Mountainside Maine Retreat. Set on approximately 21 private acres, this distinctive three-residence property offers an exceptional combination of space, privacy, and flexibility in a beautiful Midcoast Maine setting. Fully powered by a private solar energy system, the property provides year-round electricity to all three residences and supporting structures. At the heart of the property is the main residence, featuring 3 bedrooms, 3 full baths, and a first-floor half bath with laundry. Soaring cathedral ceilings and a dramatic wall of windows overlook the private pond, while wood floors, a chef's pantry, library, fireplace, woodstove, and cupola with spectacular 360-degree views add character throughout. Outside, a stone patio with a wood-fired masonry pizza oven creates an inviting outdoor gathering space. An impressive three-story barn offers vehicle access, a bath, and abundant room for equipment, hobbies, storage, or workshop use. Privately situated in the woods with its own separate driveway, the post-and-beam guest cottage features an open living room, eat-in kitchenette, and half bath on the first floor. A spiral staircase leads to two bedrooms, a sleeping loft, and a full bath with a classic clawfoot tub. A third residence provides even more versatility, offering 3 bedrooms, 2 full baths, and a detached two-car garage. Surrounded by approximately 21 acres of woods and natural landscape, the property offers privacy and room to enjoy the outdoors while bringing together three separate residences in one unique offering. Designed for comfortable year-round living and powered entirely by solar energy, it presents a rare opportunity for a private compound, retreat, multi-residence property, or distinctive Maine getaway.
