    Discover the timeless charm of Atlantic Heights! Often described as “quaint” and “charming,” this historic World War I neighborhood was designed in the English Garden Style, with tree-lined streets, sidewalks, a community park, and handmade pocket gardens that bring color and life through every season. This classic 3-bedroom home blends historic character with modern updates and is ideally located 1.5 miles to downtown Portsmouth, and just minutes from Newington shopping and Routes 95 & 16. Inside, beautiful hardwood floors flow throughout a thoughtful layout. The light-filled kitchen features granite countertops and overlooks a sweet, fully fenced backyard. An enclosed porch doubles as a spacious mudroom—perfect for coats, bikes, and outdoor gear. Upstairs are three bedrooms, a full bath, linen storage, and an attic with great ceiling height and pull-down access (unfinished but ideal for future use). The full basement includes laundry and additional storage. Enjoy a generously sized fenced yard with a shed and patio, plus one deeded off-street parking space & abundant on-street parking. Recent updates include central a/c, a newer furnace, hot water heater, washer, and dishwasher, ensuring comfort and peace of mind. This home offers single-family living at its best, with no monthly association fees or rules! Don’t miss the chance to settle into this adorable neighborhood just outside of downtown Portsmouth & enjoy the best of Seacoast living.
