The Best Pre-War Co-ops on the Upper East Side: 17 Buildings

The short answer: the best pre-war co-ops on the Upper East Side are the ones buyers keep paying the most for, and by that measure the list is short. We started with buildings on Fifth and Park Avenue that have either one recorded sale above $30 million or several above $20 million, checked against public record. Fifteen qualify: ten on Fifth Avenue and five on Park. We added two more Park Avenue buildings, 730 Park and 770 Park, on the strength of the buildings themselves. Most were designed by a small group of architects, led by Rosario Candela and J.E.R. Carpenter, and they offer what new construction rarely repeats: a real dining room, a gallery entry, and walls that hold sound. Here is each building, what it offers, what it has sold for, and how to approach the board.

What a classic six is, and what it is not

A classic six has six main rooms: a living room, a formal dining room, a kitchen, two full bedrooms, and a smaller room originally built for live-in staff. That last room is usually near the kitchen, and today it works as a study, a guest room, or a third bedroom.

The count is strict. Bathrooms, entrance galleries, and hallways do not count toward the six, whatever a listing says. Ask for the floor plan before you ask about the price.

• Separate rooms for entertaining and for private use, rather than one open plan

• Entry gallery that organizes the apartment and keeps the living room off the front door

• Original details in intact apartments: moldings, hardwood floors, and often a wood-burning fireplace

Why downtown buyers look uptown

Downtown apartments are built around volume and light: tall ceilings, big windows, open plans. Uptown pre-war apartments are built around plan. Rooms have doors, service space is separated from living space, and the layout does the work that furniture does downtown.

The trade is the board. Every building on this list is a co-op, which means an application, a financial review, and an interview. Prices for co-op space have often sat below comparable new condominiums, and the difference is the price of that process. Know it going in.

Who designed them

Rosario Candela is the architect most associated with luxury apartment buildings on Fifth and Park Avenue before World War II. His plans are known for proportion and for generous square footage inside limestone exteriors.

J.E.R. Carpenter was an earlier and equally influential name, the leading designer of luxury residential high-rises in the early 1900s. His buildings tend to be conservative on the outside and generous on the inside. When you see either name on a building, expect a plan that was thought through.

The 17 buildings at a glance

Two patterns stand out. The largest sales cluster on Fifth Avenue, where park-facing full floors set the market, and seven of the ten Fifth Avenue buildings have recorded a sale above $30 million since 2014. On Park Avenue, 740 Park is in a category of its own, while the highest sales at 720, 778, and 640 Park all date from 2008 and 2009. Every figure in this guide is a recorded sale, and any specific apartment should be judged on its own floor, exposure, and condition.

Park Avenue: seven pre-war co-ops

740 Park Avenue. Designed by Candela with Arthur Loomis Harmon and completed in 1930, it has 19 stories and about 31 residences, mostly duplexes and triplexes. This is not a classic six building; it is a different product at a different scale, and it has the deepest sales record on Park. A six-bedroom duplex recorded at $71.3 million in August 2014, the building's highest sale, and two combined duplexes sold for $52.5 million in 2012. More recently, a five-bedroom duplex sold for $45 million in February 2025, another five-bedroom duplex sold for $38 million in April 2026, and a duplex penthouse sold for $28 million in December 2023.

720 Park Avenue. Candela designed it with Cross & Cross, and it was completed in 1928. The building has its own squash court, and its original terraced duplex, with a 40-foot entrance gallery, was later divided in two. A seventh-floor apartment recorded at $36.6 million in December 2008. The building has several more sales above $20 million, including $24 million and $23 million in 2013 and $20.05 million for a six-bedroom apartment in 2017.

778 Park Avenue. Candela designed it, and it was completed in 1931 with 18 floors over a four-story limestone base and 18 apartments, many of them full floors. The ground-floor maisonette has its own address on East 73rd Street. A six-bedroom apartment on the third floor sold for $33.6 million in January 2008, a four-bedroom sold for $28.5 million in 2015, and a six-bedroom sold for $27 million in 2019. The five-bedroom 12th floor sold for $24.95 million in May 2023 and again for $21.25 million in May 2026.

640 Park Avenue. J.E.R. Carpenter designed it, and it has 13 stories with one apartment per floor, some with as many as 18 rooms. It has been a co-op since 1946. Few buildings on Park have as consistent a record at this level: the 11th floor sold for $25.87 million in 2009, the eighth floor for $23 million in 2013, and the third floor for $20.5 million in 2011, with further full-floor sales at $20 million in 2012 and 2018.

895 Park Avenue. Sloan & Robertson designed it, and it was completed in 1930 with 19 stories and 36 apartments. The building went into foreclosure in 1931, early in the Depression, and residents bought it as a co-op in 1952. It has its own squash court. The six-bedroom penthouse that was once Leonard Bernstein's home sold for $24 million in October 2021 and was recorded again at $22.79 million in September 2026, and a five-bedroom triplex with terraces sold for $19.99 million in February 2026.

730 Park Avenue. Lafayette A. Goldstone and F. Burrall Hoffman Jr. designed it, and it was completed in 1929 at the northwest corner of Park and East 71st Street, inside the Upper East Side Historic District. It has 38 residences. Its highest recorded sale is the four-bedroom duplex penthouse with a wraparound terrace, which sold for $28.5 million in March 2025, and a five-bedroom apartment sold for $16.5 million the following month. It is here for the quality of the building and its apartments more than for its sales record.

770 Park Avenue. Candela designed it, and it was completed in 1930 at the southwest corner of East 73rd Street, with 19 stories and about 40 apartments. Its H-shaped plan brings light and air to every apartment, and the mix of duplexes and simplexes gives every unit a street orientation. Dorothy Draper decorated the lobby and hallways. Its highest recorded sale is $20 million in 2007, and a six-bedroom duplex sold for $17.75 million in 2013, which makes it one of the more accessible ways into a Candela building on Park.

Fifth Avenue: ten pre-war co-ops

4 East 66th Street (845 Fifth Avenue). J.E.R. Carpenter designed it with Cross & Cross, and it was completed in 1920, with one 18-room apartment per floor as originally built. Apartments have 11- to 13-foot ceilings, several wood-burning fireplaces, and entrance galleries of about 37 feet. It holds the record for a New York co-op: $101 million, recorded in June 2022. A fifth-floor apartment sold for $52 million in 2016, the eighth floor for $43 million in 2020, and a five-bedroom apartment for $37 million in March 2025.

834 Fifth Avenue. Candela designed it, and it was completed in 1931 at East 64th Street facing Central Park, with 16 stories and 24 residences. Apartments run from roughly 3,500 to 10,000 square feet, with setback terraces on the upper floors and three street-level maisonettes. A five-bedroom duplex recorded at $77.5 million in March 2015, a co-op record at the time. A ten-bedroom duplex sold for $53 million in 2019, and the triplex penthouse sold for $44 million in 2005.

960 Fifth Avenue. Warren & Wetmore designed it, with Candela as supervising architect, and it was completed in 1928 on the site of the old Clark mansion. It is known for very large apartments with generous service quarters, and it has an in-house restaurant, the Georgian Suite, with its own entrance on East 77th Street. A penthouse sold for $70 million in 2014, a five-bedroom apartment for $55 million in 2017, and the full eight-bedroom 12th floor for $53.5 million in January 2025.

2 East 67th Street. Candela designed it, and it was completed in 1928, with 13 stories, 14 apartments, and 11-foot ceilings. The 11th floor sold for $48 million in 2008, then the most ever paid for a New York co-op. The market here has stayed strong: the ninth floor sold for $36 million in June 2024, after selling for $26 million in 2007, and the third floor sold for $30 million in 2017.

820 Fifth Avenue. Starrett & van Vleck designed it, and it was completed in 1916, with 12 stories of full-floor apartments of about 6,500 square feet and two lower duplex maisonettes.

The seventh floor sold for $45 million in July 2026, the 12th floor for $40 million and the six-bedroom fourth floor for $33 million in 2009, and the six-bedroom third floor for $27.5 million in January 2025.

998 Fifth Avenue. McKim, Mead & White designed it, and it was completed in 1912 as an all-limestone Italian Renaissance palazzo facing the Metropolitan Museum. It has 12 floors and 17 apartments, and no penthouses. A five-bedroom apartment overlooking the park and the museum sold for $37.5 million in September 2025, after last selling for $23.5 million in 2017. The building has a long record above $20 million, including $27.5 million in 2007, $27.2 million in 2012, and $22 million in 2021.

907 Fifth Avenue. J.E.R. Carpenter designed it, and it was completed in 1916 as the first apartment building to replace a private mansion on Fifth Avenue above 59th Street. A four-bedroom apartment on the 12th floor sold for $37.5 million in January 2025, and a three-bedroom on the eighth floor sold for $26.72 million in 2016.

927 Fifth Avenue. Warren & Wetmore designed it, and it was completed in 1917 with 12 floors and one apartment per floor. Its cornice is also known as the home of Pale Male, the red-tailed hawk that nested there for decades. The four-bedroom 11th floor sold for $29.1 million in 2010 and again for $34.6 million in 2011. The fifth floor sold for $26 million in 2012, and the six-bedroom ninth floor sold for $24.5 million in December 2024.

1040 Fifth Avenue. Candela designed it, and it was completed in 1930 with 27 apartments. Jacqueline Kennedy Onassis lived in its top-floor penthouse from 1964 until 1994. A five-bedroom apartment sold for $32 million in 2016, and three more apartments have sold for $30 million each, in 2006, 2011, and 2015. A four-bedroom duplex with a 30-foot living room sold for $25 million in May 2023.

Also worth considering

These buildings each have strong sales but fall just outside the list above: 1020 Fifth Avenue, across from the Metropolitan Museum, where the top floor sold for $26.75 million in 2011 and a full floor with 20-foot ceilings sold for $21 million in 2018; 820 Park Avenue, where a combined duplex sold for $22 million in 2014; and 625 Park Avenue, where a combined duplex sold for $21.5 million in 2014.

If you want the look without a board

737 Park Avenue is a pre-war Art Deco tower, designed by Sylvan Bien and completed in 1940, that was converted to a condominium in 2014. It has 60 residences across 20 stories, many with the proportions and light of classic Park Avenue layouts. Because it is a condominium, it allows pied-à-terre, non-resident, and entity purchases that most co-ops restrict. For some buyers, that flexibility outweighs everything else on this list.

Which boards are realistic to get through

Board rules are not published, and they change with the board. Anyone who gives you a fixed list of requirements for a specific building is guessing. What holds across the top Park and Fifth Avenue buildings is the shape of the process: a complete financial package, verified liquidity, references, and an interview.

The buildings on this list are not equally hard. Smaller buildings and buildings with large apartments tend to look closely at the whole household balance sheet, not just income. Do the work before you fall in love with an apartment, not after.

• Confirm the building's financing rules and any minimum liquidity before you tour seriously

• Have your financial package assembled before you make an offer, not after

• Read the offering documents for the flip tax, the underlying mortgage, and recent assessments

• Ask your agent what recent approvals looked like in that building, and how long the process took

• Ask whether an apartment is an intact classic six or a combination of units, since the alteration history affects both layout and board comfort

What to check when you tour

Pre-war apartments vary more than new construction does. Two apartments in the same building can feel like different products. Use the tour to answer specific questions.

• Exposure and floor: which direction the main rooms face and what they look onto

• Whether the dining room and gallery are original or have been opened up

• The condition of the kitchen and bathrooms, and what the alteration agreement would require to change them

• Whether the staff room has been kept, converted, or absorbed into another room

• How much of the original detail survives: moldings, floors, and fireplaces
