Formerly known as the National Westminster Tower (NatWest Tower for short), Tower 42 – sometimes referred to as London’s first “genuine” skyscraper – was once the tallest building in the London (but now comes in at number eight).
Designed by Richard Seifert & Partners (who had proposed a couple of different options), the 47 storey building at 25 Old Broad Street was built between 1971 and 1980 as the headquarters of the National Westminster Bank.
The length of the build – which ended up costing £72 million – was due to the fact that it was paused in the mid-1970s to allow for a redesign of the ground area after the City of London Club was heritage listed (and thus its planned demolition couldn’t proceed).
Some 42 of its stories are cantilevered off a concrete core which contains elevators and service rooms. It has been repeatedly said the building was designed so that in plan view it resembles the NatWest logo – three interlocking chevrons – but Seifert apparently said this was just a coincidence.
It was formally opened by Queen Elizabeth II on 11th June, 1981, and, at 183 metres tall, was not only the tallest in London but in the entire UK until it was surpassed by One Canada Square in the Docklands in 1990. It remained the tallest building in the City of London until 2009 when Heron Tower took over that title.
Among its innovations were use of sky lobbies – located on levels 23 and 24, they are accessible by express elevators from the ground floor, and an automated external window washing system. Problematically, however, its interior layout proved somewhat inflexible which meant some of the bank’s operations remained outside of the building. Thanks to a need for large trading floors after deregulation in 1986, NatWest subsequently relocated its headquarters.
After the building was badly damaged by an IRA bomb in 1993, the entire tower, under the supervision of GMW Architects, was reclad and the interior refurbished. It was subsequently renamed the International Finance Centre and again renamed in 1998, this time as Tower 42 (a reference to the 42 cantilevered floors).
In 2011, it was purchased by South African businessman Nathan Kirsh for a reported £282.5 million. These days it contains office space, several restaurants, health clubs and other services as well as and a champagne bar with panoramic views, Vertigo 42.
An LED light display was installed in 2012 in time to display the Olympic rings for that year’s Games.
The building was refused listed status in 2014 owing to its now greatly altered nature.
Interestingly, part of the site was once occupied by Crosby Hall, built in 1466 for City alderman Sir John Crosby and one time residence of King Richard III. The hall was relocated to Chelsea in 1910.
