Welcome to 633 Jersey Avenue, a breathtaking 1885 brownstone nestled in the heart of Downtown Jersey City’s coveted Hamilton Park neighborhood. Meticulously reimagined by Rose + Co Interiors, this two-family residence is a masterclass in "preservation-first" design. This rare offering features a palatial 4-bedroom, 3.5-bathroom owners’ triplex over a high-end 1-bedroom garden rental, blending soulful Victorian history with a complete 2021 infrastructure overhaul that ensures the home functions with the ease of new construction. The owners’ triplex is a curated sanctuary that honors its 19th-century roots while embracing a high-end, modern aesthetic. The parlor floor is anchored by original 1885 wide-plank pine floors—carefully bleached and whitewashed—and framed by meticulously restored plasterwork and crown moldings. The impecabbly designed living room provides a serene escape with soundproof Marvin windows and an original marble fireplace upgraded with a gas line. Nearby, the inviting library serves as a sophisticated focal point, featuring an antique fireplace mantle salvaged from the legendary Plaza Hotel in New York City and a "secret" rollout bookshelf that cleverly conceals the home’s mechanical room. The culinary heart of the home is a chef’s dream, featuring bespoke cabinetry dressed in European hardware, striking Arabescato Marble bacsplash, countertops and island. High-end matte black GE Café appliances and 6 burner range with a commercial-grade white hood ventented outdoors. This charming home features custom closets, built-ins and lighting fixtures throughout. This attention to detail extends to the private quarters, specifically the primary suite, which offers a spa-like retreat with honed marble tile, an oversized double vanity, and premium Waterworks fittings. Even the utility spaces are elevated, from the laundry room’s handmade Moroccan tile and Electrolux washer/dryer suite to the kids' bath with its original clawfoot tub and vintage Italian Stilnovo sconces. Beyond the visible beauty lies a total 2021 mechanical restoration. The home features all-new plumbing, electrical, and a new sewer line, alongside a 3-zone high-velocity HVAC system for precision climate control. Modern essentials like a whole-house water filtration system and a Navien tankless water heater provide peace of mind, while the exterior has been fully repointed with restored ironwork and a reconstructed brownstone stoop. The commercial-grade PVC membrane roof, installed in 2018, ensures long-term durability. Outdoor living is equally impressive, featuring a solid Trex back deck with an integrated drainage system. Unique to the area, the backyard offers a remarkably private view with no facing buildings or windows, creating a secluded urban oasis. Located just moments from the PATH train and the vibrant culture of Hamilton Park, 633 Jersey Avenue is a rare opportunity to own a designer-restored trophy property featured in Design NJ, perfectly balancing the charm of the past with the luxury of the present.
