Stock Exchange Tower

Standing at 100 metres (328 ft) tall with 26 floors, the Stock Exchange Tower was completed by Trollope & Colls[1] in 1970 and officially opened by Queen Elizabeth II on 8 November 1972.

[3] On 20 July 1990, the Provisional IRA exploded a bomb inside the tower, causing its evacuation.

It was also evacuated on 11 September 2001, after the terrorist attacks on the World Trade Center in New York City.

[4] The building underwent a major renovation which saw its pre-cast concrete façade reclad in a glass curtain wall, and thousands of square metres of additional office space created, including a new 10-storey building at No.

As part of the renovation, the floor plates were extended beyond the perimeter of the original building to give more overall space.
