Introducing one of the final opportunities to create a legacy estate within the exclusive Montage Healdsburg residential collection. Arguably the best homesite within the enclave, Estate Homesite 15 encompasses approximately 16,743 square feet, making it one of the largest homesites within the coveted Estate Collection. Nestled among mature oak woodlands and thoughtfully positioned to maximize privacy, this exceptional property offers an extraordinary setting for a custom Wine Country retreat. This lot is contiguous to Estate Homesite 16 (MLS #326061006), and when acquired together, the combined area presents a singular opportunity to build an unparalleled legacy residence. Originally designated for the stunning Estate Home E architectural concept, the homesite was envisioned to accommodate an approximately 4,362 square foot contemporary residence featuring four bedrooms plus a den, four-and-one-half baths, a dramatic detached primary suite, expansive great room, private pool and spa, generous outdoor entertaining spaces, and seamless indoor-outdoor living designed specifically to embrace the Sonoma lifestyle. Ownership includes privileged access to the world-renowned amenities of Montage Healdsburg, including Spa Montage, Hazel Hill restaurant, resort pools, fitness center, concierge services, miles of scenic walking trails, and the legendary hospitality synonymous with the Montage brand. Just minutes from the historic Healdsburg Plaza and surrounded by award-winning wineries, Michelin-starred dining, and endless outdoor recreation, Estate Homesite 15 represents one of the last opportunities to create a custom legacy residence within one of Northern California's most prestigious luxury resort communities.
