Filled with authentic character and offering exceptional living space, this mid-century modern home features a standout second-floor addition, an expansive lower level, and a wonderful Downers Grove location near the BNSF train, Barth Pond, Downers Grove Swim & Racquet Club, and within the Downers Grove North High School attendance area. The second floor is truly special. A spacious family room with a cozy fireplace creates an inviting retreat for relaxing and entertaining. Step directly onto the screened-in porch to catch the breeze, enjoy backyard views, or unwind on a summer evening. This level also features a private primary suite with an en suite bath in authentic mid-century style, creating a comfortable space set apart from the rest of the home. On the main level, a bright living and dining room is filled with natural light from a large picture window overlooking the neighborhood. Three additional bedrooms offer flexible space for family, guests, or a home office, with built-in cabinetry in two providing convenient storage. The updated main-level bath features a walk-in shower. The refreshed mid-century kitchen retains the home's original character while incorporating practical updates, including a new stainless-steel sink, faucet, and refrigerator. Downstairs, approximately 900 additional square feet offers impressive space and possibilities. This massive lower level has been refreshed with new windows and freshly painted ceiling and floor, creating a clean, bright foundation for a recreation room, home gym, workshop, hobby space, or additional storage. Built-in cabinetry and an organized laundry area add even more functionality. Outside, the impressive backyard offers plenty of room to garden, play, entertain, or simply enjoy the outdoors. A heated tandem two-car garage adds another valuable and versatile feature. With 70 years of history, distinctive mid-century details, unusually generous living space, and thoughtful improvements throughout, this is a special opportunity to make a truly unique Downers Grove home your own.
