Description: Perched high above Honolulu on Round Top Drive, this extraordinary estate spans six parcels totaling 76,970 square feet and offers a rare combination of privacy, history, and unrivaled panoramic views stretching from Diamond Head and the Pacific Ocean across the Honolulu skyline to Manoa Valley and the surrounding mountains. Held by the same family for nearly a century, the property is anchored by a 5-bedroom, 3-bath residence with a total of 3,360 square feet of interior living space. Originally built in 1937 and later expanded with an addition designed by renowned architect Alfred Preis, the home retains distinctive midcentury features and character throughout. A separate downstairs living area with its own kitchenette offers flexibility for extended family, guests, or rental use. Decades of thoughtful landscaping have created lush, established grounds with mature koa and fruit trees and a remarkable sense of privacy. The estate also presents significant potential for additional residences, a multi-generational compound, or a thoughtful reimagining, subject to buyer due diligence. A rare opportunity to own a legacy property of this scale, setting, and character in Honolulu.

Description: A rare opportunity to acquire an incredible Honolulu estate. Built in 1908 by Alfred Castle, this remarkable 13+ acre Tantalus property has been held by just four distinguished families, Castle, McCandless-Marks, Dillingham lineages, and the estate of Juan Hamilton—renowned artist and protégé of Georgia O’Keeffe. A stately drive welcomes you with eucalyptus trees where expansive lawns evoke the elegance of a bygone era and invite grand outdoor gatherings. Panoramic views from Diamond Head to Haleiwa showcase striking sunsets over the Pacific. Fragrant puakenikeni, jasmine and white ginger bloom amid a landscape of moss rock walls, brick pathways, and wooded trails. The buildings are rich with historic details and distinctive architectural finishes. A 60,000-gallon water catchment system underscores the estate’s blend of heritage and stewardship. More than a residence, this is a landmark property awaiting its next chapter—a chance to reimagine one of Honolulu’s great estates. For those drawn to the intersection of history, nature and place, this extraordinary offering represents far more than real estate. It is a legacy to inherit, shape, and preserve for generations to come.
