complete the level - one with an en-suite bath and two sharing a large hall bath. The finished third floor adds a fun and unique space, complete with a golf practice range with launch monitor. A large, finished walk-out basement provides even more flexible living and recreation space, along with tremendous workshop and storage space. Having 400 AMP electrical service, the interior is heated and cooled with four independent HVAC systems and WiFi thermostats providing true zoned environmental control. Outside, the fully fenced rear yard includes automatic gates for easy access, which also provides safe and secure containment of any furry four-legged family members! Completing the property is a three-car detached garage, fully heated and cooled for year-round comfort.
