A rare opportunity in Montclair, this residence offers an expansive triple-parcel, park-like setting with remarkable flexibility for today's homeowner, investor, or developer. The main house sits on a third of an acre, flanked on both sides by vacant parcels that bring the total contiguous land to just over one-and-a-quarter acres. Keep the vacant lots as-is for open space, develop one or both, or build something multigenerational. A long, flat, and freshly paved driveway and two parking areas give way to a gated entry to the landscaped front yard of the residence. Outdoor areas for sitting, dining, and entertaining set the stage on your stroll to the front door. Inside, a soaring great room greets you, its scale and light setting the tone for the rest of the home. The space accommodates multiple furniture arrangements, with ample storage and direct outdoor access, with a powder room nearby. From here, the layout flows to the chef's kitchen with an oversized island and open connection to the dining room, the kind of configuration that makes hosting feel effortless. A separate wing on this level holds two bedrooms, a full hall bath, and a laundry room. The primary suite occupies its own quiet corner of the main floor, but just close enough to feel connected. A sitting alcove, verdant tree views, and a spa bath with a glass-walled shower, soaking tub, dual vanity, and walk-in closet make this bedroom feel special. Downstairs, a second primary suite provides genuine privacy for guests, in-laws, or older kids, alongside a media lounge with easy conversion to a fifth bedroom, a powder room, and direct access to the flat, irrigated, grassy yard for kicking a soccer ball or relaxing on a picnic blanket. Entertainers will love the multiple areas for guests to enjoy the dappled light of the afternoon or the warm summer evenings in this special enclave. Grillmasters will love the outdoor area near the kitchen for weeknight or special occasion barbecuing. Two flanking, vacant parcels are available separately or in combination with the house. The lower left parcel has city skyline views, a shared driveway, and architectural plans ready to transfer-a meaningful head start in its development. The larger, upper right parcel offers privacy, scale, and its own development potential.  Thornhill Elementary, Montclair Village, Highway 13, and Highway 580 are nearby. The Aspinwall Compound is ready for its next chapter.
