Tower block: the story on HearLore | HearLore
Tower block
In the 16th century, the Yemeni city of Shibam rose from the desert sands as a vertical fortress, a cluster of five hundred mud-brick towers reaching up to sixteen stories high to protect residents from Bedouin raids. These structures, known as the tallest mud buildings in the world, stand as a testament to early urban planning based on the principle of vertical construction, earning the city the nickname Manhattan of the desert. While ancient Rome had already experimented with multi-story insulae, some reaching ten stories and one reportedly boasting two hundred stairs, the Roman emperors struggled to enforce height limits due to frequent collapses. The lower floors of these ancient towers housed shops or wealthy families, while the upper stories were rented to the lower classes, creating a social stratification that mirrored the physical elevation of the buildings. In Arab Egypt, the capital city of Fustat featured high-rise residential buildings that could accommodate hundreds of people, with some rising as high as fourteen stories and featuring roof gardens irrigated by ox-drawn water wheels.
The Fire Engine Definition
The modern engineering definition of a high-rise building emerged not from architectural ambition but from the limitations of firefighting equipment in the late 19th century. Magirus introduced the first cogwheel sliding ladder in 1864, followed by the first turntable ladder drawn by horses in 1892, which reached a length of 25 meters. By 1904, the extension ladder was motorized, yet the maximum height for the highest floor remained common at 22 meters, a standard that persists in German building regulations today. Any building exceeding the height of the usual turntable ladders in a city must install additional fire safety equipment, creating a distinct regulatory section for these structures. This practical constraint shaped the global understanding of what constitutes a high-rise, distinguishing it from low-rise buildings and influencing the design of structural systems like reinforced concrete and steel frames. The development of fire trucks and ladders forced engineers to confront the unique challenges of evacuating occupants from great heights, leading to the creation of building standpipe systems and complex HVAC systems that remain critical to modern safety.
Streets in the Sky
In the 1960s and 1970s, British architects attempted to recreate the social fabric of a city street within the walls of high-rise blocks, a concept known as Streets in the Sky. Examples like Trellick Tower, Balfron Tower, and Park Hill in Sheffield included shops and community facilities within the towers, aiming to replace run-down terraced housing with modern improvements. However, the ideal rarely worked in practice; these walkways were not thoroughfares and often came to dead ends multiple storeys above the ground. Lacking a regular flow of passers-by, the stairwells and walkways became invisible to the outside world, creating an environment where crime and disorder could flourish without the eyes on the street advocated by Jane Jacobs. The Unité d'Habitation in Marseille provided a more successful example with its fifth-floor walkway including a shop and café, but most other projects, such as the Hulme Crescents in Manchester, lasted only 22 years before being marred by design and practical problems. The failure of these concepts led to the demolition of many such estates, including the Aylesbury Estate in south London, which underwent a 20-year process of replacement with modern houses.

Why did the Streets in the Sky concept fail in the 1960s and 1970s?
The Streets in the Sky concept failed because the walkways were not thoroughfares and often came to dead ends multiple storeys above the ground.

What happened to the Eastern Bloc tower blocks known as Khrushchyovka?
Tower blocks known as Khrushchyovka were constructed in great numbers in the USSR and its satellite states mostly during the 1950s, 1960s, and 1970s to produce cheap accommodation. Since the dissolution of the Soviet Union, many former Eastern Bloc countries have begun construction of new, more expensive and modern housing, while others have begun to renovate the previously grey exteriors with new coats of paint or thorough modernization.
When did the collapse of Ronan Point occur and what was its impact?
The collapse of Ronan Point occurred in 1968 and marked a turning point that led to a period of controversy and demolition for many examples of Tower blocks. The Grenfell Tower fire in 2017 further made Tower blocks less desirable to British residents, partly caused by council ignorance despite complaints from a local action group about fire hazards years before the incident.
What is the tallest residential building in the world and when was it built?
Currently, the tallest residential building in the world is Central Park Tower located in Midtown Manhattan, having a height of 1,550 feet with the highest occupied floor at 1,434 feet. This structure, situated on Billionaires' Row, represents the pinnacle of modern residential high-rise design and towers over the city skyline.
The post-World War II era saw the rise of towers in the park and microdistricts, a morphology of modernist high-rise apartment buildings characterized by a high-rise building surrounded by a swath of landscaped land. This ideology, popularized by Le Corbusier with the Plan Voisin, aimed to reduce urban congestion and was introduced in North America, Europe, and Australia as a solution for public housing. By the early 1970s, opposition to this style mounted, with many urban planners referring to these neighborhoods as ghettos. Neighbourhoods like St. James Town were originally designed to house young swinging single middle-class residents, but the apartments lacked appeal and the area quickly became much poorer. The layout normalized anti-social behaviour and hampered the efforts of essential services, particularly law enforcement, as large empty common areas were dominated by gang culture and crime. In the United States, government experiments in the 1960s and 1970s to use high-rise apartments as a means of providing housing for the poor broadly resulted in failure, with projects like Cabrini, Green, Robert Taylor Homes, and Pruitt, Igoe falling victim to ghettofication and eventually being torn down.
The Concrete Legacy of the East
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, mostly during the 1950s, 1960s, and 1970s. These blocky buildings, colloquially known as Khrushchyovka, were built in the specific socialist realist style of architecture that was dominant in the territories east of the Iron Curtain. In Romania, the mass construction of standardized housing blocks began in the 1950s and 1960s, continuing under the systematization programme of Nicolae Ceaușescu, which involved the demolition and reconstruction of existing villages and towns. In Czechoslovakia, panelák building under Marxism, Leninism resulted from the postwar housing shortage and the ideology of the ruling party. 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. Since the dissolution of the Soviet Union, many former Eastern Bloc countries have begun construction of new, more expensive and modern housing, while others have begun to renovate the previously grey exteriors with new coats of paint or thorough modernization.
The British Collapse
Tower blocks were first built in the United Kingdom after the Second World War as a cheap way to replace 19th-century urban slums and war-damaged buildings, but they quickly fell out of favour as they attracted rising crime and social disorder. The collapse of Ronan Point in 1968 marked a turning point, leading to a period of controversy and demolition for many examples. The Grenfell Tower fire in 2017 further made tower blocks less desirable to British residents, partly caused by council ignorance despite complaints from a local action group about fire hazards years before the incident. In the Republic of Ireland, the majority of residential high-rise buildings were concentrated in the suburb of Ballymun, Dublin, known as the seven towers referenced in the U2 song Running to Stand Still, which have since been demolished. In Northern Ireland, the mid-rise Divis flats complex in west Belfast was built between 1968 and 1972 and demolished in the early 1990s after residents demanded new houses due to mounting problems. The Northern Ireland Housing Trust designed the inner city Divis Flats complex, which were of poor build quality and all demolished by the early 1990s, while similar slab blocks were built in East Belfast and Derry's Bogside area, all of which have been demolished.
The Vertical Communities of Asia
Residential tower complexes are common in Asian countries such as China, India, Bangladesh, Indonesia, Taiwan, Singapore, Japan, Pakistan, Iran, and South Korea, where 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, with over 60% of Hong Kong residents living in apartments, many of them condominiums. Innovative architecture firms such as WOHA in Singapore, Mass Studies in Seoul, and Amateur Architecture Studio in Hangzhou have transformed residential towers into vertical communities or vertical cities in the sky. The Vertical Courtyard Apartments in Hangzhou, designed by Wang Shu, feature six 26-story towers where every third story opens into a private courtyard, creating the illusion of living on the second floor. In South Korea, approximately 80% of Seoul's residents live in apartment complexes which comprise 98% of recent residential construction, with the Samsung Tower Palace in Seoul standing as the tallest apartment complex in Asia. The South Korean government needed to build many apartment complexes in the cities to accommodate citizens, and in the 60 years since, tower blocks have become more common, integrating shopping malls, parking systems, and other convenient facilities.
The Tallest Residential Tower
Currently, the tallest residential building in the world is Central Park Tower located in Midtown Manhattan, having a height of 1,550 feet with the highest occupied floor at 1,434 feet. This structure, situated on Billionaires' Row, represents the pinnacle of modern residential high-rise design, towering over the city skyline. In contrast to the public housing failures of the mid-20th century, commercially developed high-rise apartment buildings continue to flourish in cities around the United States, largely due to high land prices and the housing boom of the 2000s. The Upper East Side in New York City, featuring high-rise apartments, is the wealthiest urban neighborhood in the United States. The history of high-rise living has evolved from ancient mud-brick fortresses to modern steel and concrete giants, with the Central Park Tower standing as a symbol of contemporary urban density and luxury. The building's design incorporates advanced structural systems to withstand seismic activity and wind forces, ensuring the safety and comfort of its residents while maintaining the aesthetic appeal that defines modern skyscraper architecture.
