Set on two flat, beautifully landscaped acres along a low-traffic street in Brookville, yet just minutes from major highways and shopping, this classic Colonial built in 1964 offers thoughtfully updated living space throughout. An extensive renovation touched nearly every corner of the home, from all new Marvin windows and doors to central air, updated heating, and a full repaint inside and out. The kitchen underwent its own complete transformation, emerging with high end appliances, a center island, and gas cooking, ideal for anyone who loves to cook and entertain. Three fireplaces warm the home throughout, found in the den, the living room, and the sunroom, where a new gas fireplace adds year round comfort. Upstairs, five bedrooms include a primary suite with a walk-in closet and an en suite bath featuring a soaking tub, stall shower, and double vanity, while a sixth bedroom was converted into a convenient laundry room. Three full baths and two half baths serve the home's living spaces, and a full unfinished basement offers ample storage or future potential. The three car garage, expanded from its original two car footprint, sits above with a second story that shares a wall with the primary suite. Comfort continues with three zone heating and air conditioning, a 400 amp electrical service, an automatic propane generator, and a Control4 smart home system managing sound, lighting, and video throughout. Outside, mature landscaping surrounds a brand new in-ground pool, a pergola, and an outdoor kitchen with a gas BBQ, perfect for warm weather gatherings. A new thirty year asphalt roof, new driveway, and updated sprinkler system round out a home where every major system and finish has been thoughtfully addressed. Colonial in style and scaled for gracious living, 15 Dogwood Hill offers a rare combination of space, setting, and easy access to everything Long Island's North Shore has to offer.
