9 & 10 Spruce Needle LaneBlue Hill, ME 04614Price: $575,000

Location, Location, Location. Tucked just off the coveted East Blue Hill Road in Blue Hill, this exceptional passive-solar residence (#9) and artist studio (#10) is a rare blend of sustainability, serenity, and convenience. Set in a quintessential Maine landscape of mature spruce, fir, and pine with moss-covered granite outcroppings, this property feels worlds away-yet it's only 1.5 miles from downtown Blue Hill, half a mile from the Kollegewidgwok Yacht Club (KYC), and moments to the walking trails along Peter's Brook at Penny's Preserve. Coastal charm, year-round community, and easy access to Acadia National Park and Bar Harbor complete the setting. The home itself is a truly distinctive and environmentally conscious design, built using a convective ''envelope'' system-an innovative double-structure with an air gap that naturally regulates temperature. In winter, sunlight pours into the generous south-facing greenhouse, warming the interior living spaces. In summer, an air chimney releases rising warm air while drawing in cooler air from the shaded north side of the home. The result is a comfortable, energy-efficient living environment that harmonizes beautifully with its surroundings. Inside, the open-concept kitchen and dining area forms the heart of the home. Thoughtful architectural details-including varied floor levels, stained-glass windows, and a walk-in shower with handmade tile accents-add character throughout. Heat pumps, along with a woodstove, provide auxiliary heating and cooling, as needed. Bedroom, bathroom, and square footage totals in the listing reflect both structures combined. The envelope house is 1,730± square feet with 5 bedrooms and 1.5 baths. The studio is 430± square feet and features a full bath and 3 potential bedrooms-ideal for guests, creative pursuits, or additional living space. Other features include a shed, gardens, a surveyed lot, and a propane standby generator.
