Behind the historic gates of Llewellyn Park, America's first planned gated community, this four-acre estate offers a rare blend of architectural legacy, privacy, and thoughtful modernization, now reintroduced at a compelling new price. The main residence has been carefully renovated to honor its early-20th-century craftsmanship while allowing select bedroom and bath spaces to remain opportunities for a purchaser's own design vision. A separate, income-producing carriage house provides valuable flexibility and generates approximately $43,000 annually, with an existing lease through 10/31/27. Set within a storied, park-like enclave minutes from Montclair's dining, culture, and direct NYC access, this is a once-in-a-generation offering for those seeking scale, character, and long-term value in a setting that feels both established and enduring.
