Penthouse G at 280 Saint Marks Avenue offers a rare combination of scale, design, and private outdoor living within a full-service boutique condominium in the heart of Prospect Heights. This split layout two-bedroom, two-bath residence spans 1,321 square feet of interior space and nearly 1,000 square feet of private outdoor area across two levels, including a wraparound balcony and an upper rooftop terrace. The home also includes a deeded private parking space and two large deeded storage units-a truly uncommon combination, as penthouse-level two-bedrooms with expansive outdoor space and private parking are rarely available in today's market. Designed by DXA Studio, the interiors pair modern craftsmanship and understated elegance. The well-proportioned great room anchors the home-an expansive, light-filled space framed by eight-foot-tall sliding-glass walls facing southeast and southwest. From morning through late afternoon, natural light fills the space and extends onto the wraparound balcony, creating a seamless connection between indoor and outdoor living. Wide-plank oak floors, custom lighting, and clean architectural lines convey modern ease, while the open layout provides comfortable scale for both living and dining. The open chef's kitchen, subtly set off from the great room, features custom Italian cabinetry, Olympian Danby marble countertops, and a walnut-wrapped breakfast bar. Premium appliances include a Wolf range with externally vented hood, paneled Miele dishwasher, and Liebherr refrigerator, complemented by a Julien sink and Dornbracht fixtures. Pendant lamps by Brendan Ravenhill add refinement and warmth, while an owner-added sliding pantry cabinet offers both functionality and visual continuity. The primary bedroom is a private retreat-serene, king-sized, and beautifully proportioned. Southwest-facing windows bring in abundant light and open onto the balcony for a seamless indoor-outdoor connection. A walk-through dressing area custom-built by Henrybuilt in black walnut and aged brass provides exceptional storage and craftsmanship, leading directly to the en-suite bath. The primary bath is spa-like and finished in honed Sugar White marble, with radiant-heated floors, a soaking tub, glass-enclosed shower with Waterworks fixtures, and a custom double vanity with walnut millwork and backlit medicine cabinets. The second bedroom, equally bright and also generous in scale, benefits from the same southern exposure and balcony access. Finished with owner-added maple millwork and a large double closet by California Closets, it offers flexibility as a guest room, home office, or den. The adjacent secondary bath, located off the hallway, features textured limestone walls, Bianco Dolomiti marble floors, and Waterworks fixtures. A skylit interior stair leads to the private rooftop terrace-an extraordinary outdoor living and entertaining space of roughly 800 square feet. Panoramic south-facing views sweep across the Brooklyn skyline. The terrace easily accommodates distinct lounging and dining areas, with a piped-gas Weber grill, while the surrounding green roof planted with sedum provides year-round texture and color. Additional features include sustainably harvested seven-inch white-oak flooring by Brooklyn-based Madera Trade, a vented LG washer and dryer, and a multi-zoned Daikin HVAC system. Owner upgrades include Lutron electric shades, retractable VistaView screens, California Closets, a Lumenture custom lighting system, and fixtures by Brendan Ravenhill and Apparatus. 280 Saint Marks Avenue is a study in thoughtful, approachable luxury-a 31-residence, full-service condominium offering a full-time doorperson, double-height residents' lounge with fireplace and pantry kitchen, landscaped garden by horticulturist Patrick Cullina, roof terrace, fitness center, children's playroom, bike storage, and package room. The building also benefits from a 421-a tax abatement, enhancing its long-term value and appeal. Set along a tranquil, tree-lined block just moments from Prospect Park, the Brooklyn Museum, and the cafés and boutiques of Vanderbilt Avenue, and with effortless access to multiple nearby subway lines. This penthouse residence represents a rare opportunity for modern, design-driven living, complete with generous outdoor space and private parking in the heart of one of Brooklyn's most sought after neighborhoods.
