Starved for space and craving country living, yet still wanting to remain close to everyday conveniences and the city? This truly rare offering delivers the best of both worlds. Custom built and thoughtfully expanded by its long-term owner, this impressive two-story residence sits on an "A"-rated 2.5-acre parcel in low-tax, unincorporated Orland Park, right along the edge of scenic forest preserves. The home features a 3-car garage configuration, including a heated 2-car garage plus a separate 1-car garage, along with an exceptional 30x30 OUTBUILDING divided into a 2.5-car garage and a spacious workshop, complete with a walk-up attic/loft-ideal for hobbies, storage, or business use. An oversized shed located next to it adds even more utility. Inside the house, you'll find generous main living quarters offering four bedrooms, three full baths, and two half baths, along with a private RELATED-LIVING APARTMENT wing-perfect for extended family, in-law living, or a flexible lifestyle setup such as a home office or guest suite. The main living area welcomes you with a gracious foyer that flows into a spacious living room and continues into the country-style kitchen, remodeled approximately 12 years ago. The kitchen boasts abundant alder wood cabinetry, a center island with breakfast bar, stainless steel appliances, two pantries, and a large dining area. Adjacent is a sunken family room with convenient access to the main-level laundry room, complete with extensive storage cabinetry and washer and dryer. A door from the kitchen leads to a massive, recently painted, multi-level deck with gazebo, overlooking a magnificent, one-of-a-kind backyard that offers privacy, space, and endless possibilities. Upstairs, all bedrooms are generously sized, highlighted by an exceptional XXL primary suite featuring soaring vaulted ceilings, an abundance of windows, a floor-to-ceiling fireplace, two walk-in closets, and a private bath with classic finishes, dual sinks, a relaxing bubbler soaking tub, and a fully tiled walk-in shower. The related-living apartment includes a second kitchen open to a dining area with access to a private patio, one bedroom, one full bathroom, and a sizeable second living room with vaulted ceilings. It also offers its own laundry area with stackable washer and dryer and a separate HVAC system for added independence and comfort. The finished basement provides even more space for indoor entertaining and recreation. The property is serviced by city water and sewer, while the ENTIRE LOT is equipped with a sprinkler system powered by well water. Roofs on the house, outbuilding, and shed were all replaced in 2024. Opportunities like this are exceedingly rare-especially a property of this size, versatility, and setting that has remained in the same family since it was built. A true estate-style offering combining space, privacy, functionality, and location-homes like this simply don't come along often. Schedule your viewing before this classic rare gem is gone!
