This beautifully updated and thoughtfully expanded Cape Cod offers a rare large main-level primary suite and the versatility to easily convert into a four-bedroom home. Perfectly situated on a quiet street in sought-after Seminary Valley, the home combines timeless charm with modern comfort and stunning gardens for relaxing outdoor living. A welcoming portico opens to a gracious foyer, where rich hardwood floors flow throughout the main level. The formal living room, anchored by a wood-burning fireplace framed with custom built-ins, is filled with natural light from a boxed bay window dressed in plantation shutters. The adjoining dining room showcases elegant crown molding, a built-in buffet with glass-paneled cabinetry, and a striking hexagon-tile backsplash. The remodeled kitchen is a chef's delight, featuring white shaker cabinetry with pull-out drawers and under-cabinet lighting that highlights Silestone countertops and a fresh new backsplash. Stainless steel appliances, breakfast bar seating, and classic hardware complete the space. The adjoining family room offers cathedral ceilings, newer windows, and a glass-paneled door that opens to the screened-in porch, perfect for relaxed gatherings. The main-level primary suite is an inviting retreat, offering a spacious sitting area, three custom closets, built-in dresser, and crown molding. This flexible space can easily be reconfigured to create a fourth bedroom if desired. The primary bath features a walk-in shower with dual showerheads, pedestal sink, and built-in cabinetry. Upstairs, two charming bedrooms with custom closet organizers (one with a walk-in) share a well-appointed hall bath. Additional storage is available in bedrooms' attic eaves. The lower level provides a bright recreation and game area with replaced windows, a craft or hobby room with built-ins, an updated laundry room with newer washer and dryer, and generous storage throughout. Step outside to your private backyard oasis. The screened-in porch with Trex-style flooring, vaulted beadboard ceiling, and a new ceiling fan overlooks lush, professionally landscaped gardens. A serene fountain anchors the circular paver patio, surrounded by graceful hardscaping and newly fenced yard with stepping stones that invite you to linger outdoors.
