54 St. Marks Place is a stunning, gut renovated and thoughtfully expanded townhouse. Spanning over 20 feet in width, with approximately 5,000 square feet of interior space and 1,700 square feet of exterior, the home offers a seamless blend of modern infrastructure and custom design across multiple levels. With the addition of a newly constructed penthouse floor and effortless indoor-outdoor living throughout, this triple mint residence delivers both scale and flexibility. The parlor floor is the true centerpiece of the home, anchored by a striking custom European kitchen where slabs of Viola natural stone take center stage, wrapping the countertops and waterfall island with dramatic veining and depth. The island serves as both a visual focal point and functional gathering space, complemented by integrated Bosch appliances and clean, modern cabinetry. At the rear, a dramatic 22-foot double-height ceiling with expansive glass creates an incredible sense of volume and light, overlooking the garden and bringing the outdoors directly into the living space. The living room flows seamlessly to a private balcony, while a defined dining area completes the level with ease and elegance. The garden level offers a large recreation space with direct access to the landscaped garden, creating a natural extension of the home suited for entertaining, lounging, or play. A powder room and additional flexible space complete the level. The primary suite occupies its own floor and is designed as a true retreat, offering exceptional scale, two walk-in closets, a separate office, and an ultra-luxurious bath finished with Viola stone and a freestanding soaking tub. The proportions are generous and serene, creating a private and comfortable escape within the home. Three additional bedrooms are thoughtfully arranged across the upper levels, each well-proportioned with excellent light and storage, along with two bathrooms finished with detailed tile work and natural stone. The newly added penthouse level functions as a flexible living space, complete with a wet bar and wine fridge, and opens to expansive terraces with open exposures. Whether used as a lounge, media room, or additional entertaining area, it adds a highly functional and versatile dimension to the home. Throughout, finishes have been selected with a focus on quality and longevity, including herringbone white oak flooring, custom millwork, and carefully curated stone. The infrastructure has been fully upgraded with new Pella windows, a new roof, heavy-gauge cold steel framing with Big Apple joists, a high-efficiency hot water system, gas furnace heating, and three-zone central air conditioning. Additional features include a multi-zone Juke audio system, alarm system, and laundry on both the third floor and lower level. With a custom landscaped garden, multiple outdoor spaces including a balcony and rooftop terraces, and a triple mint renovation throughout, this townhouse offers exceptional scale, seamless indoor-outdoor living, and a level of finish that feels both elevated and effortless.
