**Multiple Offers Received. Seller to review all offers @ 3pm Wednesday 11/26.** Welcome to a one-of-a-kind modern eco-retreat set on 11.81 secluded acres in the heart of Andover. Custom-built in 2008 with a focus on sustainability, efficiency, and long-term durability, this thoughtfully designed 2-bedroom, 1-bath ranch offers a rare blend of privacy, beauty, and low-impact living. Step inside and immediately feel the sense of volume and light: vaulted ceilings, bamboo flooring, and an airy open layout create a bright, comfortable atmosphere from the moment you enter. The living area is anchored by a wood-burning stove that, paired with the home's passive solar design and owned active solar system, provides exceptional heat with minimal propane use - even in the coldest months. Solar light tubes add soft, natural illumination without the maintenance of skylights. The kitchen flows effortlessly off the main living space, offering generous cabinetry, stainless appliances, and easy access to a versatile utility closet that can function as pantry storage or future first-floor laundry. An oversized bathroom brings in beautiful natural light and features a large walk-in shower. Both bedrooms offer high ceilings and thoughtfully designed storage, with the secondary bedroom featuring a built-in loft bed that maximizes space and adds charm. Downstairs, the full-size, full-height basement is a standout: pristine, wide open, and ready for workshop use or future finishing.
