84-540: Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation , leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be

168-705: A big part of the regular maintenance required. Systems for transport of people within buildings: Systems for transport of people between interconnected buildings: Buildings may be damaged during construction or during maintenance. They may be damaged by accidents involving storms, explosions, subsidence caused by mining, water withdrawal or poor foundations and landslides. Buildings may suffer fire damage and flooding. They may become dilapidated through lack of proper maintenance, or alteration work improperly carried out. High-rise building A tower block , high-rise , apartment tower , residential tower , apartment block , block of flats , or office tower

252-403: A certain general amount of internal infrastructure to function, which includes such elements like heating / cooling, power and telecommunications, water and wastewater etc. Especially in commercial buildings (such as offices or factories), these can be extremely intricate systems taking up large amounts of space (sometimes located in separate areas or double floors / false ceilings) and constitute

336-484: A certain height, a tower can be made with the supporting structure with parallel sides. However, above a certain height, the compressive load of the material is exceeded, and the tower will fail. This can be avoided if the tower's support structure tapers up the building. A second limit is that of buckling—the structure requires sufficient stiffness to avoid breaking under the loads it faces, especially those due to winds. Many very tall towers have their support structures at

420-632: A collective society, an environment suitable and necessary for the new way of life. 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

504-547: 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 :

588-494: 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

672-511: A feature on top of a larger structure or building. Old English torr is from Latin turris via Old French tor . The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean language, connected with the Illyrian toponym Βου-δοργίς. With the Lydian toponyms Τύρρα, Τύρσα, it has been connected with the ethnonym Τυρρήνιοι as well as with Tusci (from *Turs-ci ),

756-446: 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

840-409: A group of inter-related (and possibly inter-connected) builds are referred to as a complex – for example a housing complex , educational complex, hospital complex, etc. The practice of designing, constructing, and operating buildings is most usually a collective effort of different groups of professionals and trades . Depending on the size, complexity, and purpose of a particular building project,

924-566: A high-rise building surrounded by a swath of landscaped land; e.g., the tower does not directly front the street. It is based on an ideology popularised by Le Corbusier with the Plan Voisin , an expansion of the Garden city movement aimed at reducing the problem of urban congestion. It was introduced in several large cities across the world, notably in North America , Europe and Australia as

The International Energy Agency released a publication that estimated that existing buildings are responsible for more than 40% of the world's total primary energy consumption and for 24% of global carbon dioxide emissions. Any building requires

1092-455: A lot more mainly throughout the north and south inner city of Dublin. Suburban flat complexes were built exclusively on the northside of the city in Ballymun , Coolock and Kilbarrack . These flats were badly affected by a heroin epidemic that hit working-class areas of Dublin in the 1980s and early 1990s. Residential tower blocks were previously uncommon outside of Dublin, but during the era of

1176-458: A meaning similar to " projects ". For modern hi-rises, there are two borrowed words to make a distinction: In South Korea, the tower blocks are called Apartment Complex ( 아파트 단지 ). The first residential towers began to be built after the Korean War . The South Korean government needed to build many apartment complexes in the cities to be able to accommodate the citizens. In the 60 years since, as

1260-744: 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

1344-418: 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

1428-711: A target (see siege tower ). Today, strategic-use towers are still used at prisons, military camps, and defensive perimeters. By using gravity to move objects or substances downward, a tower can be used to store items or liquids like a storage silo or a water tower , or aim an object into the earth such as a drilling tower . Ski-jump ramps use the same idea, and in the absence of a natural mountain slope or hill, can be human-made. In history, simple towers like lighthouses , bell towers , clock towers , signal towers and minarets were used to communicate information over greater distances. In more recent years, radio masts and cell phone towers facilitate communication by expanding

1512-667: Is 28% of the total population. Sarah Williams Goldhagen (2012) celebrated the work of innovative architecture firms such as WOHA (based in Singapore), Mass Studies (based in Seoul), Amateur Architecture Studio (based in Hangzhou, China ), and the New York City-based Steven Holl in the transformation of residential towers into "vertical communities" or "vertical cities in the sky" providing aesthetic, unusually designed silhouettes on

1596-624: Is a matter of debate, but generally three stories or less is considered low-rise. There is clear evidence of homebuilding from around 18,000 BC. Buildings became common during the Neolithic period . Single-family residential buildings are most often called houses or homes . Multi-family residential buildings containing more than one dwelling unit are called duplexes or apartment buildings . Condominiums are apartments that occupants own rather than rent . Houses may be built in pairs ( semi-detached ) or in terraces, where all but two of

1680-496: Is a tall building , as opposed to a low-rise building and is defined differently in terms of height depending on the jurisdiction . It is used as a residential , office building , or other functions including hotel , retail , or with multiple purposes combined. Residential high-rise buildings are also known in some varieties of English, such as British English , as tower blocks and may be referred to as MDUs , standing for multi-dwelling units . A very tall high-rise building

1764-638: Is also sometimes used to refer to firefighting equipment with an extremely tall ladder designed for use in firefighting/rescue operations involving high-rise buildings. Building A building or edifice is an enclosed structure with a roof and walls , usually standing permanently in one place, such as a house or factory . Buildings come in a variety of sizes , shapes , and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige , and aesthetic reasons. To better understand

1848-450: Is individually owned; they may be called low-rise (or walk-up ), mid-rise , high-rise , or skyscraper depending on their height. 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

1932-602: 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

2016-545: Is noted for its population density , eight times greater than Rome , though less than Manhattan and Paris. Its metropolitan area is the densest in the OECD . Although some Central and Eastern European countries during the interwar period , such as the Second Polish Republic , already started building housing estates that were considered to be of a high standard for their time, many of these structures perished during

2100-481: Is one in which at least one business is based and people do not live. Examples include stores , restaurant , and hotels . Industrial buildings are those in which heavy industry is done, such as manufacturing . These edifices include warehouses and factories . Agricultural buildings are the outbuildings , such as barns located on farms . Some buildings incorporate several or multiple different uses, most commonly commercial and residential. Sometimes

2184-428: Is referred to as a skyscraper . High-rise buildings became possible to construct with the invention of the elevator (lift) and with less expensive, more abundant building materials. The materials used for the structural system of high-rise buildings are reinforced concrete and steel . Most North American –style skyscrapers have a steel frame , while residential blocks are usually constructed of concrete. There

2268-1297: Is usually a response to high ground prices resulting from the desire of many people to live close to their places of employment or similar attractors. Terms for residential buildings reflect such characteristics as function (e.g., holiday cottage (vacation home) or timeshare if occupied seasonally); size ( cottage or great house ); value ( shack or mansion ); manner of construction ( log home or mobile home ); architectural style ( castle or Victorian ); and proximity to geographical features ( earth shelter , stilt house , houseboat , or floating home). For residents in need of special care, or those society considers dangerous enough to deprive of liberty , there are institutions ( nursing homes , orphanages , psychiatric hospitals , and prisons ) and group housing ( barracks and dormitories ). Historically, many people lived in communal buildings called longhouses , smaller dwellings called pit-houses , and houses combined with barns, sometimes called housebarns . Common building materials include brick, concrete, stone, and combinations thereof. Buildings are defined to be substantial, permanent structures. Such forms as yurts and motorhomes are therefore considered dwellings but not buildings . A commercial building

2352-585: The insulae in Ancient Rome and several other cities in the Roman Empire , some of which might have reached up to ten or more stories, one reportedly having 200 stairs. Because of the destruction caused by poorly built high-rise insulae collapsing, several Roman emperors , beginning with Augustus (r. 30 BC – 14 AD), set limits of 20–25 metres (66–82 ft) for multi-story buildings, but met with limited success, as these limits were often ignored despite

2436-520: The Celtic Tiger the largest cities such as Dublin, Cork , Limerick and Galway witnessed new large apartment building, although their heights have generally been restricted. Some large towns such as Navan , Drogheda , Dundalk and Mullingar have also witnessed the construction of many modern apartment blocks. Tower blocks in Northern Ireland were never built to the frequency as in cities on

2520-539: The Czech Republic and Slovakia ), panelák building under Marxism–Leninism resulted from two main factors: the postwar housing shortage and the ideology of the ruling party . In Eastern European countries, opinions about these buildings vary greatly, with some deeming them as eyesores on their city's landscape while others glorify them as relics of a bygone age and historical examples of unique architectural styles (such as socialist realism, brutalism , etc.). Since

Under the Soviet urban planning ideologies of the 1920s , residential complexes—compact territories with residential dwellings, schools, shops, entertainment facilities, and green spaces —started to prevail in urban planning practice, as they allowed for more careful and efficient planning of the rapid urban expansion. These complexes were seen as an opportunity to build

Some of the earliest surviving examples are the broch structures in northern Scotland , which are conical tower houses . These and other examples from Phoenician and Roman cultures emphasised the use of a tower in fortification and sentinel roles. For example, the name of the Moroccan city of Mogador , founded in

3024-704: The Divis estate were of poor build quality and were all demolished by the early 1990s. Similar slab blocks were built by the NIHT in East Belfast (Tullycarnet) and Derry's Bogside area, all four of which have been demolished. Belfast Corporation constructed seven tower blocks on the former Victoria Barracks site in the New Lodge district. While the Corporation built some mid-rise flats as part of slum clearance schemes (most notably

3108-629: The Greek and Latin names for the Etruscans (Kretschmer Glotta 22, 110ff.) Towers have been used by humankind since prehistoric times. The oldest known may be the circular stone tower in walls of Neolithic Jericho (8000 BC). Some of the earliest towers were ziggurats , which existed in Sumerian architecture since the 4th millennium BC. The most famous ziggurats include the Sumerian Ziggurat of Ur , built in

3192-655: The M2 Motorway at Broadway. Belfast City Hospital also constructed a high-rise slab block which since privatisation has been named Bradbury Court, formerly known as Erskine House. Queens University Belfast built several eleven storey towers at its Queens Elms student accommodation. Of the three sixteen-story point blocks of Larne Borough Council in the late 1960s, only one remains. In Canada, large multi-family buildings are usually known as apartment buildings or apartment blocks if they are rented from one common landowner, or condominiums or condo towers if each dwelling unit

3276-796: The Republic of Ireland were concentrated in the suburb of Ballymun , Dublin . The Ballymun Flats were built between 1966 and 1969: seven 15-story towers, nineteen 8-story blocks and ten 4-story blocks. These were the "seven towers" referred to in the U2 song "Running to Stand Still". They have since been demolished. Inner Dublin flat complexes, typically of 4-5 storeys include Sheriff Street (demolished), Fatima Mansions (demolished and redeveloped), St Joseph's Gardens (demolished; replaced by Killarney Court flat complex), St Teresa's Gardens, Dolphin House, Liberty House, St Michael's Estate (8 storeys) and O'Devaney Gardens and

3360-640: The Second World War. In the Eastern Bloc , tower blocks were constructed in great numbers to produce plenty of cheap accommodation for the growing postwar populations of the USSR and its satellite states . This took place mostly in the 1950s, 1960s and 1970s, though in the People's Republic of Poland this process started even earlier due to the severe damages that Polish cities sustained during World War II. Throughout

3444-980: The United Nations estimate contributed to 33% of overall worldwide emissions. Including the manufacturing of building materials, the global CO 2 emissions were 39%. If new technologies in construction are not adopted during this time of rapid growth, emissions could double by 2050, according to the United Nations Environment Program . Glass buildings, especially all-glass skyscrapers, contribute significantly to climate change due to their energy inefficiency. While these structures are visually appealing and allow abundant natural light, they also trap heat, necessitating increased use of air conditioning systems, which contribute to higher carbon emissions. Experts advocate for design modifications and potential restrictions on all-glass edifices to mitigate their detrimental environmental impact. Buildings account for

3528-429: The United States, tower blocks are commonly referred to as "midrise" or "highrise apartment buildings", depending on their height, while buildings that house fewer flats (apartments), or are not as tall as the tower blocks, are called "lowrise apartment buildings". Specifically, "midrise" buildings are as tall as the streets are wide, allowing five hours of sunlight on the street. Some of the first residential towers were

3612-468: The apartments lacked appeal and the area quickly became much poorer. From its early days of implementation the concept was criticised for making residents feel unsafe, including large empty common areas dominated by gang culture and crime. The layout was criticised for normalising anti-social behaviour and hampering the efforts of essential services, particularly for law enforcement . The history of microdistricts as an urban planning concept dates back to

As another large example, in 2005 it was decided to carry out a 20-year process of demolition and replacement of dwellings with modern houses in the Aylesbury Estate in south London, built in 1970. The Hulme Crescents in Manchester were the largest social housing scheme in Europe when built in 1972 but lasted just 22 years. The Crescents had one of

3780-442: The building standpipe system, HVAC systems (heating, ventilation and air conditioning), fire sprinkler systems, and other things such as stairwell and elevator evacuations pose significant problems. Studies are often required to ensure that pedestrian wind comfort and wind danger concerns are addressed. In order to allow less wind exposure, to transmit more daylight to the ground and to appear more slender, many high-rises have

3864-569: The buildings and developments are Trellick Tower , Balfron Tower , Broadwater Farm , Robin Hood Gardens and Keeling House in London, Hunslet Grange in Leeds and Park Hill, Sheffield , and Castlefields and Southgate Estate , Runcorn . These were an attempt to develop a new architecture, differentiated from earlier large housing estates, such as Quarry Hill flats in Leeds. Alison and Peter Smithson were

3948-446: The cities, some of which were made up of slums. Construction continued in the 1970s and 1980s, under the systematisation programme of Nicolae Ceaușescu , which consisted largely of the demolition and reconstruction of existing villages, towns, and cities, in whole or in part, in order to build blocks of flats ( blocuri ), as a result of increasing urbanisation following an accelerated industrialisation process. In Czechoslovakia (now

These eleven-story towers were completed in 1961 and were the first tall council housing blocks on the island of Ireland. The NIHT also designed the inner city Divis Flats complex. The six-to-eight-storey deck-access flats that comprised most of

4116-413: The collapse of Ronan Point in 1968. Although Tower blocks are controversial and numerous examples have been demolished, many still remain in large cities. Due to lack of proper regulation, some tower blocks present a significant fire risk and even though there have been efforts to make them more safe, modern safety precautions can be prohibitively expensive to retrofit. The Grenfell Tower fire in 2017

4200-429: The concept, see Nonbuilding structure for contrast. Buildings serve several societal needs – occupancy , primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the outside (a place that may be harsh and harmful at times). Ever since

4284-401: The desert". The engineer's definition of high-rise buildings comes from the development of fire trucks in the late 19th century. Magirus had shown the first cogwheel sliding ladder in 1864. The first turntable ladder drawn by horses was developed in 1892 which had a length of 25 meters. The extension ladder was motorized by Magirus in 1904. The definition of a maximum of 22 meters for

Although not correctly defined as towers, many modern high-rise buildings (in particular skyscraper ) have 'tower' in their name or are colloquially called 'towers'. Skyscrapers are more properly classified as 'buildings'. In the United Kingdom , tall domestic buildings are referred to as tower blocks . In the United States , the original World Trade Center had

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

4620-688: The first millennium BC, is derived from the Phoenician word for watchtower ('migdol'). The Romans utilised octagonal towers as elements of Diocletian's Palace in Croatia , which monument dates to approximately 300 AD, while the Servian Walls (4th century BC) and the Aurelian Walls (3rd century AD) featured square ones. The Chinese used towers as integrated elements of the Great Wall of China in 210 BC during

4704-591: 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

4788-592: 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

4872-550: 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

4956-585: The houses have others on either side. Apartments may be built round courtyards or as rectangular blocks surrounded by plots of ground. Houses built as single dwellings may later be divided into apartments or bedsitters , or converted to other uses (e.g., offices or shops). Hotels , especially of the extended-stay variety ( apartels ), can be classed as residential. Building types may range from huts to multimillion-dollar high-rise apartment blocks able to house thousands of people. Increasing settlement density in buildings (and smaller distances between buildings)

The Royal Hospital built three thirteen-story towers for use as staff accommodation, prominently located adjacent to

5628-765: 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

A third limit is dynamic; a tower is subject to varying winds, vortex shedding, seismic disturbances etc. These are often dealt with through a combination of simple strength and stiffness, as well as in some cases tuned mass dampers to damp out movements. Varying or tapering the outer aspect of the tower with height avoids vibrations due to vortex shedding occurring along

Vehicles—such as trailers , caravans , ships and passenger aircraft —are treated as "buildings" for life safety purposes. Buildings represent a large part of energy, electricity, water and materials consumption. As of 2020, they account for 37% of global energy use and energy-related CO 2 emissions, which

5964-601: The range of the transmitter. The CN Tower in Toronto, Ontario , Canada was built as a communications tower, with the capability to act as both a transmitter and repeater. Towers can also be used to support bridges, and can reach heights that rival some of the tallest buildings above-water. Their use is most prevalent in suspension bridges and cable-stayed bridges . The use of the pylon, a simple tower structure, has also helped to build railroad bridges, mass-transit systems, and harbors.
