This home just hits every note. Known as The French House after the shipping and whaling magnate who built it c. 1830, the stunning renovation preserves its historic soul. Seriously, who wouldn’t want to live here? Thrilled for our buyers (and truthfully a little jealous!) Sag Harbor’s about to gain some friendly new neighbors.
