The tower rises 24 floors and 320 feet (98 m) in height. Owned by DPC Companies and Bridge Commercial Real Estate, 3200 N Central was built in 1985. Upon completion it stood as the sixth-tallest building in Phoenix, and today it stands as
212-500: A Built-up area (BUA) as an area of built-up land of at least 20 hectares (0.077 sq mi), separated from other settlements by at least 200 metres (660 ft). For 2011 census data there are 5,493 built-up areas, of which 501 are divided into Built-up area sub-divisions (BUASD) for which data is also available. Each built-up area is named algorithmically, using Ordnance Survey place-name data. The ONS has produced census results from urban areas since 1951, since 1981 based upon
318-565: A 45-degree angle cut into each of the four corners. 3200 N Central is designed in the Post Modern style. It features exterior columns and spandrels giving the tower an angular, repetitive appearance. The top floor plate is smaller than the rest of the tower and features a balcony, which rings the outer perimeter with the exception of its 45-degree corners.

Residential tower complexes are common in Asian countries such as China, India, Bangladesh, Indonesia, Taiwan, Singapore, Japan, Pakistan, Iran and South Korea, as urban densities are very high. In Singapore and urban Hong Kong , land prices are so high that a large portion of the population lives in high-rise apartments. In fact, over 60% of Hong Kong residents live in apartments, many of them condominiums . Of them in 2020, 2,112,138 were identified residents of public housing, which

There were 2,646 urban areas identified by the Census Bureau for 2020. 511 of these had a population of 50,000 or more. For the 2000 and 2010 censuses, the Census Bureau differentiated between two kinds of urban areas: urbanized areas and urban clusters. The term urbanized area denoted an urban area of 50,000 or more people. Urban areas under 50,000 people were called urban clusters . Urbanized areas were first delineated in

Places administered by
848-547: A design with setbacks . Apartment buildings have technical and economic advantages in areas of high population density , and have become a distinctive feature of housing accommodation in virtually all densely populated urban areas around the world. In contrast with low-rise and single-family houses, apartment blocks accommodate more inhabitants per unit of area of land and decrease the cost of municipal infrastructure . Various bodies have defined "high-rise": High-rise apartment buildings had already appeared in antiquity :
954-499: A different section in the building regulations in the world. The residential tower block with its typical concrete construction is a familiar feature of Modernist architecture . Influential examples include Le Corbusier 's "housing unit", his Unité d'Habitation , repeated in various European cities starting with his Cité radieuse in Marseille (1947–52), constructed of béton brut , rough-cast concrete , as steel for framework
1060-446: A greater demand for housing. However, some cities such as Quebec City and Halifax have fewer high-rise buildings due to several factors: a focus on historic preservation , height restrictions, and lower growth rates. In middle-sized cities with a relatively low population density, such as Calgary , Edmonton , Winnipeg , or Hamilton there are more apartment towers but they are greatly outnumbered by single-family houses . Most of

There are two measures of
1696-572: A municipal corporation, cantonment board or notified town area committee are automatically considered urban areas. The Census of India 2011 also defined the term "urban agglomeration" as an integrated urban area consisting of a core town together with its "outgrowths" (contiguous suburbs). In Pakistan , an area is a major city and municipality if it has more than 100,000 inhabitants according to census results. Cities include adjacent cantonments . Urbanisation in Pakistan has increased since

Mexico is one of many countries where the urbanization rate is at least 80%. Mexico City , its capital, is the largest urban area in the country. In the United States , the Census Bureau defines urban areas and delineates urban area boundaries after each census. The Bureau defines an urban area as "a statistical geographic entity consisting of
2014-765: A small scale. There are some tall residential buildings in La Défense district, such as Tour Défense 2000 , even though the district is mainly "commercial". This allows the residents to walk to the nearby office buildings without using vehicles. Tower blocks were first built in the United Kingdom after the Second World War , and were seen as a cheap way to replace 19th-century urban slums and war-damaged buildings. They were originally seen as desirable, but quickly fell out of favour as tower blocks attracted rising crime and social disorder, particularly after
2120-418: A solution for housing, especially for public housing , reaching a peak of popularity in the 1960s with the introduction of prefabrication technology . By the early 1970s, opposition to this style of towers mounted, with many, including urban planners, now referring to them as " ghettos ". Neighbourhoods like St. James Town were originally designed to house young "swinging single" middle class residents, but
2226-409: A suburb of another urban area rather than as a self-contained urban entity, or is geographically remote from other urban communities. Accordingly, the new definition set out three distinct types of population centres: small (population 1,000 to 29,999), medium (population 30,000 to 99,999) and large (population 100,000 or greater).

Tall residential towers are a staple building type in all large cities. Their relative prominence in Canadian cities varies substantially, however. In general, more populated cities have more high-rises than smaller cities, due to a relative scarcity of land and
3180-602: Is no clear difference between a tower block and a skyscraper, although a building with forty or more stories and taller than 150 metres (490 ft) is generally considered a skyscraper. High-rise structures pose particular design challenges for structural and geotechnical engineers, particularly if situated in a seismically active region or if the underlying soils have geotechnical risk factors such as high compressibility or bay mud . They also pose serious challenges to firefighters during emergencies in high-rise structures. New and old building design, building systems such as

Statistics New Zealand defines urban areas in New Zealand, which are independent of any administrative subdivisions and have no legal basis. There are four classes of urban area: major urban areas (population 100,000+), large urban areas (population 30,000–99,999), medium urban areas (population 10,000–29,999) and small urban areas (population 1,000–9,999). As of 2021, there are 7 major urban areas, 13 large urban areas, 22 medium urban areas and 136 small urban areas. Urban areas are reclassified after each New Zealand census , so population changes between censuses does not change an urban area's classification. According to Statistics Canada , an urban area in Canada

Separate areas are linked if less than 200 m (220 yd) apart. Included are transportation features. The UK has five Urban Areas with a population over a million and a further sixty nine with a population over one hundred thousand . The Australian Bureau of Statistics refers to urban areas as Urban Centres, which it generally defines as population clusters of 1,000 or more people. Australia
7314-581: The fall of the Berlin Wall, and some in buildings that survived World War II. In Western Europe, there are fewer high-rise buildings because of the historic city centres. In the 1960s, developers began demolishing older buildings to replace them with modern high-rise buildings. In Brussels there are numerous modern high-rise buildings in the Northern Quarter business district. The government of Belgium wants to recreate Washington, D.C. , on
7420-608: The former Eastern Bloc countries, tower blocks built during the Soviet years make up much of the current housing estates and most of them were built in the specific socialist realist style of architecture that was dominant in the territories east of the Iron Curtain : blocky buildings of that era are colloquially known as Khrushchyovka . However, there were also larger and more ambitious projects built in Eastern Europe at
7526-596: The forms of Weilongwu (围龙屋) and Tulou (土楼), the latter are large, enclosed and fortified earth building, between three and five stories high and housing up to 80 families. The oldest still standing tulou dates back from the 14th century. High-rises were built in the Yemeni city of Shibam in the 16th century. The houses of Shibam are all made out of mud bricks , but about five hundred of them are tower houses , which rise five to sixteen stories high, with each floor having one or two apartments . This technique of building
7632-403: The globe, a global definition is not possible. European countries define urbanized areas on the basis of urban-type land use , not allowing any gaps of typically more than 200 metres (220 yd), and use satellite imagery instead of census blocks to determine the boundaries of the urban area. In less-developed countries , in addition to land use and density requirements, a requirement that
7738-561: The highest floor was common in the building regulations at the time and it is still so today in Germany. The common height for turntable ladders did later go to 32 meters (100 feet), so that 30 meter is a common limit in some building regulations today, for example in Switzerland. Any building that exceeds the height of the usual turntable ladders in a city must install additional fire safety equipment, so that these high-rise buildings have
7844-465: The island of Great Britain , but taller high-rises are generally more common than in the Republic of Ireland. Most tower blocks and flat complexes are found in Belfast , although many of these have been demolished since the 1990s and replaced with traditional public housing units . The mid-rise Divis flats complex in west Belfast was built between 1968 and 1972. It was demolished in the early 1990s after
7950-494: The land area is counted. The Randstad is the country's largest conurbation located in the west of the country and contains the four largest cities: Amsterdam, Rotterdam , The Hague , and Utrecht . The Randstad has a population of 7 million inhabitants and is the 6th largest metropolitan area in Europe. Norway defines urban areas ("tettsteder") similarly to the other Nordic countries . Unlike in Denmark and Sweden,
8056-525: The largest city by land area on the European continent. Saint Petersburg , the cultural capital, is the second-largest city, with a population of roughly 5.4 million inhabitants. Other major urban areas are Yekaterinburg , Novosibirsk , Kazan , Nizhny Novgorod , and Chelyabinsk . Spain is a very highly urbanized country. Madrid is its largest urban area. The Southern and Eastern coasts with Barcelona , Valencia and Málaga are more urbanised than
8162-664: The largest residential towers in Canada are found in Montreal , Toronto , and Vancouver ; the country's most densely populated cities. Toronto contains the second largest concentration of high-rise apartment buildings in North America (after New York). In Canada, like in other New World countries, but unlike Western Europe, most high-rise towers are located in the city centre (or "downtown"), where smaller, older buildings were demolished to make way in redevelopment schemes. In
8268-617: The largest urban area in the country. According to the United Nations Economic and Social Commission for Asia and the Pacific , the country has the highest urbanised population in Southeast Asia, with 100 percent of its population living in an urban area. The Urban Redevelopment Authority (URA) is responsible for the urban land-use planning, which designates land use and urban density of the country. The country
8374-612: The likelihood of taller insulae collapsing. The lower floors were typically occupied by either shops or wealthy families, while the upper stories were rented out to the lower classes. Surviving Oxyrhynchus Papyri indicate that seven-story buildings even existed in provincial towns, such as in third century AD Hermopolis in Roman Egypt . In Arab Egypt , the initial capital city of Fustat housed many high-rise residential buildings, some seven stories tall that could reportedly accommodate hundreds of people. Al-Muqaddasi , in
8480-422: The major cities, returning home to the countryside periodically with their earnings. China has more cities with one million or more long-term residents than any other country, including the three global cities of Beijing , Hong Kong, and Shanghai ; by 2025, the country will be home to 221 cities with over a million inhabitants. The figures in the table below are from the 2008 census, and are only estimates of
8586-513: The majority of the world's population lived in a city. By that time a high estimate calculated up to 3.5 million square kilometers of land were urban, estimates ranging from 1% of global land area. In 2014 there were 7.3 billion people living on the planet, of which the global urban population comprised 3.9 billion. The Population Division of the United Nations Department of Economic and Social Affairs at that time predicted
8692-543: The most urbanised nation in South Asia. Furthermore, 50% of Pakistanis live in towns of 5,000 people or more. Karachi is the most populated city in Pakistan closely followed by Lahore according to the 2017 Census . In Bangladesh , there are total 532 urban areas, which are divided into three categories. Those are City Corporation , Municipal Corporation (Pourasova) and Upazila town . Among those urban areas, Dhaka
8798-437: The new term " population centre "; the new term was chosen in order to better reflect the fact that urban vs. rural is not a strict division, but rather a continuum within which several distinct settlement patterns may exist. For example, a community may fit a strictly statistical definition of an urban area, but may not be commonly thought of as "urban" because it has a smaller population, or functions socially and economically as
8904-573: The north of the city, the iconic seven-tower complex in the New Lodge remains, although so too the problems that residents face, such as poor piping and limited sanitation. Farther north, the four tower blocks in Rathcoole dominate the local skyline, while in south Belfast, the tower blocks in Seymour Hill, Belvoir and Finaghy remain standing. Most of the aforementioned high-rise flats in
9010-723: The now demolished Unity Flats and the Weetabix Flats in the Shankill area), New Lodge was its only high-rise project in the inner city; there were three more in outlying areas of the city during the 1960s, two being in Mount Vernon in North Belfast and one being in the Clarawood estate, East Belfast. The Royal Hospital built three thirteen-story towers for use as staff accommodation, prominently located adjacent to
9116-782: The ongoing changes made to postwar housing estates since the 2000s in former communist countries vary – ranging from simply applying a new coat of paint to the previously grey exterior to thorough modernisation of entire buildings. In the European Union , among former Warsaw Pact states, a majority of the population lives in flats in Latvia (65.1%), Estonia (63.8%), Lithuania (58.4%), Czech Republic (52.8%), and Slovakia (50.3%) (as of 2014 , data from Eurostat ). However, not all flat dwellers in Eastern Europe live in Cold War-era blocks of flats; many live in buildings constructed after
9222-530: The other hand, the Katowice urban area with numerous large and medium cities covers 1,468 km and has above 2 million people. The metropolitan areas in Poland are the biggest urban zones (e.g. Katowice metropolitan area , Łódź metropolitan area and Szczecin metropolitan area ) and have great impact on the rural surroundings, as it is around Lublin , Radom , Kielce , Tarnów and Białystok . Moscow ,
9328-546: The population increased considerably, tower blocks have become more common. This time, however, the new tower blocks integrated shopping malls, parking systems, and other convenient facilities. Samsung Tower Palace in Seoul , South Korea, is the tallest apartment complex in Asia. In Seoul, approximately 80 percent of its residents live in apartment complexes which comprise 98 percent of recent residential construction. Seoul proper
9434-409: The residents demanded new houses due to mounting problems with their flats. Divis Tower , built separately in 1966, still stands, however; and in 2007 work began to convert the former British Army base at the top two floors into new dwellings. Divis Tower was for several decades Ireland's tallest residential building, having since being surpassed by the privately owned Obel Tower in the city centre. In
9540-505: The second floor", accomplished by folding concrete floor planes (like "bamboo mats," claims the firm), so that every third story opens into a private courtyard. In the larger towers, the two-story units are stacked slightly askew, adding to the visual interest of the variegated façades (Goldhagen 2012)." Housing in Japan includes various traits coming from different eras. The word danchi now either means an employer-provided housing or has
9646-669: The skyline, comfortable private spaces and attractive public spaces. None of these "functional, handsome, and humane high-rise residential buildings" are affordable housing . The 2012 Pritzker Prize was awarded to Chinese architect Wang Shu. Among his winning designs is the Vertical Courtyard Apartments, six 26-story towers by his architectural firm Amateur Architecture Studio built in Hangzhou. "These towers were designed to house two-story apartments, in which every inhabitant would enjoy "the illusion of living on
9752-674: The tallest high-rise apartment building in the world is the Central Park Tower on Billionaires' Row in Midtown Manhattan , towering at 1,550 feet (470 m). Streets in the sky is a style of architecture that emerged in Britain in the 1960s and 1970s. Generally built to replace run-down terraced housing , the new designs included not only modern improvements such as inside toilets , but also shops and other community facilities within high-rise blocks. Examples of

During 1990–2008, city dwellers made up 36% of Pakistan's population, making it
9964-473: The time, which have since become recognisable examples of post-war modernism ; such as the largest falowiec building in the Przymorze Wielkie district of Gdańsk , with a length of 860 m (2,821.52 ft) and 1,792 flats, it is the second longest housing block in Europe. In Romania , the mass construction of standardised housing blocks began in the 1950s and 1960s with the outskirts of
10070-470: The urban population would occupy 68% of the world population by 2050, with 90% of that growth coming from Africa and Asia. Urban areas are created and further developed by the process of urbanization. They are measured for various purposes, including analyzing population density and urban sprawl . Urban areas are also mostly found in the United States , Canada , Brazil , Mexico , Argentina , Chile , Japan and Australia and many other countries where
10176-492: The urban populations within administrative city limits; a different ranking exists when considering the total municipal populations (which includes suburban and rural populations). The large " floating populations " of migrant workers make conducting censuses in urban areas difficult; the figures below include only long-term residents. In Japan , urbanized areas are defined as contiguous areas of densely inhabited districts (DIDs) using census enumeration districts as units with
10282-435: The urbanization rate is over 80%. Unlike an urban area, a metropolitan area includes not only the urban area, but also satellite cities plus intervening rural land that is socio-economically connected to the urban core city, typically by employment ties through commuting , with the urban core city being the primary labor market. The concept of an "urban area" as used in economic statistics should not be confused with
10388-474: The urbanized area of that city are often not the same. For example, the city of Greenville, South Carolina has a city population just over 68,000 and an urbanized area population of around 400,000, while Greensboro, North Carolina has a city population just over 285,000 and an urbanized area population of around 300,000 — meaning that Greenville is actually "larger" for some intents and purposes, but not for others, such as taxation, local elections, etc. In
10494-401: The world's 7.3 billion people that lived in urban areas. The change was driven by a combination of increased total population and increased percent of population living in urban areas. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural areas (3.41 billion), and since then the world has become more urban than rural. This was the first time that
10600-592: The world's tallest skyscraper. However, with the movements of Postmodernism , New Urbanism , and New Classical Architecture , that established since the 1980s, a more classical approach came back to global skyscraper design, that is popular today. Other contemporary styles and movements in high-rise design include organic , sustainable , neo-futurist , structuralist , high-tech , deconstructivist , blob , digital , streamline , novelty , critical regionalist , vernacular , Art Deco (or Art Deco Nouveau ), and neohistorist , also known as revivalist . Currently,
10706-504: The worst reputations of any British social housing schemes and were marred by numerous design and practical problems. The ideal of Streets in the Sky often did not work in practice. Unlike an actual city street, these walkways were not thoroughfares, and often came to a dead end multiple storeys above the ground. They lacked a regular flow of passers-by, and the walkways and especially the stairwells could not be seen by anyone elsewhere, so there
10812-620: Was dominated by large numbers of high-rising urban towers, which fulfilled defensive but also representative purposes. The residential Towers of Bologna numbered between 80 and 100 at a time, the largest of which still rise to 97.2 m. In Florence , a law of 1251 decreed that all urban buildings should be reduced to a height of less than 26 m, the regulation immediately put into effect. Even medium-sized towns such as San Gimignano are known to have featured 72 towers up to 51 m in height. The Hakka people in southern China have adopted communal living structures designed to be easily defensible in

The city has the tallest mud buildings in the world, some more than 30 meters (100 feet ) high. Shibam has been called "one of the oldest and best examples of urban planning based on the principle of vertical construction" or " Manhattan of
11024-473: Was no deterrent to crime and disorder. There were no "eyes on the street" as advocated by Jane Jacobs in her book The Death and Life of Great American Cities . The Unité d'Habitation in Marseille provides a more successful example of the concept, with the fifth floor walkway including a shop and café. Towers in the park is a morphology of modernist high-rise apartment buildings characterized by
11130-771: Was partly caused by council ignorance, as a local action group complained to the council about the fire hazards of the tower several years before the incident, yet remedial work had not been carried out. This fire further made tower blocks less desirable to British residents. There are old high-rise buildings built in the 1960s and 1970s in areas of London such as Tower Hamlets , Newham , Hackney , and virtually any area in London with council housing . Some new high-rises are being built in areas such as Central London , Southwark , and Nine Elms . In east London, some old high-rises are being gentrified, in addition to new high-rises being built in areas such as Stratford and Canary Wharf . The majority of residential high-rise buildings in
11236-457: Was unavailable in post-war France. Residential tower blocks became standard in housing urban populations displaced by slum clearances and " urban renewal ". High-rise projects after World War II typically rejected the classical designs of the early skyscrapers , instead embracing the uniform international style ; many older skyscrapers were redesigned to suit contemporary tastes or even got demolished - such as New York's Singer Building , once
