Description

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 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.
