Built in 2010 and tucked away on a quiet cul-de-sac in the sought-after Hailees Grove community, this modern colonial offers over 5,000 finished square feet, a flexible lower-level living suite, and nearly one-third of an acre designed for both everyday living and entertaining. Step inside through the dramatic two-story foyer featuring a statement staircase with convenient dual access from both the foyer and kitchen. The main level showcases hardwood floors, 9-foot ceilings, extensive trim and molding details, and a thoughtful floor plan with space for everyone. Work from home in the private office with French doors, host holidays in the formal living and dining rooms, or unwind in the inviting family room with a gas fireplace. A bright sunroom extends off the kitchen, creating the perfect spot for morning coffee overlooking the backyard. The gourmet kitchen features granite countertops, stainless steel appliances, 42” cabinetry, and a spacious center island with gas cooktop and additional seating, making it the heart of the home. Upstairs, the expansive primary suite feels like a true retreat, opening through a separate sitting room into a spacious bedroom with soaring cathedral ceilings. Thoughtful details include a walk-in closet, additional storage tucked beneath the dormers, and a large ensuite bathroom with dual vanities, soaking tub, separate shower, and private water closet. A dedicated laundry room with cabinetry is conveniently located just outside the primary suite. Three additional bedrooms complete the upper level. The second bedroom is adjacent to its own dedicated full bathroom accessible from the hallway, while bedrooms three and four share a Jack and Jill bathroom. Plush carpeting runs throughout the bedroom level. The finished lower level offers incredible flexibility with space ideal for guests, multi-generational living, an au pair suite, or extended stays. A large recreation room is prewired for surround sound and features a wet bar, French doors leading to the backyard, and an additional tucked-away bonus room. A full bathroom and oversized storage room add even more functionality. Outside, enjoy your own private retreat with a large two-level Trex deck, retractable awning, stone patio, and expansive flat backyard framed by hydrangeas and privacy trees. Additional features include dual-zone HVAC systems (2017), whole-home water filtration system, and lawn irrigation system.
