Tower 42 is a 183 metres (600 ft) skyscraper in the City of London. It is the fifth-tallest in the City and fifteenth-tallest in Greater London. Its original name was the National Westminster Tower (commonly known as the NatWest Tower), having been built to house NatWest's international headquarters. Seen from above, the shape of the tower resembles that of the NatWest logo (three chevrons in a hexagonal arrangement).

The tower, designed by Richard Seifert and engineered by Pell Frischmann, is located at 25 Old Broad Street in the ward of Cornhill. It was built by John Mowlem & Co between 1971 and 1980, first occupied in 1980, and formally opened on 11 June 1981 by Queen Elizabeth II.

The construction cost was £72 million (approximately £222 million today). It is 183 metres (600 ft) high, which made it the tallest building in the United Kingdom until the topping out of One Canada Square at Canary Wharf in 1990. It was the tallest building to have been built in London in the 1980s. It held the status of tallest building in the City of London for 30 years, until it was surpassed by the Heron Tower in December 2009.

The building today is multi-tenanted and comprises Grade A office space and restaurant facilities, with restaurants on the 24th and 42nd floors. In 2011, it was bought by the South African businessman Nathan Kirsh for £282.5 million.

History

Construction

Demolition of the site commenced in 1970 and the tower was completed in 1980. The building was constructed by John Mowlem & Co around a huge concrete core from which the floors are cantilevered, giving it great strength but significantly limiting the amount of office space available.

In total, there are 47 levels above ground, of which 42 are cantilevered. The lowest cantilevered floor is designated Level 1, but is in fact the fourth level above ground. The cantilevered floors are designed as three segments, or leaves, which approximately correspond to the three chevrons of the NatWest logo when viewed in plan. The two lowest cantilevered levels (1 and 2) are formed of a single "leaf"; and the next two (3 and 4) are formed of two leaves. This pattern is repeated at the top, so that only levels 5 to 38 extend around the whole of the building.

The limitations of the design were immediately apparent - even though the building opened six years before Big Bang, and so there was less of a requirement for large trading floors, the bank decided not to locate its foreign exchange and money market trading operation ("World Money Centre") in the tower; the unit remained in its existing location at 53 Threadneedle Street. Other international banking units, such as International Westminster Bank's London Branch and the Nostro Reconciliations Department remained at their locations (at 41 Threadneedle Street and Park House, Finsbury Square, respectively) due to lack of space in the tower.

Innovative features in the design included double-decked lifts, which provide an express service between the ground/mezzanine levels and the sky lobbies at levels 23 and 24. Double-decked lifts and sky lobbies were both new to the UK at the time. Other innovative features included an internal automated "mail train" used for mail deliveries and document distribution; an automated external window washing system; and computer controlled air conditioning. The tower also had its own telephone exchange in one of the basement levels – this area was decorated with panoramic photographs of the London skyline, creating the illusion of being above ground.

Fire suppression design features included pressurised stairwells, smoke venting and fire retardant floor barriers. However, at the time of design, fire sprinkler systems were not mandatory in the UK and so were not installed. It was this omission, coupled with a fire in the tower during the 1996 refurbishment, that prompted the Greater London Council to amend its fire regulations and require sprinkler installations at all buildings.

The cantilever is constructed to take advantage of the air rights granted to it and the neighbouring site whilst respecting the banking hall on that adjacent site, as only one building was allowed to be developed. For a time it was the tallest cantilever in the world.

Ownership

Following NatWest's refurbishment of the tower, the bank renamed it the International Finance Centre, in 1997. The building was subsequently acquired by Hermes Real Estate and BlackRock's UK property fund in 1998 for GB£226 million. In 2010 they put the property on the market at an expected price of GB£300 million. This would potentially have been the largest single commercial property sale in the City of London in 2010. In July 2010 it was reported that Chinese Estates Group had entered exclusive discussions to buy Tower 42. but this deal did not conclude and it was sold in 2011 to South African businessman Nathan Kirsh for £282.5 million.

Upon completion, the tower was occupied by a large part of NatWest's International Division. The upper floors were occupied by the division's executive management, marketing, and regional offices, moving from various locations in the City of London. The lower floors were occupied by NatWest's Overseas Branch, moving from its previous location at 52/53 Threadneedle Street.

The full floor configuration was as follows:

The adjacent annexe building at 27 Old Broad Street was occupied by NatWest's Overseas Branch cashiers and foreign notes and coin dealing operation.

1993 bombing and refurbishment

In 1993, NatWest had planned a major premises relocation that would have seen the International Banking Division move from the tower and be replaced with its Domestic Banking Division, enabling the bank to terminate its lease of the Drapers Gardens tower. These plans had to be abandoned after the tower was damaged in the April 1993 Bishopsgate bombing, a Provisional Irish Republican Army truck bombing in the Bishopsgate area of the City of London. The bomb killed one person and extensively damaged the tower and many other buildings in the vicinity, causing a total of over £1 billion worth of damage to the area. The tower suffered severe damage and had to be entirely reclad and internally refurbished at a cost of £75 million. (Demolition was considered, but would have been too difficult and expensive.) The external re-clad was carried out by Alternative Access Logistics with the use of a multi-deck space frame system to access three floors at once with the ability to move up and down the whole building.

On 17 January 1996, during the repairs and possibly from the welding being undertaken, a fire started at the top of the building. Five hundred workmen were evacuated and smoke was seen coming out of the top of the building. A helicopter using thermal imaging equipment pinpointed the source of the fire, which was on the 45th floor in a glass-fibre cooling tower. After refurbishment, NatWest decided not to re-occupy and renamed the building the International Financial Centre, then sold it.

Current occupation

Previous owners, UK property company Greycoat, renamed it Tower 42 in 1995, in reference to its 42 cantilevered floors. It is now a general-purpose office building occupied by a variety of companies.

Current tenants of the building include:

Lighting display

In June 2012, a Capix LED multi-media lighting system was installed around levels 39 to 45. This replaced the previous high-energy floodlighting at the top of the building.

The lighting system is formed of thousands of pixels mounted on a chain netting that is affixed to the surface of the building. Each pixel is formed of three RGB LED units, allowing a variety of lighting designs and colours to be displayed. The system was designed by SVM Associates and Zumtobel.

The display featured the Olympic Rings during the London 2012 Olympic Games and the Paralympic Agitos during the London 2012 Paralympic Games.

Ranking among London high-rise buildings

The National Westminster Tower was the tallest building in London and the United Kingdom for 10 years. At its completion in 1980, it claimed this title from the 177-metre (581 ft) 189-metre (620 ft) with antenna Post Office Tower, a transmission tower located at 60 Cleveland Street in Fitzrovia, London.

Tower 42 is now the third-tallest tower in the City of London, having been overtaken in 2010 by the 230-metre (750 ft) Heron Tower and the 225-metre (738 ft) Leadenhall Building in 2014. It is the eighth-tallest in London overall.

Previous buildings on the site

• Gresham House, built in 1563 by Sir Thomas Gresham. Gresham was a businessman who helped set up the Royal Exchange. Upon the death of his wife in 1596, Gresham House became the 'Institute for Physic, Civil Law, Music, Astronomy, Geometry and Rhetoric', as directed by Gresham's will (Sir Thomas died 17 years earlier). Professors at Gresham College, described as the Third University of England by Chief Justice Coke in 1612, included Robert Hooke, Sir Christopher Wren and the composer John Bull. The building survived the Great Fire, and saw use as a garrison, a Guildhall and Royal exchange. The College moved to Gresham Street. Gresham House was demolished in 1768 and a new Gresham House was built in its place.
• Crosby Hall, built in 1466 and named for its builder, the London merchant and alderman, Sir John Crosby. Its most famous occupant was King Richard III. A famous visitor was William Shakespeare. A scene of his play, Richard III, in which the future Richard III, then Duke of Gloucester, plots his route to the crown, is set in Crosby Hall.
• Crosby Place, which was built in 1596, the year that Richard III was written.
• Palmerston House was a building that survived from the 19th century, through both world wars. It was named after the Third Viscount Palmerston. It stood at 51-55 Broad Street. It was occupied for some time by the Cunard Steam Shipping Company.
