Philip Birnbaum (1907-1996) was a Columbia-trained New York architect credited with roughly 300 buildings, most of them apartment houses built for the city's largest postwar and 1980s developers. His reputation rested on plan efficiency rather than on design, and his obituary noted that his buildings had virtually no wasted floor space. Costas Kondylis worked in the office from 1979 to 1989. Eight buildings in our catalog carry the credit, including One Lincoln Plaza, 30 Lincoln Plaza, Bristol Plaza, Evans Tower, The Promenade, and The Strand. The name carries no premium; it signals decade, scale, and developer economics.
Who he was
Philip Birnbaum was born in Manhattan in 1907, grew up in Washington Heights, went to Stuyvesant High School, and took his architecture degree at Columbia. He had been accepted at Princeton, which then discouraged him from enrolling on the grounds that he might not fit the environment — he was Jewish. He opened his own practice and worked until near the end of his life. He died in Manhattan on November 27, 1996, at 89.
Counts of his output vary. Most published accounts put it at roughly 300 buildings, mainly in Manhattan and Queens; some sources say well over 300. His clients were the large postwar and 1980s developers — the Milsteins, Peter Kalikow, the Glick organization, Alfred Kaskel, Donald Trump. His obituary in the Times noted that his buildings had virtually no wasted floor space, which is the shortest accurate description of what he sold.
Costas Kondylis worked in the office from 1979 to 1989 before opening his own firm. Two buildings in our catalog carry the credit in the form our records inherited it — "Costas Kondylis of Philip Birnbaum & Associates" — and that is how they were published at the time.
The work
Eight buildings in our catalog carry the Birnbaum name. They divide by neighborhood and by decade.
The Lincoln Square pair are the largest. One Lincoln Plaza (20 West 64th Street) is 43 residential floors over an eight-story commercial base, roughly 660 apartments depending on how combinations and the commercial and garage components are counted. Its trapezoidal footprint comes from a holdout owner on West 63rd Street whose five-story building the tower was designed around. Dates differ across sources: our building records give construction from 1971 and occupancy in 1974, and published architectural listings variously say 1970, 1972, and 1974. 30 Lincoln Plaza (30 West 63rd Street) followed in 1979–80, 33 stories and about 578 apartments, converted to condominium in 2009 with a large sponsor-retained block still rented.
The East Side group is mostly 1987. Evans Tower (171 East 84th Street) is 36 stories and 217 condominiums, set behind a privately owned public plaza, built by Legent Realty. Bristol Plaza (200 East 65th Street) is 50 stories and 308 units, credited to Ulrich Franzen & Associates with Philip Birnbaum & Associates, developed by Milstein Properties with Robert Olnick. The Promenade (535 East 75th Street / 530 East 76th Street) is about 38 to 39 stories and 209 units for the Glick organization, carrying the Kondylis credit.
On the West Side, 500 West 43rd Street (The Strand) is 42 stories and roughly 311 residences, also under the Kondylis credit; sources put its completion anywhere from 1987 to 1989. In Midtown East, 846 Second Avenue, known as the Delegate, is a 21-story masonry tower from 1979, built as a rental and converted to condominium in 1985.
278 Park Avenue South (Gramercy Place) is the outlier. The base is the 1894 New York Bank for Savings by C.L.W. Eidlitz, restored by Beyer Blinder Belle; the residential tower above it is Birnbaum's, added in the 1980s conversion. The building runs 26 floors and roughly 258 to 261 apartments, a range that public records do not resolve.
Outside our catalog the same office produced Trump Plaza on Third Avenue, the Hotel Parker Meridien, the interior of the Galleria, and a large body of Queens work — the Kennedy House in Forest Hills, 34 stories and the borough's tallest at completion in 1966, and Dara Gardens in Kew Gardens Hills, named for his daughter, the video artist Dara Birnbaum. One account credits his 1954 Roosevelt Terrace in Jackson Heights as the first building in the country to put terraces on both facades of every apartment.
How the work is regarded
There is very little published criticism of Birnbaum as a designer, and the architectural histories of the period mostly pass over him. One survey of postwar Queens architecture describes him as prolific and largely forgotten. He worked for developers on developer economics and was measured on rentable efficiency, and that is the standard the buildings were designed to meet.
The wider criticism of the postwar apartment house lands on his cohort. The white glazed brick tower — roughly 140 of them went up in New York between the 1950s and the 1970s — was treated by critics as cheap, repetitive, and indifferent to the street. The practical complaint arrived later: white brick stains, spalls, and needs more facade maintenance than the alternatives, which is what New York magazine documented in 2011 under the headline "Covered in White Brick, and Showing Their Age." Some reappraisal has followed. The 2008 restoration of 900 Fifth Avenue was the first landmark-quality restoration of a white brick building.
Two qualifications matter for our catalog. First, most of the Birnbaum buildings here are 1979 through 1989 work in beige and brown masonry and glass, one decade past the white brick era. Second, the criticism that does apply to them is urbanistic. These are plaza-and-tower buildings designed under the 1961 zoning resolution, and the plaza bonus that made them taller also pulled several of them back off the street line. Evans Tower sits behind exactly such a plaza. Whether that trade reads as generous or as a hole in the block is a judgment you can make standing on the sidewalk.
We have found no Birnbaum building with individual landmark designation. His 424 West End Avenue falls within the Riverside–West End Historic District Extension I.
What the credit means for value
The name carries no premium. It tells you the decade, the developer economics, and the plan discipline. Price the apartment, the line, and the building's financials.
These are big buildings, and that cuts both ways. From 209 to roughly 660 apartments, the fixed cost of staff and amenities spreads across a wide base, which holds common charges down. The same scale means many comparable units, so a resale is priced against a visible internal market and rarely gets the benefit of scarcity.
Terraces and setbacks are the strongest part of the product. Birnbaum used terraces early and often. Where a line has private outdoor space at these price points, that is usually where the value sits.
The buildings are now in the expensive part of the capital cycle. A 1979 to 1989 tower is 35 to 45 years old, with facade, window, elevator, and mechanical work either done or pending. Confirm the reserve balance, the most recent Local Law 11 filing, and assessment history. Buildings above 25,000 square feet — all of these — also sit inside Local Law 97's compliance window, and our Local Law tools will show a specific building's exposure.
Read the conversion history before the architecture. 846 Second Avenue converted in 1985; 30 Lincoln Plaza converted in 2009 and still carries a substantial sponsor-held rental block. Sponsor concentration affects board control, financing, and how a lender views the building.
Confirm the attribution. Bristol Plaza is a shared credit with Ulrich Franzen & Associates. The Strand and The Promenade are published as Kondylis work done inside the Birnbaum office. Where our building page states the source of a credit, use that rather than the shorthand.
Buying one today
Price against the block and the line. The comparable set is the neighboring 1980s condominium stock, adjusted for floor, exposure, and outdoor space. In towers of this size, the line matters more than the address.
Get the unsold-unit position in writing. This is the first question at 30 Lincoln Plaza and worth asking everywhere in the group.
Ask for the facade and window history. Masonry and window assemblies of this vintage are the largest single variable in what you will pay to own the apartment over ten years.
Test light and exposure on the actual floor. Efficient plans mean less circulation and more room area, and these towers were built close to each other. What the floor plan promises and what the window delivers are two different facts.
Working with The Roebling Team
Large 1980s condominiums reward building-level diligence more than architectural interest. The spread between two lines in the same tower, or between two towers on the same avenue, is usually a matter of reserves, sponsor position, and facade history. If you are buying or selling in one of them, start with a thirty-minute consultation.
