Property Description

Set in the beautiful coastal town of Belfast, this thoughtfully designed, one-of-a-kind 3-4 bedroom, 3.5 bath home blends striking architecture with sustainable, net-zero living. Built for efficiency, durability, and year-round comfort, it offers a rare combination of innovation and livability. Inside, the home features a spacious, flexible layout highlighted by a remarkable 50' x 15' heated sunroom along the south side--an inviting, light-filled space that naturally warms the home in winter while remaining comfortable in summer. Open living areas provide a seamless flow for everyday living and entertaining. The commercial-ready kitchen offers exceptional functionality for serious cooking or potential business use. A large family room with mini kitchen and access to a covered porch creates an ideal gathering space for indoor-outdoor living. Adding to the home's character are several ''secret'' rooms hidden behind custom bookcases. Designed for long-term performance, the home includes an arctic slab foundation for temperature stability, closed-cell insulation, and strategic orientation to maximize seasonal sunlight. Redundant systems--including heat pumps, a propane Generac generator, and a wood stove--add efficiency and peace of mind. A 25kW solar array powers the home, often resulting in minimal to no utility bills. The roof design enhances efficiency with reflective materials for summer cooling and snow retention for winter insulation. Outdoors, enjoy a large fenced backyard and trails through the wooded portion of the lot. A 2-car attached garage adds convenience. All just walking distance from the Belfast waterfront downtown. (Note: This property has a 3BR septic design.)
