A Ritz-Carlton hotel reborn as a Madison Avenue co-op

The Carlton House took its name from the residential wing of the Ritz-Carlton hotel at Madison Avenue and 46th Street, which was torn down in 1950 and 1951. In January 1950 The New York Times reported that the Astor Estate would replace it with a fifteen-story and penthouse hotel-service apartment building on Madison Avenue between 61st and 62nd Streets, run by the Ritz-Carlton Hotel Company. When it opened in the spring of 1951, The New Yorker counted 165 apartments behind a red brick and limestone facade, with lobby fixtures salvaged from the old Ritz. Residents over the years included Carlotta O'Neill, widow of playwright Eugene O'Neill, and General Lucius D. Clay. Harry Helmsley and Lawrence Wien bought the building in 1964 and renamed it the Helmsley Carlton House, and from 1985 Pierre Cardin's Maxim's, a near replica of the Paris original, filled its lower floors.

The architect, Kenneth B. Norton, gave the building a neo-Georgian design: a three-story limestone base with fluted pilasters, urns, and wreaths, a brown brick tower above, and faceted corners wrapped in grouped casement windows so that nearly every suite had corner rooms. Some accounts say Norton drew the design in 1940 and the war delayed construction, though the Daytonian in Manhattan history notes that the Ritz-Carlton's demolition was still a decade away in 1940. The building sits in the Upper East Side Historic District, so every later change to its facade has needed Landmarks Preservation Commission approval.

In 2010 the Helmsley estate sold the building to Extell Development and Angelo, Gordon & Co. for about $170 million. The commission approved Beyer Blinder Belle's conversion plan in July 2011: a gut renovation, a restored facade, a two-story rooftop addition, and a new five-story limestone townhouse on 61st Street that holds the residential lobby. Gary Barnett told The New York Times the roughly $350 million conversion cost more than tearing the building down and starting over. Extell sold the block-long retail space to Thor Equities for $277 million in January 2013, and sales of the 68 co-op residences opened that April at $2.9 million to $65 million. The retail and residential portions sit on a ground lease that runs to 2169.

Josh's view of The Carlton House

What you won't find on a listing portal, in Josh's own words.

Who it suits

For buyers looking for one of the best locations in Manhattan, it's hard to beat this address. Just steps from Fifth Avenue and Central Park, you have some of New York City's finest shopping, restaurants, and cultural attractions right outside your door. Whether you plan to live here full-time or use it as a pied-a-terre, owning a home in this condop is a wonderful opportunity to enjoy everything that makes Manhattan so special.

Buying here

For a boutique building in Lenox Hill, this property offers tremendous value and an impressive collection of amenities. Residents enjoy a 65-foot heated indoor swimming pool, a state-of-the-art fitness center, game room, steam room, and much more. It's rare to find this level of amenities in a building of this size. Whether you're looking for a place to call home or an investment property, this building is worth serious consideration. The convenient location at the edge of Midtown is also a major advantage for investors, with strong appeal to renters who want easy access to everything Manhattan has to offer.

The best lines

The C and F lines are particularly impressive, offering beautiful layouts and wonderful natural light. That said, all of the apartments have something special to offer, with bright, inviting living spaces throughout. You really can't go wrong. It simply comes down to which layout and residence best fit your lifestyle.

Mistakes buyers make

This edge of Midtown can certainly be busy, but that's also part of what makes it such an exciting place to live. The neighborhood has fantastic restaurants, including Serafina right across Madison Avenue, along with great shopping and plenty of grocery stores nearby. With easy access to the subway and a convenient commute to work, just about everything you need is within reach. If you enjoy the energy of Manhattan and the convenience of having everything at your doorstep, this is a terrific location to call home.

What a listing won't tell you

The location is hard to beat. You can walk out of your building and be just a few blocks from the famous Plaza Hotel, with Central Park and Fifth Avenue right nearby. There's something really special about living in this part of Manhattan. It has a charm and elegance that never gets old, and it's the kind of location that will always be in demand.
