Looking for a home that is so energy efficient and self sufficient, that total heating, cooling, water, sewer, and electric costs are less than $700 per year? Then check out this amazing 'Net Zero' home in Windham, Maine. This 3 bedroom, 2.5 bath home was designed & built by MGM Builders to be as comfortable as it is efficient. It features thoughtful, high-end finishes, like granite countertops, farmhouse style sink, and center island in the kitchen. The master bedroom offers a private bath, and a walk-in closet with built-in shelving. The flooring is all hardwood in the bedrooms, living, dining, and common areas, with ceramic tile in the kitchen and baths. Other notable features are the recessed LED lighting, and the extra wide staircase leading up to the second floor. The laundry area is located in the half bath just off of the mudroom, and offers a large workspace over the machines. The heart of this home is it's Geothermal Heating and Cooling System, which is fed by a 550' deep drilled well. The roof mounted solar panels are 100% owned, and operate on a 'Bank' system with CMP, and is fully transferable to the new owner. This means in the summer, the home produces more electricity than it can use, and the extra electricity is sent to the local power company where it is credited to the virtual 'Bank' that the home draws on in the winter, when the panels do not produce enough electricity on their own. The air in the home is circulated through a humidity controlled filtration system that changes all the air in the house every 3 hours, a dream come true for those with allergies! This home sits on a 1.29 acre lot, and is perfectly oriented to maximize it's solar array. The backyard is open and level, and can be enjoyed from the maintenance free deck. In the front, is a fenced in garden for the aspiring backyard farmer. This is truly one of the most amazing, comfortable, and self-sufficient homes in Maine, and will no doubt bring many years of joy to it's next owner
