Context During the 19th century, life insurance firms were some of the first companies to build high-profile skyscrapers. The
Equitable Life Assurance Society of the United States, founded by
Henry Baldwin Hyde in 1859, had built the
Equitable Life Building on 120 Broadway in 1870. The Equitable Life Building was the first office building to feature passenger elevators, and at
a record upon construction, was among the world's first skyscrapers. and in 1887. Equitable assumed control of all properties on the block by 1906. By the 1890s, the Equitable Life Building was architecturally outdated, and
George B. Post prepared plans for a 40-story structure in 1897, which did not proceed. In 1907,
Daniel H. Burnham's company had proposed replacing the Equitable Life Building with a 33-story structure. Burnham's firm filed plans for a 62-story building in 1908, to top the Singer Building and Metropolitan Life Tower. This new building would have had a 34-story base and a 28-story tower, being tall, with of floor area and 3,600 offices. Although bidding for the proposed structure began in December 1908, The plan was ultimately dropped, possibly due to opposition over the building's sheer bulk. Fire engines could not save the structure because the water from the engines had frozen in the cold weather. Equitable quickly set up temporary quarters at the
City Investing Building. Given that the previous building had been worth very little, the land was actually worth more after the fire than beforehand.
Planning and construction Planning After the fire,
Thompson–Starrett was hired to clear the site, and the plot was chosen as the location for Equitable's new headquarters building. and finalized the sale that October for $13.5 million. and Andrews sued du Pont in July 1913, leading du Pont to pay Andrews $100,000 for his involvement. Horowitz then corresponded with Ernest Graham, the other major partner at D. H. Burnham & Company after Burnham's June 1912 death, One group of bankers planned to build a park on the site, a suggestion that Horowitz said "outranks, for nerve, anything of which I ever heard", and was dropped when Horowitz suggested that the group raise $13.5 million to buy out du Pont's ownership share. This plan also failed, On April 12, 1913, du Pont formed the Equitable Office Building Corporation to take title to the building site, and gave Equitable a $20.5 million
mortgage loan to run for 60 years. Equitable would lease three floors in exchange for 9%
dividends in the building corporation, to be paid in perpetuity. Equitable president William A. Day was appointed as chairman of the board of the building corporation. Since there were no nearby material-storage areas, it was imperative that work be completed as quickly as possible. Excavation for the building started in June 1913. The cofferdam around the foundation was initially reinforced with timber cross-bracing until the steel frame underground had been sufficiently completed to support the cofferdam. By January 1914, crews had excavated the foundation and dug to the bedrock below street level. The steel work was built to the second floor using six
derricks; the steel frame above that point was erected using lighter derricks with longer masts and booms. while another died when a crane dropped a girder onto a platform where six men were working. The steel frame reached street level in February 1914. The
cornerstone was officially laid on April 30, 1914, at a ceremony attended by mayor
John Purroy Mitchel. The Equitable Building was the first private construction project in New York City where the mayor attended the cornerstone-laying ceremony. Work on the superstructure officially began on June 10, 1914. Work on the building was completed on February 1, 1915.
Use The Equitable Building was completed on May 1, 1915, The Equitable Society itself occupied , a little more than 10% of the total floor area, on the sixth through eighth floors. Other early lessees included tenants as diverse as
General Electric, the
Federal Reserve Bank of New York, the
Fidelity Trust Company, and
American Smelting & Refining. The Equitable Building was also occupied by industrial concerns such as the
American Can Company,
Kennecott Copper Company,
E. I. du Pont de Nemours,
Goodyear Tire and Rubber Company, and
Aluminum Company of America, as well as railroads such as
Missouri Pacific Railroad,
Union Pacific Railroad, and
Southern Railway. Equitable Life itself only had its home office in the Equitable Building until 1924, when it moved to 393 Seventh Avenue (now
11 Penn Plaza).
1910s through 1930s At the time of its completion, the Equitable Building had 20,000 employees working inside it, and 50,000 additional daily visitors. During the first year of operation, du Pont made $3 million in profit. The building's valuation was increased from $20.5 million to $25 million that year, because of a prosperous realty market at the time. The following year, the Equitable Office Building Corporation applied for a reduction in the building's valuation from $25 million to $18 million, due to foreclosures on other large buildings in New York City. Further devaluation occurred in 1921, when the building was estimated to be worth $11.5 million, but by the next year, the building was re-valued at $30 million, making it among the city's most valuable properties. The edifice was first placed for sale in 1923, with du Pont offering the building for $40 million. In 1925, du Pont sold the Equitable Building for $38.5 million to the New York Empire Company, a subsidiary of the
Brotherhood of Locomotive Engineers and Trainmen. The next year, the Brotherhood sold the building to a syndicate composed of
William Henry Vanderbilt, Harry C. Cushing III, and Leroy W. Baldwin for $40 million. By 1928, the Equitable Building was assessed at $31 million, making it the highest-valued building in New York City.
1940s through 1960s By the 1940s, the Equitable Office Building Corporation was in poor financial shape. Bankruptcy proceedings started in 1940, but were delayed due to
World War II; three potential investors submitted dueling proposals in 1946. The building was refinanced in 1947, receiving a first-mortgage loan of $14.5 million, among the largest ever in New York City's history. At this time, Equitable Life sold the mortgage on the tower.
Lawrence Wien bought the lease for the land in 1956, though Webb and Knapp retained ownership of the building as well as its operating sublease. By then, Equitable was planning to build the new
1285 Avenue of the Americas on
Sixth Avenue between 51st and 52nd streets in
Midtown Manhattan. Two years later, the Equitable Life Assurance Company bought the building outright, as part of a $25 million exchange wherein Webb and Knapp bought the Sixth Avenue plot. In addition, Wien assumed the building's operating sublease the same year. Equitable moved to 1285 Avenue of the Americas in 1961 from its previous home office at 393 Seventh Avenue.
1970s to present The building was designated a
National Historic Landmark in 1978.
Silverstein Properties purchased the Equitable Building in 1980 for $60 million, in partnership with five pension funds whose mortgage nearly covered the purchase price. After buying the building,
Larry Silverstein renovated and restored it at a cost of $30 million, The renovation was completed in 1990. As a result of the project, occupancy rates increased from 60% in 1991 to 80% in 1993. Following the
early 1990s recession, Silverstein sold his ownership stake and leased the Equitable Building, though Silverstein Properties bought it back in 1999. The
New York City Landmarks Preservation Commission designated the Equitable Building a
New York City landmark in 1996. In 2017, Silverstein announced another round of renovations, which cost $50 million and were undertaken by
Beyer Blinder Belle. The renovation was completed in July 2019. Several murals resembling street art were installed on the third floor in November 2019. Tenants include the
New York City Department of City Planning,
Macmillan Publishers, architecture firm
Beyer Blinder Belle, the
Securities Industry and Financial Markets Association, the
New York City Housing Development Corporation, and
Tower Research Capital. == Notable incidents ==
