TOWER 42 is the third tallest skyscraper in the
City of London
The tower, designed by Richard Seifert and engineered by Pell Frischmann , is located at 25 Old Broad Street. It was built by John Mowlem "> The tower's shape has been compared to that of the logo for NatWest, although its architect Richard Seifert always denied the similarity. Simplified plan and dimetric projection showing the shape of the top of Tower 42.
The National Westminster Tower's status as the first skyscraper in
the City was a coup for NatWest, but was extremely controversial at
the time, as it was a major departure from the previous restrictions
on tall buildings in London. The original concept dates back to the
early 1960s, predating the formation of the National Westminster Bank.
The site was then the headquarters of the
National Provincial Bank
Early designs envisaged a tower of 137 m (450 ft); this developed into a design with a 197 m (647 ft) tower as its centrepiece, proposed in 1964 by architect Richard Seifert . The plan attracted opposition, partly because of the unprecedented height of the design and partly because of the proposed demolition of the 19th century bank building at 15 Bishopsgate, which dated from 1865 and was designed by architect John Gibson . Seifert, who had developed a reputation for overcoming planning objections, organised an exhibition in which he presented two alternative visions: his preferred design, and a second design featuring a 500 ft tower with an "absurdly squat" second tower alongside. Visitors were invited to vote and overwhelmingly chose the single tower design. The final design preserved the Gibson banking hall and the tower's height was reduced to 183 m (600 ft).
Demolition of the site commenced in 1970 and the tower was completed in 1980. The building was constructed by John Mowlem 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 the Big Bang , when there was a
lesser requirement for large trading floors, the bank decided not to
locate its foreign exchange and money market trading operation ("World
Money Centre") into the tower. This unit remained in its existing
location at 53 Threadneedle Street. Other international banking units,
such as International Westminster Bank 's
Innovative features in the design included double-decked elevators, which provide an express service between the ground/mezzanine levels and the sky lobbies at levels 23 and 24. Double decked elevators 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.
Following Nat West'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

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.

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.
