This custom-built Colonial offers a rare combination of large, sunlit rooms with flexible uses, privacy, and easy access to downtown Durham. Proudly serving the same family for decades, the home has been exceptionally well-maintained and reflects the care, quality, and pride of long-term ownership. Set on an oversized lot in a sidewalk-lined neighborhood, the property provides a peaceful private setting just minutes from schools, downtown Durham, UNH, dining, cultural events, and everyday conveniences. Inside, the home is move-in ready and filled with natural light. Its flexible floor plan has supported a variety of multigenerational living needs, including several home offices, guest rooms, game and exercise areas, and an accessible, single-floor aging-in-place option. The floor plan is classic yet ahead of its time with a great room/kitchen, dual bathroom sinks, an en suite primary bathroom, and a sunroom. Ready to move right in, this property also offers the next owner an opportunity to create spaces tailored to how they live, on their schedule, rather than settling for a cookie-cutter renovation. Outdoor living is a standout feature, with an expansive lawn, screened gazebo, patio, and welcoming front porch. The generous yard offers room to garden, play, entertain, or explore future possibilities such as a pool. The bonus lower/basement level also offers potential for additional finished space, whether for a fitness room, game room, media area, hobbies, workshop, or storage. There is additional storage space in the garage attic and the adjacent shed. With quality construction, an endlessly flexible layout, a private setting, and close proximity to Portsmouth and the Seacoast, this Durham property offers a compelling opportunity to make a well-loved home your own! In addition, an adjacent lot (MLS #5088066) is also available, offering a rare chance to purchase both parcels for added privacy, future flexibility, investment, or an expanded family compound.
