Situated on the coveted tree-lined streets of Portsmouth's Little Harbor District, 183 Miller Avenue is a distinguished 1862 residence that beautifully reflects the architectural heritage and timeless character for which the city is so admired. High ceilings, abundant natural light, a timeless staircase, and exquisite original millwork create an atmosphere of warmth and understated elegance, while the open floor plan offers an effortless flow for everyday living and entertaining. Beautifully preserved while incorporating modern comforts, the home offers an ideal balance of historic style and contemporary living. A first floor primary suite, completed in 2026, blends with the original architecture while providing the conveniences today's buyers seek. Vaulted ceilings with exposed beams and skylights, a charming private porch, its own laundry, and a beautifully designed bath create a flexible space ideal as a first-floor bedroom, guest quarters, home office, or multigenerational retreat. Outside, a welcoming front porch, spacious yard, two-car garage, and driveway provide amenities rarely found this close to downtown. Just beyond the front door, mornings begin beneath the Little Harbor neighborhood's tree-lined streets, afternoons invite a stroll along the waterfront, and evenings are spent enjoying Prescott Park, downtown restaurants, boutiques, and Portsmouth's vibrant arts and cultural scene. Rich in history, beautifully updated, and perfectly positioned, 183 Miller Avenue offers not simply an exceptional home, but an extraordinary Portsmouth lifestyle.
