Nearly 5,000 square feet | 5 Bedrooms | 5.5 Bathrooms | Finished Lower Level & Third Floor | Luxury New Construction in the Heart of Haddonfield. Welcome to 12 Mountwell Avenue, an exceptional new construction home offering nearly 5,000 square feet of thoughtfully designed living space in one of Haddonfield's most desirable neighborhoods. Blending timeless architecture with modern luxury, this custom-built residence was inspired by the town's historic Colonial and Victorian homes while delivering the craftsmanship, efficiency, and amenities today's buyers expect. The striking exterior showcases classic white James Hardie fiber cement siding, steep gabled rooflines, charming dormer windows, elegant architectural details, and a welcoming covered front porch that creates exceptional curb appeal. Inside, expansive windows fill the home with natural light, complementing an open-concept floor plan designed for both everyday living and effortless entertaining. The heart of the home is a stunning chef's kitchen featuring premium cabinetry, 10' center island, Taj Mahal quartzite countertops, a walk-in pantry, and a full suite of Monogram appliances. The adjoining family room, anchored by a gas fireplace, flows seamlessly to the rear deck and paver patio, creating the perfect indoor-outdoor living experience. Beautiful white oak flooring extends throughout the main living areas and second floor, while designer lighting, custom millwork, and carefully curated finishes elevate every space. With five spacious bedrooms, five full bathrooms, and a powder room, the home offers exceptional flexibility for families, guests, and work-from-home living. The finished lower level and finished third floor provide additional space for recreation, fitness, media, or private guest accommodations. Built with quality and efficiency in mind, the home features closed-cell spray foam insulation with additional sound insulation between floors, dual-zone HVAC, tankless dual water heaters, in-wall speaker system, and premium materials and upgrades throughout. Perfectly situated just moments from Haddonfield's award-winning schools, vibrant downtown shopping and dining, parks, and the PATCO Speedline, this home offers the rare opportunity to enjoy the benefits of luxury new construction while embracing the charm and character of one of South Jersey's most sought-after communities.
