Step right into 1907 with this iconic West Dundee landmark - The Mansion at 305 Oregon Ave - a Tudor Revival masterpiece built for Illinois Iron & Bolt president John F. Fierke and still wrapped in its original ornamental iron fence handcrafted by the very company that built Dundee's industrial legacy. This historic estate has lived many lives: elegant private residence, beloved bed & breakfast, wedding venue, extended-stay host, and now a flexible multi-unit income property with endless potential. Behind its storied brick, limestone, and half-timbered facade sits nearly 9,000 sq ft of extraordinary period craftsmanship. Inside you'll find 36 stained-glass windows, quartersawn white-oak floors and trim, antique light fixtures, extensive built-ins (including a stately grandfather clock), and an antique clay tile roof. The grand Parlor showcases a sweeping staircase and exquisite millwork. The expansive Front room offers a fireplace, custom stained-glass cabinetry, and two sets of pocket doors. Enjoy the charm of the Library, the unique octagonal Morning room, and the Formal Dining room featuring Mahogany built-ins, a buffet, and original China cabinets. A true Butler's Pantry with full wall-to-wall built-ins connects directly to the kitchen for authentic early-20th-century function. The main house offers a total of 8 bedrooms, 7 full baths, and 2 half baths (including the 4 extended-stay units - 3 on the main level that share a bath and one in the 3rd floor finished attic space with private bath). The former coach house has been transformed into three apartments. Apt A - Ground Level Apartment with 2 bedrooms; Apt B - Second Level Apartment - 2 bedroom/1.1-bath, and 1-bedroom/1-bath; and Apt C - 1 bedroom/1 Bath Main level apartment. This flexible zoning has created multiple income streams and operational versatility. Zoned R-B (Residential-Business), this property practically shouts for creativity: continue operating as an income-producing rental, live onsite while tenants help with expenses, re-establish a boutique inn or B&B, or pursue an entirely new business concept. Located within a TIF district, the property may also be eligible for financial incentives to support your vision. Set on over 0.8 acres and walking distance to downtown West Dundee, you're close to local restaurants, shops, the Fox River, and the bike trail. Rich in history, loaded with architectural detail, and brimming with opportunity, The Mansion is your chance to own one of West Dundee's most iconic and adaptable estate properties.
