Property Description

Every inch of this extraordinary 6-bedroom, 3-bath Colonial tells the story of an architect's vision brought to life — because it was. Thoughtfully designed and built by the sellers themselves, 2185 Sycamore Avenue is a one-of-a-kind residence where craftsmanship and character are woven into every detail. From the soaring cathedral and tray ceilings to the rich natural woodwork, and built-in features, the quality here simply cannot be replicated. Spanning 3,612 sq ft on nearly half an acre, the home offers 13 rooms including a formal dining room, eat-in kitchen with breakfast room, a first-floor bedroom and full bath, a great room with wood-burning stove, second floor laundry room and a stunning primary suite with sitting room, walk-in closet and 4 piece en-suite bathroom. This home offers plenty of space with an open floor plan and a layout also conducive to multigenerational living. The oversized detached 4-car garage with its own 100-amp panel is a car enthusiast's dream, while the 9' + basement ceilings open endless possibilities — think golf simulator, home gym, or studio. Outside, a serene backyard waterfall and semi-inground fiberglass pool create a true private retreat, complete with multiple fruiting trees including a peach tree, cherry tree, cherry plum tree, and blueberry bush! Major systems updated in 2006 including the boiler and roof when the extension was done. Just minutes from the newly revitalized Ronkonkoma LIRR hub with trendy dining, shopping, and express access to Manhattan and the LIE — this is Long Island living at its finest.
