Set along one of Mount Desert Island's most celebrated stretches of coastline, this private coastal compound combines two year-round residences, deeded dock access, and beautifully maintained grounds. At the heart of the property is Windward, the principal residence, where extensive improvements have created a home equally suited for everyday living and large-scale entertaining. Multiple gathering spaces, three fireplaces, a chef's kitchen, expansive covered porches, and a substantial granite terrace with sweeping views across Western Way encompassing the Cranberry Isles and the distant mountains of MDI provide a seamless connection between indoor and outdoor living. Offering five bedrooms and four-and-one-half baths, the residence features a spacious main-level primary suite complemented by four additional bedrooms on the second floor, including a generously sized ensuite bedroom that offers additional flexibility. Complementing the main home is Hard Aground, a fully independent guest residence offering four bedrooms, two baths, a fireplace, a flexible layout that includes two bedrooms and a full bath on the main level, and a deck with views across the lawn to the water beyond. Additional enhancements throughout the property include a dedicated fitness studio, media room, updated systems, and numerous interior and exterior upgrades. The result is a turnkey coastal estate equally suited as a primary residence or seasonal retreat. Beyond the residences, the property features curated gardens, mature landscaping, an apple orchard, deer fencing, and a gated entrance. Deeded access to a shared dock provides an opportunity to enjoy the surrounding waters and islands that make this region one of Maine's most sought-after destinations. Located just minutes from Southwest Harbor & Acadia National Park, this exceptional estate offers access to hiking, boating, dining, & outdoor recreation. A remarkable offering that brings together natural beauty, privacy, & modern comfort.
