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.
