It is a thirty-one storey structure 111 metres (364 ft) high and was completed in 1972. It was designed by the renowned architect Sir Richard Seifert and built by John Laing Construction Limited. There are plans for a complete recladding of the building's exterior in the near future. Several floors will also be added, increasing its height to around 127 metres (417 ft). New shops and offices will also be built around its base.
The tower was the headquarters of IPC Media (until Easter 2007 - when they moved locally to the Blue Fin building), one of the biggest publishing companies in Europe.
