Historical Context

The site is located adjacent to Leadenhall Market in the City of London. The Market was the location of the Forum and Basilica in Roman London where the historic route north from London Bridge (which is now traced by Gracechurch Street and Bishopsgate) meets the important east-west route of Leadenhall Street and Cornhill.
In Tudor and Stuart times the Market became one of the most important places in London, and attracted visitors from abroad to wonder at its industry and prosperity.
In the 19th century the Market was redeveloped by the architect Sir Horace Jones, who transformed its brick and stone buildings into the iron and glass structure we know today, 2016 was the 135th anniversary of opening of Sir Horace Jones’ market.
The current character of Leadenhall Market remains as a trading community, providing one of the main concentrations of retail, food and beverage activity in the City.

The City of London’s Eastern Cluster

1 Leadenhall lies in the ‘Eastern Cluster,’ an area already identified by the City of London Corporation to be suitable for tall buildings.
The Eastern Cluster has an emerging profile that is defined by a ring of tall buildings that surrounds a central group of taller buildings.
Office and employment growth in the area are to be accommodated in this cluster of attractive, sustainably designed tall buildings. The Eastern Cluster is an iconic image of London that will help to attract significant global investment.
The massing at the top of the proposed building diminishes in scale to a height which relates to those of the surrounding buildings, in particular to the proposal at 6-8 Bishopsgate at 185m height Above Ordnance Datum (AOD).
