Introducing a Vanderploeg Team Exclusive at Douglas Elliman:  34 West 21st Street presents a rare opportunity to own a newly constructed 8,000 square foot turn-key 5 bedroom/5 bath one unit home, boutique office building or private members club in the heart of New York City. Designed by acclaimed architect Karl Fischer and interior designer Andres Escobar, this 7-story building represents a masterclass in modern architecture. Oversized windows, high-end finishes and soaring ceiling heights (including almost 16' on the parlor floor and 28' in the double height chef's kitchen) give the property a modern and open feel throughout. The private garage and commercial grade glass elevator provide easy access to and throughout the building. The large garden, roof terrace, and sauna provide a tranquil retreat in one of the liveliest neighborhoods in Manhattan. The C5-6 / R10A zoning is one of the most flexible in the city and permits nearly all commercial and residential uses. The Flatiron district offers the best of New York City including world class dining, art institutions and historic architecture. Notable venues just moments away include 11 Madison Park, Eataly, and Madison Square Park. Reach out to us via email or phone to schedule an appointment.
