1646 Carlton Street is a masterclass in contemporary architecture and modern luxury. Set within the gated NOVO community in Logan Square—just steps from the city’s most celebrated museums—this 28-foot-wide, 4-bedroom, 6-bath residence blends dramatic design with impeccable craftsmanship. The exterior makes an unforgettable first impression with intricate modern brickwork, custom metal cladding, striking window compositions, and a floating stone terrace. A custom solid walnut pivoting door leads into a gracious foyer, where a first-floor office or guest suite faces the street, complete with custom built-ins and a corner window. Direct interior access to the three-car garage adds ease and convenience. Throughout the home, radiant heated floors provide unparalleled comfort and refinement—visible evidence of the home’s elevated standard of construction. Ascending to the main living level, you pass a sculptural powder room defined by its dramatic stone backsplash. The primary living floor unfolds into a breathtaking open space—minimalist yet warm—anchored by a European chef’s kitchen with a massive Super White quartzite island and matching full-height backsplash. Appliances are all top-tier, including a Thermador built-in coffee maker, double wall ovens, integrated knob cooktop, drawer microwave, Sub-Zero refrigerator, and pot filler. Custom lighting adds a gallery-like ambiance. Adjacent to the kitchen, the living room is nothing short of extraordinary, offering a double-height volume, cove lighting, and a sleek gas fireplace wrapped in porcelain. Floor-to-ceiling glass opens to a private balcony with pedestal pavers, creating effortless indoor/outdoor connectivity. A dining area with a fully outfitted butler’s pantry completes this level, supported by thoughtful details such as linear slot diffusers and large-format floor tiles. Take the floating staircase—or elevator—to the mezzanine level, which overlooks the living room below. This floor includes a lounge or family room and two well-proportioned bedrooms, each with en-suite baths. The primary suite occupies an entire level and functions as a private retreat in the sky. A full wet bar with stone counters and beverage refrigeration anchors the landing, and a concealed door reveals the laundry room. The bedroom features soaring ceilings and a dramatic 10-foot Pella sliding glass wall opening to a private balcony. The walk-in closet resembles a boutique dressing room, complete with center island and custom organizers. Pocket doors lead to the spa-inspired bath, featuring a Porcelanosa soaking tub, expansive glass shower, and a floating double vanity with wall-integrated Brizo faucets. At the top of the floating staircase, an additional half bath precedes the rooftop terrace—over 800 square feet of private outdoor living. This extraordinary space includes a louvered pergola, an outdoor kitchen with a stainless grill, and a luxurious Bullfrog Stil7 tub. Panoramic skyline views make this rooftop one of the most impressive private outdoor spaces in the city. The lower level echoes the feel of a boutique hotel lounge, featuring a custom bar, integrated sound system, and a separate fitness room (4th bedroom) and a full bath. The home’s smart-tech infrastructure is extensive, including Lutron Lighting System, automated shades by Allure, multiple HVAC zones, whole-home audio, and more. 1646 Carlton Street is not just a residence—it is a work of modern art, offering sophisticated architecture, exceptional craftsmanship, and a lifestyle unmatched in the heart of Philadelphia.
