Welcome to 144 Dawn Drive in Shirley, a beautifully maintained home combining generous living space, a flexible layout, and everyday convenience in a location that keeps you close to everything you need. Built in 2010 by the current owner's family, this home has had just one owner and has been carefully maintained from the beginning. The first floor features a bright, open layout connecting the living room, dining area, and kitchen, creating a comfortable flow that works equally well for everyday living and entertaining. Sliding doors from the kitchen lead directly to the backyard and a recently installed large patio, making it easy to enjoy indoor-outdoor living throughout the warmer months. Whether you're hosting a gathering, enjoying dinner outside, or simply relaxing at home, the backyard gives you plenty of room to make the space your own. The first floor also includes an additional living area that adds valuable flexibility. With proper permits and approvals, this space may have the potential to be converted into a first-floor bedroom. Nearby, the half bathroom sits beside an oversized pantry, and buyers who may not need the extra pantry space could explore the possibility of expanding the half bath into a full bathroom, also subject to proper permits and approvals. Upstairs, you'll find three bedrooms and two full bathrooms, including a spacious primary suite with its own private full bathroom and an oversized closet. The home continues to provide even more space downstairs with a large basement featuring high ceilings and a separate outside entrance. It's a great area for recreation, storage, a home office, hobbies, or other permitted uses. Set on a generously sized property along a quiet street, there is plenty of outdoor space for relaxing, entertaining, gardening, and enjoying time at home. The location is another major highlight. Beaches, parks, schools, shopping, medical facilities, places of worship, and major roadways are all just minutes away. The Mastic-Shirley LIRR station is also nearby, making travel toward New York City more convenient. Major banks, retailers, coffee shops, restaurants, and everyday necessities are all close at hand, including Home Depot, Starbucks, Dunkin', McDonald's, Applebee's, Chipotle's, Wendy's, Taco Bell, Sonic, Dollar Tree, The UPS Store, CVS, Marshall's, Stop&Shop, and so much more, there's too many to list. With its spacious layout, flexible living areas, large property, convenient location, and the opportunity to become only its second owner, 144 Dawn Drive is ready for its next chapter.
