New York has architecturally noteworthy buildings in a wide range of styles and from distinct time periods, from the saltbox style Pieter Claesen Wyckoff House in Brooklyn, the oldest section of which dates to 1656, to the modern One World Trade Center, the skyscraper at Ground Zero in Lower Manhattan and the most expensive office tower in the world by construction cost.
Manhattan’s skyline, with its many skyscrapers, is universally recognized, and the city has been home to several of the tallest buildings in the world. As of 2011, New York City had 5,937 high-rise buildings, of which 550 completed structures were at least 330 feet (100 m) high, both second in the world after Hong Kong, with over 50 completed skyscrapers taller than 656 feet (200 m). These include the Woolworth Building, an early example of Gothic Revival architecture in skyscraper design, built with massively scaled Gothic detailing; completed in 1913, for 17 years it was the world’s tallest building.

The 1916 Zoning Resolution required setbacks in new buildings and restricted towers to a percentage of the lot size, to allow sunlight to reach the streets below. The Art Deco style of the Chrysler Building (1930) and Empire State Building (1931), with their tapered tops and steel spires, reflected the zoning requirements. The buildings have distinctive ornamentation, such as the eagles at the corners of the 61st floor on the Chrysler Building, and are considered some of the finest examples of the Art Deco style. A highly influential example of the international style in the United States is the Seagram Building (1957), distinctive for its façade using visible bronze-toned I-beams to evoke the building’s structure. The Condé Nast Building (2000) is a prominent example of green design in American skyscrapers and has received an award from the American Institute of Architects and AIA New York State for its design.

The character of New York’s large residential districts is often defined by the elegant brownstonerowhouses and townhouses and shabby tenements that were built during a period of rapid expansion from 1870 to 1930. In contrast, New York City also has neighborhoods that are less densely populated and feature free-standing dwellings. In neighborhoods such as Riverdale (in the Bronx), Ditmas Park (in Brooklyn), and Douglaston (in Queens), large single-family homes are common in various architectural styles such as Tudor Revival and Victorian.
Stone and brick became the city’s building materials of choice after the construction of wood-frame houses was limited in the aftermath of the Great Fire of 1835. A distinctive feature of many of the city’s buildings is the wooden roof-mounted water towers. In the 1800s, the city required their installation on buildings higher than six stories to prevent the need for excessively high water pressures at lower elevations, which could break municipal water pipes. Garden apartments became popular during the 1920s in outlying areas, such as Jackson Heights.
