General information Status Under construction Location London, United Kingdom Completed 2014 (estimate) Height Roof 225 metres (738 ft) Technical details Floor count 48 Floor area 84,424 m2 (908,730 sq ft) Design and construction Architect Rogers Stirk Harbour + Partners Structural engineer Arup 122 Leadenhall Street is an address on Leadenhall Street in London where the 225 m (737 ft) tall Leadenhall Building is currently under construction. The skyscraper, due for completion in mid-2014, is designed by Richard Rogers and informally known as the Cheesegrater because of its distinctive wedge shape. It is one of a number of new tall buildings for the City of London financial district, with others including 20 Fenchurch Street (known as the Walkie-Talkie), the Pinnacle, and an as yet unnamed project at 52-54 Lime Street. The site is adjacent to the Lloyd's building, also designed by Rogers, which is the current home of the insurance market Lloyd's of London. Until 2007 the Leadenhall site was occupied by a building owned by the developer British Land and designed by Gollins Melvin Ward Partnership that was constructed in the 1960s. That building was demolished in preparation for redevelopment of the site. By December 2009, the site was cleared but construction had stalled. The project, initially delayed due to the financial crisis, was revived in October 2010 and Oxford Properties is now co-developing the property in partnership with British Land. In May 2013, the co-developers announced that the building is over 51% pre-let, with tenancy agreements reached with insurance broker Aon and insurance company Amlin.
