After World War II, development of theaters around Times Square stalled, and the area began to evolve into a business district. The first proposal to convert the Astor Hotel site to offices had been put forth in 1947, when
Metro-Goldwyn-Mayer had unsuccessfully proposed leasing the entire hotel for its own offices. When real estate developers
Webb and Knapp leased the hotel in 1954, they pledged to keep the hotel operating. Astor Associates bought the hotel in 1958 and took over operation after Webb and Knapp went bankrupt in 1965. Webb and Knapp's former president
William Zeckendorf formed Place de L'Etoile Inc. in December 1965, seeking to buy the Astor Hotel, but this was unsuccessful.
Planning Initial plans In January 1966,
Sam Minskoff and Sons paid $10.5 million for the Hotel Astor and the eastern section of Shubert Alley, with plans to erect a 40-story office building on the site. At the time, a
tax assessment valued the land at $8.4 million. The Minskoffs hired Kahn and Jacobs as the architects in May 1966, and the hotel was closed on June 30, 1966, the day before Minskoff & Sons took
title to the site. The old hotel's furnishings were sold off in October 1966. The Minskoffs demolished the rear of the hotel first because there was a restaurant at the front of the hotel, whose lease did not expire until 1967. The Hercules Wrecking Corporation began demolishing the hotel in January 1967, anticipating to complete the job within five months. The hotel was not completely demolished until February 1968. In January 1967, Kahn and Jacobs announced that Minskoff's tower, One Astor Plaza, would be 50 stories tall with a facade of stone and tinted glass. The Minskoffs requested zoning amendments to allow the construction of an office building, as well as a modification of the site's
sky exposure plane to maximize the amount of office space that faced Broadway. Consequently, the plans for One Astor Plaza initially did not include a theater. Though Weinstein said he initially remembered "feeling very depressed" at the Minskoffs' tower-with-theater plans, Elliott was "elated", saying: "I think you guys have got your theater". When Weinstein expressed his doubts about the building's floor area, Elliott responded: "Oh, that. That just shows they're ready to negotiate." The proposed legislation would directly allow theaters in One Astor Plaza and the
Uris Building, which would be the first completely new Broadway theaters since the
Mark Hellinger Theatre was completed in 1930. The Minskoffs were allowed to build 47 stories as-of-right, or without any zoning bonuses, but the Minskoffs could add in exchange for building a Broadway theater. and the
New York City Board of Estimate gave final approval to the proposal the next month. As planning progressed, members of the Broadway-theatre industry expressed concerns that theatrical experts had not been consulted in the design of One Astor Plaza's theater. The
Lehman Brothers became partners in One Astor Plaza in March 1968. At the time, the vacant site was being used for parking, since the Minskoffs were requesting city approval for another modification that would allow a movie theater to be built in the basement. The CPC approved the theater over the Shuberts' objections, as did the Board of Estimate. In the meantime, the vacant lot was used in September 1968 for a benefit for the film
Funny Girl, hosted by
Barbra Streisand. Albert W. Selden had tentatively agreed to lease the Broadway theater in One Astor Plaza. The building was to contain across 54 floors, including three restaurants and the two theaters.
Construction Mayor Lindsay attended the
groundbreaking ceremony for One Astor Plaza on October 10, 1968. One Astor Plaza was one of 23 major office projects underway in New York City at the time. During excavation, the contractors bored holes up to deep, then placed dynamite sticks in the holes, covering the openings with blasting mats before detonating the dynamite. As part of an agreement with the Shubert Organization, the blasts did not occur when there were
matinee performances at the Shubert Theatre and other nearby theaters. The 1,562-seat movie theater was leased in January 1969 by
Walter Reade, who also planned to operate the fourth through ninth floors of offices.
Fawcett Publications signed a long-term lease for three floors in One Astor Plaza that February, followed the next month by
Quality Bakers of America's lease of two floors. Work on One Astor Plaza temporarily stopped in July 1969 due to a
labor strike. The project faced some delays due to the inclusion of the Broadway theater at the building's base, as well as rising costs and decreasing demand for office space. Although Minskoff & Sons president Jerome Minskoff had agreed to the theater as "our way of paying the city back", he said this had increased costs by up to 30 percent, from $55 to $70 million. and glass fell from the building during two separate incidents that November, when facade installation was progressing on the lower stories. Several glass panes fell on November 5, and a worker was injured on November 29 when glass panes fell during a heavy wind. but the city's acting buildings commissioner could not find a clear cause for the falling glass. By 1970, a combined of office space was being developed along Broadway in Midtown, much of which stood vacant due to a slowdown in office leasing.
W. T. Grant became the building's largest tenant in December 1970, leasing , including the entire 40th through 53rd floors. In exchange, One Astor Plaza would be formally known as the W. T. Grant Building, and the company's name would be placed in large letters atop the building. Simultaneously, the Minskoffs agreed to pay off the lease on W. T. Grant's existing office space at 1441 Broadway. The next month, the Walter Reade Organization sought to sublet all six floors of its own space.
Bankers Trust leased a bank branch on the second story in March 1971. that rate had increased to 87 percent by the next month.
Completion and early years Fawcett Publications was the first tenant at the building, moving into the 12th through 16th floors The building was planned to be formally renamed that November when W. T. Grant moved in, but the company's relocation into the building was then delayed to mid-1972. Among these issues was Reade's concern that the auditorium needed to be insulated from the adjacent
subway tunnels. Shortly after the building was completed, a window-washing scaffold fell from One Astor Plaza's facade in March 1972, killing two workers. The building's parking garage and three retail stores were leased in early 1972.
Billboard Publications, which leased one floor; and accounting firm Clarence Rainess & Co., which leased one and a half floors. By January 1973, the Minskoff was ready to open, but the basement cinema had not even been furnished yet because of continuing disputes over subway soundproofing. The Minskoff Theatre officially opened on March 13, 1973. Reade ended his lease of the basement movie theater the next month, citing financial difficulties. Further issues concerned the building's valuation, which had been reduced from $45.3 to $40.8 million during 1971–1972; the reduction had been granted because the Minskoffs falsely stated that One Astor Plaza was mostly vacant. The
Loews movie chain leased the basement movie theater in April 1974, One Astor Plaza's anchor tenant W. T. Grant had gone bankrupt by late 1975 and initially planned to downsize to four and a half floors. However, W. T. Grant subsequently decided to leave the building altogether, so the company's signage was removed from One Astor Plaza in March 1976. The third floor was also reconstructed in 1976 to accommodate the Minskoff Recording Studios. The
New York Telephone Company took another four floors in May 1979. By then, most of the building's vacant space had been filled; the other tenants included
CBS and the
New York State Urban Development Corporation (UDC). A theater museum was also being planned for the arcade at the time. One Astor Plaza was fully rented by 1980. Two years later, the
Museum of the City of New York opened a museum in the ground-story arcade, dedicated to the history of Broadway theater. $202 million, or $210 million. The sale included a contract between the Minskoffs and a joint venture of
The Related Companies and
Shearson/
American Express, which in turn sold its contract to Tishman Speyer and Equitable. At the time, the real estate market in New York City was growing, and Equitable had projected that the building would generate $40 million in gross income by 1991. The 25 limited partners, who gave a combined $77 million, were primarily executives at
Bear Stearns. One Astor Plaza needed to be renovated to comply with modern building codes, including the addition of
fire sprinklers and the removal of
asbestos. The average rent for offices at One Astor Plaza was , far below the market rate, but Tishman Speyer and Equitable had planned to upgrade the building and raise rents. Consequently, the Minskoff Recording Studios were nearly evicted in October 1984, The theater museum in the ground-story arcade was closed in 1986 due to low attendance. and they ultimately closed the next year.
Bankruptcy and improvements Tishman Speyer then renovated the lobby and elevators in 1989. The same year,
Viacom International Inc. negotiated to lease several stories in One Astor Plaza for 20 years. The company planned to occupy initially, with an option to expand by another . 1515 Broadway Associates LP filed for
Chapter 11 bankruptcy protection in October 1990, shortly after Tishman Speyer gave up its general-partnership interest. Manufacturers Hanover also claimed that Tishman Speyer's chief executive, Gerald Speyer, had opposed a bankruptcy proceeding. Shortly after the court hearing, Manufacturers Hanover and Equitable agreed to a tentative
settlement in which Equitable would extend a $95 million
line of credit to the limited partners. In exchange, Manufacturers Hanover's lawsuit and Equitable's Chapter 11 filing would be withdrawn. The bankruptcy filing was thus dropped in December 1991. Throughout these legal disputes, Equitable continued to maintain the building's services and attempted to not only retain existing occupants but also attract new tenants by providing favorable concessions. and an existing merchandising tenant expanded its space in the building at a lower rental rate. Additionally, Equitable covered the brokers' fees and tenant-improvement charges for new tenants for several years. Equitable's success in leasing One Astor Plaza was also influenced by the lack of tenants at two newer developments nearby, 1540 and
1585 Broadway, during the early 1990s. Following Viacom's acquisition, Paramount relocated from
15 Columbus Circle to One Astor Plaza, and the expanded Viacom took up 25 floors, housing subsidiaries such as
Nickelodeon and
MTV in the building. Viacom thus became the tower's largest tenant, occupying , with options to take other floors as existing tenants' leases expired. Equitable had been able to remove the asbestos and rent nearly all the space at rates of around . The state UDC, which had occupied nine floors, left the building in the following years as Viacom continued to expand. In September 1997, MTV opened studios at One Astor Plaza's second floor after an $8 million renovation. CBS and Viacom announced in 1999 that they would merge, and Viacom renewed its lease at One Astor Plaza, though the company planned to sell CBS's nearby headquarters, the
CBS Building. By early 2001, Viacom had planned to buy One Astor Plaza in conjunction with its sale of the CBS Building. That August, Equitable hired
Goldman Sachs to market One Astor Plaza; Equitable had rejected an offer to swap One Astor Plaza for the CBS Building directly because the latter building was worth much less. The transaction was ultimately canceled in November 2001. This was attributed in part to Viacom's demand that any buyer first acquire One Astor Plaza and then swap that for the CBS Building and cash; such a transaction would enable Viacom to avoid paying estate transfer taxes on the transaction.
SL Green ownership 2000s In March 2002, a joint venture led by
SL Green Realty acquired One Astor Plaza for approximately $480 million, the city's largest real-estate transaction since the
September 11 attacks. SL Green had a 55 percent ownership stake while its partner SITQ Immobilier (a subsidiary of Canadian pension fund
CDPQ), had the remaining 45 percent. SL Green was required to have terrorism insurance on the building, and the sale demonstrated that large buildings such as One Astor Plaza could obtain such insurance. SL Green chairman
Stephen L. Green considered One Astor Plaza a "core building" to his portfolio but, according to ''
Crain's New York'' magazine, those in the real estate industry believed that Green had overvalued the building. Alliance Building Service, operated by Green's son Gary, was hired to provide cleaning and security services for the building. After acquiring the building, SL Green sought to replace five storefronts on Broadway with one large retailer. SL Green also bought out the lease of the Loews Astor Plaza movie theater and closed it in 2004; By 2008, the downsized Viacom was still the largest office tenant of One Astor Plaza, occupying ; the building only had available for lease. Viacom's leases were scheduled to expire within two years, and the company was moving some divisions elsewhere, including
Comedy Central. extending it by five years. The same year, SL Green also hired KPF to renovate the lobby and facade to make the building compliant with
LEED Silver
green building standards. Though other tenants continued to occupy the building, including law firms, Times Square was no longer appealing to small tenants by then because of the high rents. SL Green refinanced 1515 Broadway for $475 million in 2010, and CDPQ sold its stake in the tower to SL Green the next year. In April 2012, Viacom signed a lease to take over all at 1515 Broadway through 2031, taking the remaining space as other tenants' leases expired. This was the fourth-largest lease in New York City history SL Green also agreed to upgrade 1515 Broadway for Viacom and installed three-story-tall advertising screens on the Times Square facade in 2013; SL Green was looking to sell a minority stake in the building by 2017, and the
China Investment Corporation reportedly expressed interest. That November,
Allianz bought a 43 percent ownership stake and some of the debt in a deal that valued 1515 Broadway at $1.95 billion. At the time, Viacom occupied 85 percent of the building. After
Viacom merged back into
CBS Corporation in 2019, ViacomCBS (later
Paramount Global) retained offices at One Astor Plaza.
CBS News converted part of the MTV Studios space into a studio. Paramount Global fired hundreds of the building's employees in mid-2024. Paramount Global began looking to sublease at 1515 Broadway in 2025 after downsizing its workforce. Paramount merged with
Skydance Media in 2025 to form
Paramount Skydance Corporation, whose corporate headquarters were moved to
Los Angeles.
Caesar's Palace Times Square proposal New York state officials announced in April 2022 that they would issue three
casino licenses in
Downstate New York. Following this announcement, SL Green proposed constructing a casino at 1515 Broadway to attract tourists; the casino would have 992 hotel rooms. In October 2022, SL Green and casino operator
Caesars Entertainment jointly submitted a formal proposal for a casino in the building. The bid was also sponsored by
Roc Nation and mayor
Eric Adams's former chief of staff
Frank Carone. Broadway theatrical trade association
The Broadway League expressed opposition to the casino, while trade union
Actors' Equity Association supported the plan. The project received support from 17 trade unions; the
Wyndham Hotels & Resorts chain; the operators of the
Sony Hall and
Town Hall theaters; and local property owners. If Caesars, SL Green, and Roc Nation received a casino license, SL Green chief executive Marc Holliday stood to earn $10 million. In addition, the partnership planned to spend $250 million on quality-of-life improvements to the surrounding neighborhood, including $5 million for the
Callen-Lorde Community Health Center. It also planned to give $22.5 million to the
West Side Community Fund and sell shares in the casino to small investors. The proposed casino resort would have had 992 hotel rooms and of casino space. A slow environmental review process could have caused the proposed resort to be disqualified as final bids were due by June 2025, but SL Green has stated that they will meet the deadline for the completion of the environmental review. Caesar's submitted their bid for a commercial casino license on June 27, 2025. A few weeks later, renderings were released showing what the interior of the resort may look like if the bid is approved. Holliday continued to advocate for a casino approval. The three licenses ultimately were granted to casinos in
Queens and
the Bronx, and Holliday instead began advocating to convert the building into an entertainment complex with a hotel. == Reception ==
