Welcome to 3 Newcastle Place, an exceptional 4-bedroom, 4.5-bath Colonial offering over 4,700 square feet of beautifully finished living space in one of Unionville's most desirable neighborhoods. Impeccably maintained and thoughtfully enhanced, this home offers a level of quality, craftsmanship, and turnkey luxury increasingly difficult to find-even in new construction. Inside, 9-foot ceilings, hardwood floors, a natural gas fireplace, and an exceptional floor plan create a sense of sophistication and scale. The primary suite is a true retreat with a private en suite bath and impressive oversized walk-in closet. A second bedroom features its own en suite, while two additional bedrooms share a Jack-and-Jill bath. Bedroom-level laundry adds convenience, while the finished lower level, completed in 2023, provides additional versatile living space. Outside, enjoy a heated saltwater pool installed in 2024, beautiful landscaping, a new shed, and Green Giant arborvitae planted for enhanced privacy as they mature. A 3-car garage with electric heat, tankless hot water, 3-zone heating, and radon mitigation complete this truly move-in-ready home.
