At the heart of historic ’Sconset, where location is everything and legacy is rarely offered, Green Chimneys stands apart as one of Nantucket’s most iconic and enduring estates. Location, legacy, and rarity converge at this extraordinary Main Street property, prominently positioned in the heart of the village just moments from the beach, market, and village center. Offering a rare combination of history, scale, and exceptional in-town grounds, Green Chimneys unites more than two centuries of provenance with beautifully scaled living and entertaining spaces, all enhanced by coveted HDC-approved plans for a pool. A landmark offering of uncommon character and distinction, Green Chimneys stands among the island’s rarest and most compelling ownership opportunities.
