With ample storage, a flexible layout, and breathtaking views, 31K is a rare opportunity to create your dream home in the sky.

Plaza 400 is a self-managed, full-service cooperative located in the heart of Sutton Place.

Additional features include a fully equipped fitness center with yoga/stretching studio, professional-grade laundry facilities, bicycle storage, and concierge services. A 24-hour doorman, on-site security, and live-in superintendent ensure attentive service and peace of mind.

The building is pet-friendly and permits pieds- -terre, co-purchasing, guarantors, and parents purchasing for children. Monthly maintenance includes all utilities. There is a 2% flip tax, paid by the buyer.

Conveniently located near dining, shopping, parks, and multiple transportation options, Plaza 400 offers a refined and service-oriented lifestyle in one of Manhattan's most established neighborhoods.
