46 Washington Avenue Tucked along a quiet, coveted street in Hyannis Port, where ocean breezes drift through the trees and privacy comes naturally, this rare 1.01-acre coastal retreat captures the timeless charm of Cape Cod. Built in 1900 and known as ''The Laundry, '' this 5-bed, 4.5-bath home once served Hyannis Port's grand hotels--its legacy still reflected in exposed beams, historic finishes, and a striking Dutch split door with decorative ironwork. Sunlight pours through oversized windows, while two classic brick fireplaces create warm, inviting living spaces. The spacious kitchen features white cabinetry, stainless appliances, and a Viking range, ideal for gathering after long days by the sea. Outside, the beautiful flat backyard offers exceptional potential--perfect for an Olympic-size pool, family compound, barn, ADU, or expanded gardens. Dual driveway access from Longwood Ave and Washington Ave adds convenience. Limited water views today with potential for enhancement. Just a short stroll to Eugenia Fortes Beach, Hyannis Port Golf Club, and Hyannis Port Yacht Club, with Main Street, ferries, and Cape Cod Hospital minutes away. Passing Title V in hand.
