A planning application was submitted to the Corporation of London on the 10th February 2004. |
| - |
The redevelopment involved the demolition of 122 Leadenhall Street, a 14-storey office tower built in 1969. |
| - |
The building's height above ordnance
datum (AOD) is 239.4 metres (785 feet). |
| - |
The vertical circulation is located on the north side, opposite the lobby and main entrance facing The Lloyd's Building. |
| - |
The floor plates vary in size which allows for great flexibility in providing office space which can be cellular or open-plan. |
| - |
The open space at the base rises to seven storeys and contains trees and retail amenities. |
| - |
Each floor plate on the south side is stepped back by .75 metres from the one below, resulting in the distinctive wedge shape when viewed from the east and west. |
| - |
The distinctive wedge shape is designed to virtually eliminate the building intruding into the sight-line of St. Paul's Cathedral when viewed along Fleet Street and up Ludgate Hill. |
| - |
Of the 29 lifts, 22 are exterior, glass, and fully scenic. |
| - |
The ladder frame on the rear (north side) encloses the fire-fighting cores which serve the office floors. |
| - |
The support core to the north is conceived as a separate tower which contains the passenger and freight lifts, service risers, floor plant and lavatories. |
| - |
The low-, mid- and high-rise sections are served by three groups of passenger lifts which are connected by two transfer lobbies at floors ten and twenty-four respectively. |
| - |
Because of the northern support core's relative position to the office floors, the structure doesn't require over-cladding with fire protection, meaning it can be designed and expressed as visible steelwork. |
| - |
Solar gain to the office areas is countered with the incorporation of remotely controlled blinds. |
