About This Home

421 E Cottage Ave

Thoughtfully designed from top to bottom, this exceptional custom residence pairs refined architectural detail with true resort-level amenities—an offering rarely found in Haddonfield. Privately positioned at the end of a cul-de-sac and bordered by wooded open space, the home delivers modern luxury, craftsmanship, and privacy without compromise. Wide-plank wood flooring flows throughout the home, complemented by custom millwork, decorative wall detailing, and carefully curated lighting. The open-concept kitchen and family room serve as the heart of the home, featuring dual oversized islands, granite countertops, a walk-in pantry with custom shelving, and a premium appliance suite including Sub-Zero refrigeration and a Wolf range and oven. A custom commercial-style hood, wet bar with beverage refrigerator, and gas fireplace complete this inviting yet sophisticated space—ideal for everyday living and entertaining alike. The primary suite is a true retreat, highlighted by custom decorative ceiling beams, motorized Hunter Douglas window shades, and a Lutron lighting system. The spa-inspired bathroom offers heated floors, a soaking tub, dual vanities, a private water closet, and an expansive walk-in shower with dual stations and overhead rainfall shower. An oversized walk-in closet with custom built-ins and a cabinet island completes the suite. The four other generously sized bedrooms provide flexible living, including en-suite and Jack-and-Jill bathroom arrangements, all finished with custom closet shelving and abundant natural light. A finished, fully conditioned attic bonus room adds valuable additional living space, while a second-floor lounge overlooks the dramatic two-story foyer below. Designed for both productivity and relaxation, the home features a private office with a striking iron-and-glass entry door, custom wood detailing, built-in bar, motorized shades, and access to a side porch. The lower level is an entertainer’s dream, offering a custom theater room with granite viewing counter, game and lounge spaces, a sound-insulated home gym, and a dedicated spa and wellness area complete with a large built in sauna, RENU therapy cold plunge, seating lounge, and full bathroom. The luxury resort feel continues outside. Enjoy the pool and hot tub with a mechanical cover, raised covered patio, custom masonry pool deck, expansive lawns, and a fully fenced yard lined with Green Giant arborvitae for privacy. An oversized two-car garage, generous laundry room with extensive cabinetry, integrated security system, and multiple sump pumps complete this thoughtfully executed home. A rare opportunity to own a meticulously crafted residence where luxury, privacy, and lifestyle converge—this is Haddonfield living at its finest.
