With 4,050 finished square feet, this spacious home offers generously proportioned living areas, abundant natural light, recessed lighting, and a traditional yet functional floor plan.

A whole-home generator was added in 2017, providing added convenience and peace of mind. // Hardwood flooring extends throughout the main level, beginning in the welcoming foyer and continuing to the left into the formal living room and to the right into the elegant formal dining room, enhanced by detailed lower wainscoting. Beyond, hardwood floors continue into the inviting open-concept great room, which seamlessly brings together the kitchen, family room, and breakfast room. // The beautifully renovated gourmet eat-in kitchen features a spacious island with breakfast bar seating, upgraded quartz countertops, stainless steel appliances, a classic white subway tile backsplash, and a second breakfast bar that opens to the cozy breakfast room. The breakfast room offers a higher vaulted ceiling and direct access to the deck, creating a bright space for casual dining and entertaining. The spacious family room features a gas fireplace and provides a warm gathering space for everyday living. Completing the main level are a convenient powder room and a versatile bonus room that is ideal for a home office or main-level guest room well suited for multigenerational living. // The upper level features four generously sized carpeted bedrooms, two full bathrooms, and a well-appointed laundry room with a washer and dryer replaced in 2025. The spacious owner's suite offers a tray ceiling, walk-in closet, and private en-suite bathroom with dual sinks, a soaking tub, and a separate walk-in shower. An additional highlight of the upper level is the louvered arch window, added in 2022, which brings distinctive architectural character to the space. // The fully finished, walk-out lower level expands the home's living and entertaining possibilities. Plush carpeting extends throughout the spacious recreation room, which features a granite wet bar, a dedicated media center and lounging area, and ample space for a game or dining table. A versatile bonus room offers endless possibilities for a guest room, home gym, playroom, or hobby space. A full bathroom and utility room complete the lower level. // Outdoor living is a true highlight, with a spacious deck and lower-level patio offering inviting areas for outdoor dining, entertaining, and relaxing.
