GE Building
30 Rockefeller Plaza (officially the Comcast Building; formerly RCA Building and GE Building) is a skyscraper that forms the centerpiece of Rockefeller Center in the Midtown Manhattan neighborhood of New York City. Completed in 1933, the 66-story, building was designed in the Art Deco style by Raymond Hood, Rockefeller Center's lead architect. 30 Rockefeller Plaza was known for its main tenant, the Radio Corporation of America (RCA), from its opening in 1933 until 1988 and then for General Electric until 2015, when it was renamed for its current owner, Comcast. The building also houses the headquarters and New York studios of television network NBC; the headquarters is sometimes called 30 Rock, a nickname that inspired an NBC sitcom of the same name. The tallest structure in Rockefeller Center, the building is the 28th tallest in New York City and the 60th tallest in the United States. 30 Rockefeller Plaza's massing consists of three parts: the main 66-story tower to the ...

Construction Of Rockefeller Center
The construction of the Rockefeller Center complex in New York City was conceived as an urban renewal project in the late 1920s, spearheaded by John D. Rockefeller Jr. to help revitalize Midtown Manhattan. Rockefeller Center is on one of Columbia University's former campuses and is bounded by Fifth Avenue to the east, Sixth Avenue (Avenue of the Americas) to the west, 48th Street to the south, and 51st Street to the north. The center occupies in total, with some of office space. Columbia University had acquired the site in the early 19th century but had moved to Morningside Heights in Upper Manhattan in the early 1900s. By the 1920s, Fifth Avenue in Midtown Manhattan was a prime site for development. Around that time, the Metropolitan Opera (Met) was looking for a new site for their opera house, and architect Benjamin Wistar Morris decided on the former Columbia site. Rockefeller eventually became involved in the project and leased the Columbia site in 1928 for 87 years. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Buildings In The United States
The world's first skyscraper was built in Chicago in 1885. Since then, the United States has been home to some of the world's tallest skyscrapers. New York City, specifically the borough of Manhattan, notably has the tallest skyline in the country. Nine American buildings have held the title of tallest building in the world. New York City and Chicago have always been the centers of American skyscraper building. The 10-story Home Insurance Building, built in Chicago in 1885, is regarded as the world's first skyscraper; the building was constructed using a novel steel-loadbearing frame which became a standard of the industry worldwide. Since its topping out in 2013, One World Trade Center in New York City has been the tallest skyscraper in the United States. Its spire brings the structure to a symbolic architectural height of , connoting the year the U.S. Declaration of Independence was signed, though the absolute tip (or pinnacle) of the structure is measured at .

National Historic Landmark
A National Historic Landmark (NHL) is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Only some 2,500 (~3%) of over 90,000 places listed on the country's National Register of Historic Places are recognized as National Historic Landmarks. A National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed. Creation of the program Prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. In 1935, Congress passed the Historic Sites Act, which authorized the Interior Secretary authority to formally record and organize historic properties, and to designate properties as having "national historical significance", and gave the Nation ...

New York City Landmarks Preservation Commission
The New York City Landmarks Preservation Commission (LPC) is the New York City agency charged with administering the city's Landmarks Preservation Law. The LPC is responsible for protecting New York City's architecturally, historically, and culturally significant buildings and sites by granting them landmark or historic district status, and regulating them after designation. It is the largest municipal preservation agency in the nation. , the LPC has designated more than 37,000 landmark properties in all five boroughs. Most of these are concentrated in historic districts, although there are over a thousand individual landmarks, as well as numerous interior and scenic landmarks. Mayor Robert F. Wagner Jr. first organized a preservation committee in 1961, and the following year, created the LPC. The LPC's power was greatly strengthened after the Landmarks Law was passed in April 1965, one and a half years after the destruction of Pennsylvania Station. The LPC has been involved ...

Diego Rivera
Diego María de la Concepción Juan Nepomuceno Estanislao de la Rivera y Barrientos Acosta y Rodríguez, known as Diego Rivera (; December 8, 1886 – November 24, 1957), was a prominent Mexican painter. His large frescoes helped establish the mural movement in Mexican and international art. Between 1922 and 1953, Rivera painted murals in, among other places, Mexico City, Chapingo, and Cuernavaca, Mexico; and San Francisco, Detroit, and New York City, United States. In 1931, a retrospective exhibition of his works was held at the Museum of Modern Art in New York; this was before he completed his 27-mural series known as ''Detroit Industry Murals''. Rivera had four wives and numerous children, including at least one natural daughter. His first child and only son died at the age of two. His third wife was fellow Mexican artist Frida Kahlo, with whom he had a volatile relationship that continued until her death. His fourth and final wife was his agent. Due to his importance ...

Man At The Crossroads
''Man at the Crossroads'' (1934) was a fresco by Diego Rivera in New York City's Rockefeller Center. It was originally slated to be installed in the lobby of 30 Rockefeller Plaza, the main building of the center. ''Man at the Crossroads'' showed the aspects of contemporary social and scientific culture. As originally installed, it was a three- paneled artwork. A central panel depicted a worker controlling machinery. The central panel was flanked by two other panels, ''The Frontier of Ethical Evolution'' and ''The Frontier of Material Development'', which respectively represented socialism and capitalism. The Rockefeller family approved of the mural's idea: showing the contrast of capitalism as opposed to communism. However, after the ''New York World-Telegram'' complained about the piece, calling it "anti-capitalist propaganda", Rivera added images of Vladimir Lenin and a Soviet Russian May Day parade in response. When these were discovered, Nelson Rockefeller – at the time a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spandrel
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements. Meaning There are four or five accepted and cognate meanings of the term ''spandrel'' in architectural and art history, mostly relating to the space between a curved figure and a rectangular boundary – such as the space between the curve of an arch and a rectilinear bounding moulding, or the wallspace bounded by adjacent arches in an arcade and the stringcourse or moulding above them, or the space between the central medallion of a carpet and its rectangular corners, or the space between the circular face of a clock and the corners of the square revealed by its hood. Also included is the space under a flight of stairs, if it is not occupied by another flight of stairs. In a building with more than one floor ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setback (architecture)
A setback, in the specific sense of a step-back, is a step-like form of a wall or other building frontage, also termed a recession or recessed storey. Importantly, one or more step-backs lowers the building's center of mass, making it more stable. A setback as a minimum one-bay indent across all storeys is called a recessed bay or recess and is the more common exterior form of an alcove (architecture). Notable upper storeys forming a step-back may form a belvedere – and in residential use are considered the penthouse. If part of the roof, then they are a loft or attic/garret. History Setbacks were used by people to increase the height of masonry structures by distributing gravity loads produced by building materials such as clay, stone, or brick. This was achieved by regularly reducing the footprint of each level located successively farther from the ground. Setbacks also allowed the natural erosion to occur without compromising the structural integrity of the building. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1916 Zoning Resolution
The 1916 Zoning Resolution in New York City was the first citywide zoning code in the United States. The zoning resolution reflected both borough and local interests, and was proposed after the Equitable Building was erected in Lower Manhattan in 1915. The resolution was a measure adopted primarily to stop massive buildings from preventing light and air from reaching the streets below, and established limits in building massing at certain heights, usually interpreted as a series of setbacks and, while not imposing height limits, restricted towers to 25% of the lot size. The chief authors of this resolution were George McAneny and Edward M. Bassett. Impact The 1916 Zoning Resolution had a major impact on urban development in both the United States and internationally. Architectural delineator Hugh Ferriss popularized these new regulations in 1922 through a series of massing studies, clearly depicting the possible forms and how to maximize building volumes.

Massing
Massing is a term in architecture which refers to the perception of the general shape and form as well as size of a building. Massing in architectural theory Massing refers to the structure in three dimensions (form), not just its outline from a single perspective (shape). Massing influences the sense of space which the building encloses, and helps to define both the interior space and the exterior shape of the building. The creation of massing, and changes to it, may be additive (accumulating or repeating masses) or subtractive (creating spaces or voids in a mass by removing parts of it). Massing can also be significantly altered by the materials used for the building's exterior, as transparent, reflective, or layered materials are perceived differently. It is widely accepted that architectural design begins by studying massing. From a distance, massing, more than any architectural detail, is what creates the most impact on the eye. Architectural details or ornaments may serve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
