This exceptional waterfront home on Seven Tree Pond is a dream for lovers of historic New England architecture and the outdoors. Set on more than three acres with 95' of owned frontage, this thoughtfully preserved center-chimney Colonial offers an extraordinary setting for life on the lake, with pond and pastoral views from all three levels of the home. Enjoy swimming, kayaking, or motoring from the dock and sunsets around the lakeside firepit. Part of the Saint George River watershed, Seven Tree Pond connects directly to Round Pond, White Oak Pond, and the Saint George River, giving paddlers and boaters a variety of waters to explore. Across the road, an expansive bog provides a haven for wildlife. Inside, wide-plank pumpkin pine floors, exposed beams, original fireplaces, and warm woodwork blend seamlessly with thoughtful updates. Each room feels like a work of art, from the character-rich formal dining room to the modern chef's kitchen with its cathedral ceiling. The first floor also offers a living room, powder room, and primary suite with renovated marble bath and walk-in closet. The kitchen opens to a spacious deck and patio overlooking the pond. Designed for both gathering and privacy, the second floor features a family room with fireplace, two generous bedrooms with walk-in closets, full bath, and oversized, light-filled laundry room. One bedroom retains an original fireplace with wood-paneled surround. Upstairs, the third floor's exposed beams frame a flexible space for a studio, office, media room, additional bedroom, or creative retreat. Outside, perennial gardens and wildflowers explode with color in season, while the acreage offers room to garden, gather, and enjoy the water. A detached garage and paved driveway complete the setting. Ideal as an artist's retreat or multi-generational compound, with potential to explore an additional lot and home, subject to approval. Just five minutes from Union Common and 20 minutes from Rockland and Camden.
