A rare opportunity to acquire a historic 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 protege 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.
