About This Home

54-333 Union Mill Rd

Step into the timeless elegance of the Union Mill Plantation Manager’s Estate, a beautifully restored 1886 historic residence set on 1.34 acres of manicured, park-like grounds. Surrounded by century-old cypress trees, royal palms, and lush gardens, this stately home is one of North Kohala’s most significant architectural treasures. Offering 5 bedrooms, 3.5 baths, and over 4,000 sq ft of living space, the home features classic plantation-era craftsmanship, soaring ceilings, wood details, and gracious rooms oriented toward serene garden views. Listed on the State Historic Register, the property can potentially benefit from exceptionally low real property taxes (approximately $200/year)—a rare advantage for an estate of this scale and history, Buyer to do their own due diligence. The compound spans two TMKs, so there is an option to build another residence and also includes multiple historic structures: the original caretaker’s cottage, a garage/workshop, and a separate storage building. Zoned RS-15, the property offers space, privacy, and a timeless sense of place. Modern conveniences blend seamlessly with its historic charm: county water, overhead power, cable TV, satellite service, fiber-optic internet, and wireless options are all available. Located on quiet, private Union Mill Road, the estate is ideally positioned between Hawi and Kapaʻau—just minutes to markets, restaurants, schools, and all the beloved amenities of North Kohala. Rarely does a home of this caliber become available. This is an opportunity to own a beautifully preserved piece of Hawaiʻi’s sugar-era history—an iconic plantation estate that is truly one-of-a-kind.
