400 E 56TH Street Unit MEDICAL, New York, NY 10022

$1,695,000

Unlock unparalleled flexibility in the heart of Sutton Place with this expansive 3,257-square-foot unit. Situated on the ground floor of the prestigious Plaza 400, this property is a rare unicorn in the Manhattan market: a legally zoned live/work co-op. Whether you are a medical professional seeking a flagship practice, an… Read More entrepreneur looking to eliminate a commute, or a savvy investor, this property offers a footprint and utility that are nearly impossible to find in the current inventory. The space is defined by its versatility and scale, featuring two distinct entrances to maintain a professional boundary. Clients and patients can utilize the private street-level entrance, while the residential side is accessed through the building's elegant, white-glove lobby. Currently configured as a high-capacity medical suite, the layout is optimized for efficiency with multiple exam rooms, a dedicated reception area, and administrative zones. For those seeking a premier residential footprint, we have developed a proposed floor plan demonstrating how a portion of the space can be seamlessly reimagined into a sprawling 3-bedroom, 3-bathroom luxury residence while still maintaining a fully functional professional wing. This property represents a powerful financial strategy, priced significantly below the average Midtown Manhattan price per square foot. By consolidating a luxury residence and a professional office into a single mortgage, owners can eliminate separate commercial rent, capitalize on significant tax advantages, and build long-term equity in a high-value asset. Triple exposures to the south, east, and west ensure the expansive interior remains bright and inviting throughout the day. Plaza 400 is a world-class, self-managed co-op offering a lifestyle of convenience and prestige. Residents enjoy access to the Skytop Club, featuring a seasonal rooftop pool and lounge with 360-degree views of the skyline and East River. The building provides comprehensive service with a 24-hour doorman, concierge, and on-site management. Additional amenities include a state-of-the-art fitness center, children's playroom, on-premises valet garage, and bike storage. Notably, the monthly maintenance is all-inclusive, covering central air, heat, and electricity. Located in the quiet, tree-lined enclave of Sutton Place, the building is minutes from the city's leading hospitals, corporate headquarters, and premier dining, providing a peaceful escape without sacrificing Midtown access. The co-op permits pied-à-terre use and guarantors. All floor plans, dimensions, and conversion configurations are approximate estimates only and should be independently verified by the buyer and their architect or professional consultant. Read Less
