New York City, the most populous city in the United States, is home to more than 7,000 completed high-rise buildings of at least 115 feet (35 m), of which at least 102 are taller than 650 feet (198 m). The tallest building in New York is One World Trade Center, which rises 1,776 feet (541 m). The 104-story skyscraper also stands as the tallest building in the United States, the tallest building in the Western Hemisphere, and the seventh-tallest building in the world. At 1,550 feet (472 m), Central Park Tower is the second-tallest completed building in the city. It has the highest roof of any building outside Asia, and is the tallest residential building in the world. The third-tallest completed building in the city is 111 West 57th Street. Rising to 1,428 feet (435 m), it is the world's most slender skyscraper. The fourth-tallest is One Vanderbilt. At 1,401 feet (427 m), it is the tallest office building in Midtown. The fifth-tallest is 432 Park Avenue at 1,397 feet (426 m). At 1,250 feet (381 m), the 102-story Empire State Building in Midtown Manhattan, which was finished in 1931, stood as the tallest building in the world from its completion until 1970, when construction on the 1,368-foot (417 m) North Tower of the original World Trade Center surpassed it. It is the tenth-tallest building in the United States, and rises to a pinnacle of 1,454 feet (443 m) including its antenna. The North Tower (the original One World Trade Center), along with its twin the South Tower (the first Two World Trade Center), which was six feet shorter, held this title only briefly as they were both surpassed by construction of the 110-story Willis Tower in Chicago in 1973. The Twin Towers remained the tallest buildings in New York City until they were destroyed in 2001 during the September 11 attacks, leaving the Empire State Building again as the city's tallest building. The new One World Trade Center began construction in 2006; in April 2012 it surpassed the Empire State Building to become the city's tallest. Upon its topping out in May 2013, the 1,776-foot (541 m) One World Trade Center surpassed the Willis Tower to become the tallest building in the United States and the Western Hemisphere. One World Trade Center is part of the redevelopment of the World Trade Center, which also includes the 1,079-foot (329 m) 3 World Trade Center, the 977-foot (298 m) 4 World Trade Center, the 743-foot (226 m) 7 World Trade Center, the approved 900-foot (274 m) 5 World Trade Center, and one partly constructed on-hold building: the 1,350-foot (411 m) 2 World Trade Center. The majority of skyscrapers in New York City are concentrated in Midtown and Downtown Manhattan, although other neighborhoods of Manhattan and the boroughs of Brooklyn, Queens, and the Bronx also contain some high-rises. As of March 2024, there were 317 completed skyscrapers that rose at least 492 feet (150 m) in height, more than any other city in the Western Hemisphere, and third most in the world exceeded only by Hong Kong and Shenzhen.

510 Fifth Avenue, originally the Manufacturers Trust Company Building, is a commercial building at the southwest corner of West 43rd Street and Fifth Avenue in Midtown Manhattan, New York City. Opened in 1954, it is the first bank building in the United States to be built in the International Style. Charles Evans Hughes III and Gordon Bunshaft of Skidmore, Owings & Merrill (SOM) designed the building, along with Roy O. Allen and project manager Patricia W. Swan. The interior was designed by Eleanor H. Le Maire, while Harry Bertoia was hired as an artist for some of the building's artwork. 510 Fifth Avenue was built as a bank for the Manufacturers Trust Company, whose president Horace C. Flanigan wanted the design to be inviting to customers. 510 Fifth Avenue contains four full stories, a penthouse, and a basement. Its facade is made largely of glass walls between mullions made of aluminum. Inside is a circular stainless steel door protecting the original bank vault, which was designed by Henry Dreyfuss. The second story is recessed from the facade, and the floor slabs of the upper stories are carried on four columns, giving the impression that they are floating. The building's height and design was influenced by a lease restriction that prohibited the construction of a taller building on a portion of the site. A smaller penthouse rises above the fourth story. 510 Fifth Avenue was commissioned by Manufacturers Trust in 1944; the original plan was designed by Walker & Gillette and canceled in 1948. Walker & Poor was hired in 1950 to modify the original proposal but were replaced with consulting architect SOM after Bunshaft convinced bank executives that a complete redesign would be cheaper. The building was instantly popular upon its opening, becoming Manufacturers Trust's busiest branch and a tourist attraction in itself. Manufacturers Trust's successor, Chase Bank, sold the building to Tahl-Propp Equities in 2000, and it was purchased by Vornado Realty Trust in 2010. After the Chase branch closed in late 2010, SOM renovated 510 Fifth Avenue and converted it into a commercial structure in 2012. 510 Fifth Avenue's design received critical acclaim upon its completion. Praise was focused particularly on its lightweight facade, ceiling lighting, and visible vault. The design inspired that of other bank buildings erected in the 1950s and 1960s. The building's facade was designated as an official landmark by the New York City Landmarks Preservation Commission (LPC) in 1997, and its interior was similarly designated in 2011, following controversy over the removal of one of Bertoia's artworks.

The Hale Building is an office structure which opened in 1927 at 11 East 44th Street in Midtown Manhattan, New York City. Fred T. Ley & Company built the edifice and Shreve & Lamb were its architects. It was owned by the Eleven East 44th Street Corporation. Hale Building is significant as an important residence for offices on the Lower East Side during the late 1920s and the Great Depression era. The Hale Desk Company leased the 2nd, 3rd, and 4th floors of the Hale Building for use as its primary showrooms and executive offices. The lease, consummated in February 1927, was for a period of fifteen years. It covered approximately 16,000 square feet (1,500 m2) of space.The Hale Building was auctioned and its leasehold acquired on a winning bid of $1,750,000 in April 1936. In a judgment in which Eleven East 44th Street Corporation was the defendant, Continental Bank and Trust Company, trustee and plaintiff, was awarded the Hale Building. A judgment of $909,072 was involved. In 2008, a Brooks Brothers store opened in the Hale Building, and in 2019, it was sold to the company for $106 million.

It is primarily a club for men and women with distinction in literature or the arts. The Century Association was founded by members of New York's Sketch Club; preceding clubs also included the National Academy of Design, the Bread and Cheese Club, and the Column. Traditionally a men's club, women first became active in club life in the early 1900s; the organization began admitting women as members in 1988. Named after the first 100 people proposed as members, the first meeting on January 13, 1847, created the club known as the Century; it was incorporated in 1857. It was first housed at 495 Broadway in Lower Manhattan; the club gradually moved uptown, leading to the club's construction of its current location in 1899. During the Civil War, it became headquarters to the U.S. Sanitary Commission. 134 Centurions served in World War I; 110 served in World War II. The clubhouse, a five-story Palazzo style building, was designed by McKim, Mead & White and built from 1889 to 1891. It became a New York City Landmark in 1967 and was added to the National Register of Historic Places in 1982. It was extensively renovated in the early 1990s, with a fifth floor and terrace constructed in 2009. Members of the club have included artists and writers William Cullen Bryant, Frederic Church, Asher B. Durand, John La Farge, Winslow Homer, Paul Manship, Augustus Saint-Gaudens, Louis Comfort Tiffany, John Quincy Adams Ward, and J. Alden Weir.

P. Morgan, Samuel Morse, and Anson Phelps Stokes.

Meinhard v. Salmon, 164 N.E. 545 (N.Y. 1928), is a widely cited case in which the New York Court of Appeals held that partners in a business owe fiduciary duties to one another where a business opportunity arises during the course of the partnership. The court holds that the fiduciary duty of communication was breached where a partner in a joint venture failed to inform his co-partner of a profitable opportunity that was offered by a third-party who was ignorant of the partnership. Furthermore, the duty of loyalty was breached where the partner appropriated to himself a benefit arising from his status as a partner without allowing his co-partner an opportunity to compete. This holding relates to the doctrine of corporate opportunity.

500 Fifth Avenue is a 60-story, 697-foot-tall (212 m) office building on the northwest corner of Fifth Avenue and 42nd Street in Midtown Manhattan, New York City. The building was designed by Shreve, Lamb & Harmon in the Art Deco style and constructed from 1929 to 1931. 500 Fifth Avenue was designed with a facade of bronze, limestone, and terracotta at the base; it is clad with of brick above the fourth floor. While the lowest four floors contain a decorative exterior, little ornamentation is used above the base. The primary entrance is on Fifth Avenue, and storefronts are located at ground level. Upon its opening, the building contained design features including fast elevators, well-lit office units, and a floor plan that maximized the well-lit office space. The 1916 Zoning Resolution resulted in a structure that incorporated setbacks, resulting in the lower floors being larger than the upper floors. 500 Fifth Avenue was built for businessman Walter J. Salmon Sr. In the 1920s, prior to the building's development, the underlying land had become extremely valuable. Similarly to the much larger Empire State Building nine blocks south, which was constructed simultaneously, 500 Fifth Avenue's construction was highly coordinated. 500 Fifth Avenue opened in March 1931, but the structure garnered relatively little attention after the Empire State Building opened shortly afterward. The building was designated an official city landmark by the New York City Landmarks Preservation Commission in 2010.
