The MetLife Building (also 200 Park Avenue and formerly the Pan Am Building) is a skyscraper at Park Avenue and 45th Street, north of Grand Central Terminal, in the Midtown Manhattan neighborhood of New York City. Designed in the International style by Richard Roth, Walter Gropius, and Pietro Belluschi, the MetLife Building is 808 feet (246 m) tall with 59 stories. It was advertised as the world's largest commercial office space by square footage at its opening, with 2.4 million square feet (220,000 m2) of usable office space. As of 2021[update] the MetLife Building remains one of the 100 tallest buildings in the United States.
The MetLife Building contains an elongated octagonal massing with the longer axis perpendicular to Park Avenue. The building sits atop two levels of railroad tracks leading into Grand Central Terminal. The facade is one of the first precast concrete exterior walls in a building in New York City. In the lobby is a pedestrian passage to Grand Central's Main Concourse, a lobby with artwork, and a parking garage at the building's base. The roof also contained a heliport that briefly operated during the 1960s and 1970s. The MetLife Building's design has been widely criticized since it was proposed, largely due to its location next to Grand Central Terminal.
Proposals for a skyscraper to replace Grand Central Terminal were announced in 1954 to raise money for the New York Central Railroad and New York, New Haven and Hartford Railroad, the financially struggling railroads that operated the terminal. Subsequently, plans were announced for what later became the MetLife Building, to be built behind the terminal rather than in place of it. Work on the project, initially known as Grand Central City, started in 1959 and the building was formally opened on March 7, 1963. At its opening, the building was named for Pan American World Airways, for which it served as headquarters. The Metropolitan Life Insurance Company (MetLife) bought the Pan Am Building in 1981 and subsequently used it as their headquarters before selling the building in 2005. The MetLife Building has been renovated several times in its history, including in the mid-1980s, early 2000s, and late 2010s.
The MetLife Building is at 200 Park Avenue, between the two roadways of the Park Avenue Viaduct to the west and east, in the Midtown Manhattan neighborhood of New York City. The building faces the Helmsley Building across 45th Street to the north and Grand Central Terminal to the south. Other nearby buildings include the Yale Club of New York City clubhouse to the west, across Vanderbilt Avenue; The Roosevelt Hotel to the northwest, across Vanderbilt Avenue and 45th Street; 450 Lexington Avenue to the east; and the Graybar Building to the southwest.
In 1871, the New York Central Railroad built the Grand Central Depot, a ground-level depot at the intersection of Park Avenue and 42nd Street; it was succeeded in 1900 by Grand Central Station, also at ground level. The completion of Grand Central Terminal in 1913 resulted in the rapid development of the areas around Grand Central, which became known as Terminal City. The Grand Central Terminal complex included a six-story building for baggage handling just north of the main station building, on what is now the site of the MetLife Building. The baggage handling building was converted to an office building late in its history. The surrounding stretch of Park Avenue was developed with International Style skyscrapers during the 1950s and 1960s.
Designed in the International style by Richard Roth, Walter Gropius and Pietro Belluschi, the MetLife Building was completed in 1963. It is 808 feet (246 m) tall with 59 stories, containing both commercial and office space. As of March 2021[update], the MetLife Building is the 31st-tallest building in New York City and 74th-tallest in the United States.
The Diesel Construction Company was the general contractor for the building's construction. Numerous other engineers and contractors were involved in the building's construction, including Hideo Sasaki as site planning consultant and landscape architect; Jaros, Baum & Bolles as consulting engineers; and James Ruderman as structural engineer. From the beginning, the building was intended for large firms, with 2.4 million square feet (220,000 m2) in office floor area. In total, it has 2,841,511 square feet (263,985.0 m2) of gross floor area, according to The Skyscraper Center.
As designed, the MetLife Building's massing contains a base of nine stories, atop which is an octagonal section of fifty stories. Outside the building, both on the sidewalks and above the roof of the base, were planted areas.
The tower stories' floor plates are designed in an elongated octagonal lozenge, with the longer axis running parallel to 45th Street. The north and south facades are divided into three broad segments, while the west and east facades are one segment each. The building's form may have been influenced by the 1961 Zoning Resolution, a major change to New York City zoning code that was proposed just before construction started. The massing is similar to Le Corbusier's unbuilt tower in Algiers, proposed between 1938 and 1942, as well as the nearly contemporary Pirelli Tower in Milan. The octagonal shape and exterior curtain wall were intended by the architects to reduce the building's perceived sense of scale.
The facade of the first two stories and mezzanines is clad with granite, aluminum, marble, and stainless steel with glass windows. On Depew Place, an alley running below the eastern leg of the Park Avenue Viaduct, fifteen loading docks were constructed for trucks to conduct deliveries and loading. The third through seventh stories are exclusively sheathed in granite, with window inserts. The eighth and ninth floors, which are slightly set back, are clad in aluminum.
The 10th through 59th stories of the MetLife Building contain one of the first precast concrete exterior walls in a building in New York City. About nine thousand light-tan precast concrete Mo-Sai panels were installed, each measuring 6 feet (1.8 m) wide by 13.67 feet (4 m) high. The panels each contain one window measuring 4 feet (1.2 m) wide by 8 feet (2.4 m) high. Each panel, weighing 3,500 pounds (1,600 kg), is coated with a quartz aggregate to give texture to the facade. Vertical concrete mullions project from the facade, separating the panels on every story. Flat concrete spandrels separate the windows between stories. The curtain wall is positioned slightly behind the columns on the 21st and 46th stories, where there is mechanical space.
The Pan Am Building originally bore 15-foot-tall (4.6 m) "Pan Am" displays on its north and south facades and 25-foot-tall (7.6 m) globe logos on the east and west facades. This was swapped with neon "MetLife" displays to the north and south in 1992. These displays were changed again in 2017, being replaced with LED letters to conserve energy. The MetLife Building was the last tall tower erected in New York City before laws were enacted preventing corporate logos and names on the tops of buildings. Modern New York City building code prohibits logos from being more than 25 feet (7.6 m) above the curb or occupying over 200 square feet (19 m2) on a blockfront. The sign replacements had been permitted because the city government considered the new signs to be an "uninterrupted continuation of a use" that was allowed before the zoning laws were changed.
The MetLife Building was built atop two levels of railroad tracks underground, which feed directly into Grand Central Terminal. The substructure of the building uses foundational columns that extend into the track levels, descending some 55 feet (17 m) below street level into the underlying bedrock. The substructure includes more than 300 columns, each 18.5 inches (470 mm) across and clad with 2 inches (51 mm) of concrete. Ninety-nine columns were built specifically for the MetLife Building; these columns were installed within several inches of existing steel members such as third rails, but had to be isolated from the other steel. The new columns weighed between 22 and 44 short tons (20 and 39 long tons; 20 and 40 t). Approximately two hundred existing columns, which supported the former baggage building on the site, were reinforced. The work involved abridging the tops of many existing columns and installing horizontal beams weighing up to 36 short tons (32 long tons; 33 t). A "triple decker sandwich" made of lead, asbestos, and sheet steel was installed under each level of tracks to provide insulation.
The superstructure was constructed similarly to bridge spans. To fabricate the floor slabs, builders used a process called composite action, in which concrete was bonded with structural steel panels to create a stronger structure. Steel panels were fabricated, rather than concrete floors, because steel panels were lighter and could be constructed regardless of unfavorable weather. Over 56 acres (230,000 m2) of steel panels are used in the floor plates, each of which contains wire and cable ducts. A standard floor slab could handle loads of 50 pounds per square foot (240 kg/m2). The building's steel frame weighs over 45,000 short tons (40,000 long tons; 41,000 t) in total. The roof of the building contains NOAA Weather Radio Station KWO35, a National Weather Service radio station.
The initial plans for the MetLife Building were altered in March 1961 to provide for a helipad on the east side of the roof. The heliport required approval from the Federal Aviation Administration (FAA), the city government, and the Port Authority of New York and New Jersey. After a contentious approval process, helicopter service started on December 22, 1965. The service was operated by New York Airways, which flew Vertol 107 helicopters from the rooftop helipad to Pan Am's terminal at John F. Kennedy International Airport (JFK). For a short period starting in March 1967, the company also offered service to Teterboro Airport. All helicopter service stopped on February 18, 1968, because of insufficient ridership, as well as disagreements over the helicopter contract.
Though discussions to restart helicopter service were held in 1969, approval was not given until early 1977. Service to JFK resumed that February using Sikorsky S-61s. On May 16, 1977, about one minute after an S-61L landed and its 20 passengers disembarked, the right front landing gear collapsed, causing the aircraft to topple onto its side with the rotors still turning. One of the five 20-foot (6.1 m) blades detached, killing four men who were waiting to board, then fell to the ground, where it killed a woman on the corner of Madison Avenue and 43rd Street. Two other people were seriously injured. Helicopter service was suspended that day and never resumed. During its short periods of operation, the heliport was largely perceived as a nuisance and danger, but its presence was also seen as satisfying what David W. Dunlap described as "the consummate technological fantasy of airborne travel through skyscraping pinnacles".
A central telephone office was installed on two of the upper floors, serving 30,000 telephones within the offices of tenants. The central office, operated by New York Telephone, eliminated the need for tenants to have individual telephone offices and equipment rooms. To avoid interfering with the subterranean railroad tracks, the telephone conduits were routed through the roof of the railroad tunnel. On the two floors where the telephone office was installed, the floor slabs could handle loads of 150 to 300 pounds per square foot (730 to 1,460 kg/m2), and floor heights were increased to provide clearance of at least 13.5 feet (4.1 m).
A refrigeration plant, described at the time of construction as the world's largest such plant, was installed on the roof with three steam-powered units each weighing 3,333 short tons (2,976 long tons; 3,024 t). The plant was placed on the roof because the building has no usable basement, as all the subterranean space is part of Grand Central Terminal. The plant could melt up to 20 million pounds (9.1 kt) of ice each day and could use 200,000 pounds of steam every hour. Large fan rooms were placed on the mechanical stories at the 21st and 46th floors, dispersing air to the other floors, and two individual air supply systems were placed on each story. The ventilation systems could deliver 5,000,000 cubic feet (140,000 m3) every minute. The pipes and ducts had to serve all the building's floors, with an electrical system and water pressure system capable of serving all the building's stories. At ground level was a room where wastepaper could be "baled" on-site to make easier to dispose of paper.
Westinghouse Electric Corporation also manufactured 65 elevators and 21 escalators for the MetLife Building, which at the time of construction was the largest-ever order for elevators. One bank of six elevators was able to travel 1,600 feet per minute (490 m/min), the fastest elevators in the world at the time of their installation. Five elevators were reserved for freight. The elevators rise from the second-story lobby because the elevator pits could not descend below the first story due to the presence of the tracks. According to the Skyscraper Center, as of 2021[update] the building has 85 elevators.
The MetLife Building's base contains a lobby across its lowest two stories. At ground level is 76-foot-wide (23 m) pedestrian passageway, enabling pedestrian traffic flow between the Helmsley Building's pedestrian arcades and Grand Central Terminal. The 45th Street entrance to the passageway is set back 65 feet (20 m) from the sidewalk. A 103-foot-wide (31 m) entrance arcade is placed on Vanderbilt Avenue, with the doorways set about 81 feet (25 m) back from the sidewalk there. The building's main office lobby is placed at the second story, at the level of the viaduct. The lobby was also designed with plantings and a 40-foot-high (12 m) enclosed plaza. Four escalators lead to the Main Concourse at the southern end of the passageway, while fourteen more lead from the passageway to the office lobby. Staircases between the first and second floors, and some 15,000 square feet (1,400 m2) of retail space, were constructed in the lobby during a 1980s renovation. The storefronts were removed in the late 2010s and the lobby was reclad in light colored travertine.
The lobby was planned with several works of art. One such artwork is Flight, a triple-story wire sculpture by Richard Lippold. The sculpture contains a sphere, representing the earth; a seven-pointed star, representing the seven continents and seas; and gold wires representing aircraft flight patterns. The composer John Cage, a friend of Lippold's, had initially proposed a musical program to complement Flight, but Lippold canceled the idea and management instead agreed to play classical music in the lobby. At the Pan Am Building's opening, the entrance from the Main Concourse was topped by Manhattan, a 28-by-55-foot (8.5 by 16.8 m) mosaic mural of red, white, and black panels by Josef Albers. That work was removed in a 2001 renovation, though a replica was installed in 2019. Suspended over the 45th Street entrance was an architectural mural by György Kepes, consisting of a set of aluminum screens with concentric squares, which was also removed in the 21st century. At Vanderbilt Avenue, Robert Berks sculpted a bronze bust depicting Erwin S. Wolfson, who had developed the Pan Am Building.
The MetLife Building was designed with a six-level parking garage with room for 400 cars. The garage contains entrances and exits from both roadways of the Park Avenue Viaduct. According to owner Tishman Speyer, as of 2021[update], the building's garage contains 248 spots across four levels.[a]
A variety of commercial and office spaces were included in the Pan Am Building when it opened. Pan Am, the airline for which the building was originally named, contained a ticketing offices at 45th Street and Vanderbilt Avenue, similar in design to Eero Saarinen's TWA Flight Center at JFK Airport. Office stories in the octagonal slab typically have between 32,000 to 36,000 square feet (3,000 to 3,300 m2) of usable space, with elevators and stairs at the center, as well as uneven column spacing. This arrangement allows a large amount of window-office space for tenants, as each story contains 780 feet (240 m) of outer perimeter walls. Different companies with full-floor leases designed their spaces in various manners. Some tenants placed private offices along the perimeter, with important executive offices at the far corners of the story. Other tenants placed open spaces at the west and east ends of the floor or in the center.
The Sky Club, a private luncheon club, had been on the 56th floor of the Pan Am Building. For several years the Sky Club had contained a private restaurant. Aircraft pioneer Juan Trippe, founder of Pan Am, was a member of this club. Trippe had commissioned a mural of clipper ships for the walls of the Sky Club; it was sent to Tucker's Point resort in Bermuda after the club shuttered. On the 57th and 58th stories was the Copter Club, which was used by passengers of the short-lived helicopter service.
By the 1950s, passenger volumes at Grand Central Terminal had declined dramatically from the early 20th century, and there were proposals to demolish and replace the station. The New York Central Railroad was losing money, partially on paying taxes on the building's air rights. New York Central wanted to sell the property or its air rights to allow the construction of a skyscraper above or on the terminal's site. At the same time, the New York, New Haven and Hartford Railroad retained a partial interest in the terminal's operation.
Initially, New York Central's chairman Robert R. Young had been negotiating with developer Erwin S. Wolfson and their mutual friends Herbert and Stuart Scheftel to determine how the Grand Central site could be redeveloped. After these discussions broke down, two competing plans for the replacement of Grand Central Terminal were proposed in 1954. One design, by I. M. Pei, was suggested by Young along with developer William Zeckendorf. The proposal called for an 80-story, 5-million-square-foot (460,000 m2) tower that would have succeeded the Empire State Building as the world's tallest building. The other, by Fellheimer & Wagner, was put forth by New Haven's chairman Patrick B. McGinnis along with Wolfson. The plan envisioned a 55-story building, the largest office building in the world with 4 to 6 million square feet (370,000 to 560,000 m2). Both proposals were poorly received, with 235 architects cosigning a letter imploring Young and McGinnis to reject the plans. Neither plan was ultimately ever carried out.
Though the New Haven and New York Central continued to struggle financially, both railroads agreed to work with Wolfson, the New Haven's developer. In February 1955, Wolfson, the Scheftels, and Alfred G. Burger proposed a 65-story tower called Grand Central City, which would replace a six-story baggage structure north of the terminal. The design was created by Richard Roth of Emery Roth and Sons, who agreed to participate only if the office building would not result in the passenger concourse's demolition. Roth and Wolfson's plan was effectively forgotten one month later when Zeckendorf was named the partner for any new development in the vicinity of Grand Central.
Roth's plan was resurrected in May 1958, with some revisions. The plan called for a 50-story aluminum and glass tower parallel to Park Avenue, with 3 million square feet (280,000 m2) of floor area; three theaters with a total capacity of 5,000; an open-air restaurant on the seventh floor; and a 2,000-spot parking garage. The New York Central and New Haven railroads were guaranteed at least $1 million a year from the agreement. Despite the presence of tracks under the building site, Wolfson said a survey of the site had "no insurmountable problems". Wolfson, however, found Roth's revised plan to be unsatisfactorily modest for such a prominent site. He said in the New York Herald Tribune that he wanted to "avoid adding just another massive shape to an already developed midtown business community".
In July 1958, architects Walter Gropius and Pietro Belluschi were announced as co-designers for Grand Central City. Wolfson expressed his hope that Gropius and Belluschi, both prominent architects in the Modern style, would be able to help devise an "esthetic and functional design". That October, Wolfson traveled to Europe to study buildings and obtain inspiration for how Grand Central City could be redesigned. The revised final plans were announced in February 1959. While Wolfson had promised a "modest" redesign, the new plans were a radical change from Roth's 1958 plan, calling for a 55-story octagonal tower parallel to 45th Street, with 2.4 million square feet (220,000 m2) of space. Roth said the octagonal massing could absorb "different planes of light as on a diamond", while Gropius said the new alignment was easier for air conditioning. A model of the redesigned tower was exhibited publicly in November 1959.
Five leases for a collective 600,000 square feet (56,000 m2) in Grand Central City were announced immediately after the final design was announced in February 1959. A contract for 40,000 short tons (36,000 long tons; 36,000 t) of structural steel was awarded to U.S. Steel's American Bridge division that May; at the time, the contract was reportedly the most expensive ever awarded for an office building. The projected $100 million cost of the building was difficult for Wolfson's concern to cover, but British firm City Centre Properties invested $25 million in the project in October 1959, taking a half interest in Grand Central City's development. The New York Central Railroad granted an 80-year lease for the air rights above the building, in exchange for a portion of the building's gross revenue.[b] This agreement added about $6 million to the construction cost. Final plans were filed with the New York City Department of Buildings on November 24, 1959. Construction on the structure officially started two days afterward. Cushman & Wakefield were named as leasing agents for Grand Central City the following month.
James Ruderman, the building's structural engineer, had devised engineering plans for five other structures above the Park Avenue railroad tracks. As the Grand Central City site was impossible to excavate, the substructure had to be erected while the baggage building served as a staging area. Furthermore, as some materials would have to be delivered by railroad, material deliveries would be coordinated closely to avoid delays on the commuter rail lines entering Grand Central. Work on the tower itself was held up by a steel strike that lasted through much of 1960; the baggage handling building was ultimately demolished starting that June. Foundations for the building were sunk in August 1960. The next month, Pan Am founder Juan Trippe signed a 25-year, $115.5 million lease in September 1960, allowing the airline to occupy 613,000 square feet (56,900 m2) across 15 floors, plus a new main ticket office at 45th Street and Vanderbilt Avenue. Grand Central City officially became known as the Pan Am Building in December 1960, after its major lessee. Signs bearing the company's name or logo were placed atop all four major facades.
The Pan Am Building's developers secured a $70 million mortgage loan and a $65 million construction loan during January 1961. At the time, the building was more than half rented. Three derricks were installed to erect the steel for the tower, while four derricks were used for the base. Five to seven steel columns were installed every day during two shifts, with materials deliveries taking place mostly at night. The Pan Am Building's structural steel topped out during May 1962. The facade cladding was installed in two ways. The facade of the base was bolted into place, down to the individual spandrels and mullions. The Mo-Sai panels for the tower were installed via an interior hoist. Wolfson, though recovering from surgery during mid-1962, continued to observe the building's progress using a helicopter. When Wolfson died that June, James D. Landauer was selected to oversee the building's completion. The lobby, the last part of the Pan Am Building to be completed, was built with cheap materials such as restroom tiles because the builders had run out of money toward the project's completion.
The Pan Am Building was formally opened on March 7, 1963, despite not being completed, and tenants started moving into the structure the following month. Initially, the airline only had a 10 percent ownership stake in its namesake building. Besides Pan Am, other early tenants included the Westinghouse Electric Corporation, Alcoa, the Hammermill Paper Company, National Steel Corporation, Kodak, Reader's Digest magazine, Mitsui, Chrysler, and British Iron & Steel Corporation. The shops at the Pan Am Building's base were opened in August 1963. The tenant selection process was rigorous, as Cushman and Wakefield examining the services and goods sold by potential tenants: for example, the firm's vice president got haircuts from each of the six applicants for the lobby barbershop. Furthermore, average rents in the Pan Am Building were about $6.75 per square foot ($72.7/m2), slightly higher than the average of $5.25 to $6 per square foot ($56.5 to $64.6/m2) in other Midtown Manhattan buildings. Nevertheless, by the first anniversary of its opening, the Pan Am Building was 97 percent leased, with 241 tenants.
At the time of its completion, the Pan Am Building was the largest commercial office space in the world by square footage. The building was surpassed in size by the World Trade Center in 1970 as well as 55 Water Street in 1972. Although the Pan Am Building's completion averted the terminal's imminent destruction, New York Central had experienced further decline, merging with the Pennsylvania Railroad in 1968 to form the Penn Central Railroad. That year, Pan Am bought a 45 percent stake in the building from Jack Cotton's estate. After Penn Central went bankrupt in 1970, it sought to sell its properties, including the land below the Pan Am Building. Among the building's tenants during this time was the United Brands Company (now Chiquita Brands International), whose CEO, Eli M. Black, jumped from the 44th story to his death on February 3, 1975.
Pan Am was considering moving its headquarters from the building by 1978. That year, the company bought the remaining 45 percent stake in the building from Wolfson, obtaining full ownership of the property. A Pan Am subsidiary, Grand Central Building Inc., acquired the underlying land for about $25 million the following year as part of a legal settlement with Penn Central. The airline subsequently sustained large financial losses during the early 1980s recession and placed the building for sale in February 1980. About half the leases were scheduled to expire in three or four years, and many lessees were exempt from paying the building's operating costs, which made the Pan Am Building only marginally profitable for the airline. Nine bidders submitted offers, five of which were selected for further consideration: the Metropolitan Life Insurance Company (MetLife), the Equitable Life Assurance Society; Donald Trump; Paul Milstein; and Olympia and York.[c]
In July 1980, Pan Am sold the building to MetLife for $400 million. MetLife did not plan to move any offices to the building, and Pan Am planned to retain its headquarters there. The sale was finalized in 1981 when Pan Am transferred stock in the building to MetLife, a move that let the airline avoid paying an estate transfer tax. Cross & Brown assumed the responsibility of leasing the building's space. Starting in 1984, MetLife renovated about half of the space as the original tenants' leases expanded. The deteriorating lobby, used by 100,000 pedestrians a day, was extensively reconfigured. In addition, some mechanical systems were upgraded to comply with building codes, and retail spaces were added. Asbestos fireproofing on the office stories was removed in advance of an anti-asbestos regulation passed by the city government in 1985. The lobby renovation had been completed by 1987.
By 1991, Pan Am's presence had dwindled to four floors, and MetLife preferred to refer to the building as 200 Park Avenue, its address. At the time, the Pan Am Building was 95 percent occupied, and the public variously referred to the building by the names of its large tenants, such as Mitsui, Dreyfus, and Rogers & Wells. Pan Am moved its headquarters to Miami that year and closed down shortly afterward. In September 1992, MetLife announced that it would remove Pan Am signage from 200 Park Avenue and add letters bearing its own name. According to a MetLife spokesperson, the sign change was occurring because the airline had become defunct. The signs were changed in January 1993. Though 200 Park Avenue subsequently became known as the MetLife Building, its namesake was then headquartered in the Metropolitan Life Insurance Company Tower.
Further renovations to the MetLife Building's exterior and lobby were undertaken during 2001 and 2002. Subsequently, in 2005, MetLife moved its board room from the Metropolitan Life Tower to 200 Park Avenue. The same year, the company considered selling 200 Park Avenue to pay for its acquisition of Travelers Life & Annuity. Ultimately, MetLife sold the building that April for $1.72 billion, to a joint venture of Tishman Speyer Properties, the New York City Employees' Retirement System, and the New York City Teachers' Retirement System. At the time, the sale was the largest ever transaction involving an office building. The company still retained a boardroom and corporate suite at 200 Park Avenue.
MetLife announced in 2015 that it was consolidating its operations at 200 Park Avenue, with 500,000 square feet (46,000 m2) of space in the building. At the time, the media reported that Donald Bren, the billionaire owner of the real estate firm Irvine Company, held a 97.3 percent ownership stake in the building. While Tishman Speyer remained the managing partner of the property, the company's stake in the MetLife Building had been reduced to less than 3 percent. Plans to renovate the lobby were devised in 2016. The next year, the neon light sources for the signs atop the building were swapped with LED light sources to conserve energy. A renovation of 200 Park Avenue's lobby was commenced the following year. The work was meant to simplify the lobby's layout by removing storefronts and restoring direct connections to some of Grand Central's platforms.
When the octagonal design for 200 Park Avenue was first announced in 1959, it was controversial. Architectural historian Sibyl Moholy-Nagy wrote in Progressive Architecture magazine that the original tower plans "provided human scale and architectural personality", which were "lost" in the revision. Walter McQuade, writing for The Nation, found even the drawings for the building to be dissatisfying. Grand Central City was lambasted internationally by Italian critic Gillo Dorfles and Romanian architect Martin Pinchis. Architect Victor Gruen questioned the parking garage's necessity given the site's proximity to a major railroad terminal, while Progressive Architecture editor Thomas H. Creighton suggested the space would be better left as an open plaza. Critics also expressed concerns that the building would burden existing transit infrastructure. The plan also had its defenders, such as Natalie Parry, who wrote in rebuttal to Moholy-Nagy that the plans preserved Grand Central's "star-studded" Main Concourse, "together with the precious air space above it". Historian Paul Zucker defended the building's urbanism, and urban planner Charles Abrams and Architectural Record editor Emerson Goble also defended the plan as an addition to the cityscape.
Upon its completion, the Pan Am Building received largely negative feedback from critics. James T. Burns Jr. wrote in Progressive Architecture that the placement of the base, tower, parking garage, and Grand Central Terminal were "occasionally inexcusably jarring" and considered the lobby to be a continuation of the exterior's "monolithism". Ada Louise Huxtable called the building "a colossal collection of minimums", with the lobby artwork being a "face-saving gimmick". Many observers viewed the monolithic design as obstructing vistas down Park Avenue. Art historian Vincent Scully, speaking in 1961, expressed his belief that the Pan Am Building was a "fatal blow" to Park Avenue's continuity, while Claes Oldenburg mocked the building's positioning on Park Avenue with his 1965 artwork Proposed Colossal Monument for Park Avenue, NYC: Good Humor Bar. A 1987 poll conducted by the lifestyle periodical New York indicated the MetLife Building was the building that New Yorkers would most like to see demolished. Architect Robert A. M. Stern said in 1988 that the building, a "wrong-headed dream badly realized", warranted preservation from the New York City Landmarks Preservation Commission, although he rhetorically suggested tearing down the building when the Pan Am sign was replaced several years later.
By the beginning of the 21st century, some onetime critics expressed ambivalence toward the building's presence, while preservationists advocated to preserve mid-20th century buildings such as the MetLife Building. ArchDaily magazine described it in 2016 as "commendable for its robust form and excellent public spaces, as well as its excellent integration into the elevated arterial roads around it". Furthermore, the building's reputation and presence made it the setting of several films or TV shows during its history.
