40 Leadenhall Street


40 Leadenhall Street is a proposed office-led development in London that has been approved for construction. It is located within the City of London financial district and is one of a number of new building developments for the area.
The development site is currently being cleared. Construction will commence in early 2020 with a three year build period.

Site ownership and location

The development site, known as the Leadenhall Triangle, was purchased by Henderson Global Investors in June 2011 for around £190 million.
It is situated in the Aldgate ward in the eastern portion of the City of London, and is a short distance from the Leadenhall Building and the Lloyd's building.

Planning application

In October 2013 Vanquish Properties Limited Partnership applied for planning permission to construct a building comprising 10, 14 and 34 storeys to a maximum height of 170m on a site bounded by 19-21 and 22 Billiter Street, 49 Leadenhall Street, 108 and 109-114 Fenchurch Street, 6-8 and 9-13 Fenchurch Buildings. The listed building at 19 - 21 Billiter Street is to be retained whilst all other existing properties on the site will be demolished.
Planning permission was granted by the City of London Corporation on 29 May 2014, following a resolution to grant permission by the Planning and Transportation Committee on 25 February 2014, subject to certain planning obligations being met.
Following Brexit, the developer announced that construction will only go ahead when a sufficient amount of office space has been pre-let.
In October 2019 it was announced M&G and Prudential have bought the site and will fund its construction for £875m with a final development value of £1.4bn. Build will start early in 2020 once Keltbray completes clearing the Leadenhall Triangle site. This is despite no pre-let.

Design

The building varies in height by being laid in a series of vertical slices ranging from 7 to 34 stories at the Leadenhall Street end.
