Tower block

A tower block, high-rise, apartment tower, residential tower, apartment block, block of flats, or office tower is a tall building or structure used as a residential and/or office building. In some areas it may be referred to as an "MDU", standing for "Multi Dwelling Unit". In the United States, such a structure is referred to as an apartment building or office building, while a group of such buildings is called an apartment complex or office complex.

High-rise buildings became possible with the invention of the elevator (lift) and cheaper, 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 is no clear difference between a tower block and a skyscraper, although a building with fifty or more stories 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 like the building standpipe system, HVAC systems (heating, ventilation and air conditioning), fire sprinkler system and other things like 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 a design with setbacks.

Tower Block (film)

Tower Block is a British thriller film directed by James Nunn and Ronnie Thompson and written by James Moran. The film stars Sheridan Smith, Jack O'Connell, Ralph Brown, and Russell Tovey and entails residents of a block of flats targeted by an unseen sniper after witnessing the murder of a teenager.

Plot

Since the Second World War, blocks of flats emerged as places for affordable living, but fell into a breeding ground for crime and violence, leaving re-developers to demolish most of them except Tower Block 31, where only the top floor residents refuse to leave. One night in London, England, the tenants witness the murder of 15-year-old boy, Jimmy (Ralph Laurila). Only one person, Becky (Sheridan Smith), tries to help the boy from his masked attackers, but she is left unconscious. Detective DC Devlin (Steven Cree) and his partners attempt to identity the culprits, but they receive zero leads from all tenants who fear to get involved.
