About this home
Welcome home to this beautifully renovated expanded Cape Cod, perfectly nestled in one of Watchung's most treasured settings directly across from the peaceful waters of Watchung Lake. Every morning feels a little more magical here, with picture-perfect views right from your living room windows, letting the light dance in and making the whole space feel calm, grounded, and connected to nature. Step inside and you'll find a custom eat-in kitchen designed for gathering, with quartz countertops, timeless finishes, and thoughtful details that make everyday meals feel special. The main level offers two spacious bedrooms with a warm, comfortable feel, while the second floor adds three more charming bedrooms and a beautifully updated full bath, giving everyone their own cozy corner of the home. Downstairs, a large open finished basement creates the perfect flex space movie nights, a playroom, a home gym, or all of the above. An attached garage adds convenience, and the generous lot opens to a lovely paver patio just off the kitchen ideal for morning coffee, weekend barbecues, or quiet evenings unwinding outdoors. What truly sets this home apart is its location. Near park, tennis courts, playground, and wide-open spaces, an extension of the lifestyle this home offers: peaceful, connected, and meant to be enjoyed. This is more than a house. It's a place to slow down, take in the lake views, and create a life that feels both inspiring and deeply comforting. Welcome to your Watchung retreat.
