353–355 4th Street is an architectural showpiece: a 37.5-foot-wide, modern two-family residence that stands out in the heart of Downtown Jersey City. The wood-and-stucco facade is framed by modern metal and glass, and the home offers one of the area’s rarest amenities, an attached garage plus a private, walled backyard. Behind the burnt-orange doors, the entry level provides direct access from the garage into a mudroom with a sink and ample storage, opening to the backyard. As a legal two-family, the property also includes a separate one-bedroom, one-bath apartment on this level with its own private entrance, ideal for guests, extended family, or extra income. A dramatic glass staircase topped by a skylight leads to the second-floor main level: a full-floor open concept living, dining, family, and kitchen space anchored by custom built-ins and glass-paneled interior partitions. Light maple floors and rich walnut millwork create a warm, tranquil backdrop, while floor-to-ceiling rear windows frame the private, walled garden and keep the outdoors in view. The kitchen offers sleek white cabinetry and refined quartz countertops wrapped by warm walnut and a top-of-the-line appliance suite, including a Wolf dual-fuel 6-burner range, Viking French-door refrigerator, Bosch dishwasher, and a wine cooler. A substantial walnut island adds seating at the center of the room. From the kitchen, a metal staircase leads directly down to the backyard for easy grilling and outdoor dining; in cooler months, gatherings shift to the living area centered around a gas fireplace. A built-in Sonos sound system is integrated throughout the home, including the main level, bedrooms, and baths, and custom walnut cabinetry in the family and dining areas adds both function and warmth. On the third floor, four comfortable bedrooms and two full baths are arranged off the central staircase, which is illuminated from above. The primary suite includes a massive, fully outfitted walk-in closet, and the conveniently located laundry on this level simplifies daily life. The primary en-suite features teak wood floors along with a floating vanity and contemporary tilework, while the additional bath continues the clean, modern aesthetic. With its rare width, thoughtful layout, attached garage, and beautifully detailed interiors, 353–355 4th Street is a distinctive Downtown Jersey City home where design, comfort, and everyday practicality come together.
