Behind the historic gates of Llewellyn Park, America’s first planned gated community, this four-acre estate originally known as The Oakbrook Estate and built for the Colgate Family offers architectural legacy, privacy, and thoughtful modernization at a compelling new price. The main residence has been carefully renovated to honor early-20th-century craftsmanship while select bedroom and bath spaces remain opportunities for a purchaser’s design vision. An attached private apartment with its own entrance offers flexibility for extended stay guests or live-in staff. A separate income-producing carriage house generates approximately $43,000 annually, with lease in place through 10/31/27. The grounds create a true resort setting, anchored by a heated in-ground pool and an extraordinary 3,000 sq ft pool house ready to be completed as a cabana, event space, additional living quarters, golf simulator retreat, or wellness pavilion. Spanning three parcels across four acres and minutes from Montclair’s dining, culture, and direct NYC access, this is a rare opportunity to own scale, history, and future upside within one of the region’s most storied enclaves. Annual property taxes approx. $61,717.
