About This Home

21 Hillside Avenue

Overlooking the shimmering waters of the Long Island Sound, this exquisite four-bedroom, three-bath Colonial is a masterclass in coastal elegance and timeless design. Gracefully elevated and thoughtfully renovated, it offers a front-row seat to Long Island’s most breathtaking sunsets and a lifestyle steeped in tranquility. Behind its classic facade lies a luminous interior, fully reimagined in 2018 to blend sophisticated charm with luxurious modern comforts. The heart of the home is a sun-kissed kitchen adorned with gleaming quartz countertops, rich custom cabinetry, and an effortless flow into the open-concept living and dining areas — all perfectly positioned to showcase breathtaking uninterrupted views. Multiple decks invite you to float above the scenery, savoring morning coffee, hosting twilight cocktails, or simply basking in the ever-changing coastal light. Enjoy one-of-a-kind sunrises from the balcony and sunsets from the private beach. The serene primary suite is a private sanctuary, where panoramic water views and a spa-like en-suite bath evoke a perpetual vacation. Three additional bedrooms offer versatile space for family or guests. A charming detached one-car garage complements the home’s coastal aesthetic, while every detail — from flooring to fixtures — speaks to quality, care, and enduring style. Nestled in a coveted waterfront enclave with deeded beach rights and just minutes from the vibrant shops, dining, and theater of Northport Village, as well as Del Vino Vineyard, this rare gem offers more than a home — it offers a lifestyle. Fall in love with coastal living where charm, comfort, and beauty meet.
