Key Details

40 Leadenhall Street, London EC3M 2RY
Autumn 2023
905,000 sq ft>


Stanza at 40 Leadenhall Street is an office development in the City of London EC3.

The site, in the heart of London’s financial district, has permission for the development of two towers, providing 14 and 34 storeys of prime office space. The new buildings’ carbon emissions will be 30% below current regulations and are expected to achieve a BREEAM Excellent rating.

The building is located in the City of London's established and dynamic insurance district of EC3 and within the Eastern Cluster of tall buildings. The site is very well served with public transport surrounded by various bus routes, underground and overground stations. A grade II listed building at 19-21 Billiter Street, built in 1865, will be restored and integrated in the proposed scheme. It is estimated that 390 FTE construction jobs will be created on the site and approximately 7,000 people are expected to work in the building when complete.

Designed by world-class architectural practice, Make, it is formed of vertical slices arranged around the listed building which create a striking and considered vertical composition to complement the more curved and leaning buildings on the London skyline.

The tallest part of the building is positioned at the northern end of the site to take account of neighbouring tall buildings and steps down in height toward the River Thames and Tower of London to the south. The proposed new building is also terraced at a high level on the northern side of Leadenhall Street so that it remains out of sight when travelling east along Fleet Street along the ceremonial route to St Paul's Cathedral. Ground floor entrance and retail frontages are set back to create generous pedestrian zones, wider pavements and spaces along key pedestrian routes on adjacent Leadenhall Street, Fenchurch Street, Billiter Street and Fenchurch Buildings.

Henderson acquired the 'Leadenhall Triangle' site on behalf of clients in May 2011.

The development has been designed to meet the BREEAM NC 2011 Excellent standard and the sustainability measures proposed will allow the Building Emissions Rate to be reduced by a minimum of 40% below Part L2A of the 2010 Building Regulations. The building has 1,067 bicycle spaces with additional mobility scooter charging spaces, 113 showers and two disabled car parking spaces.


Construction started in March 2020, with completion expected by September 2023.

2020 M&G Real Estate appoints Savills, Knight Frank and Cushman & Wakefield as joint agents on 40 Leadenhall Street.

2019 November - Acquired for £875 million from Nuveen, the site was purchased through M&G’s £144 billion Prudential with-profits fund, on behalf of the fund’s five million UK policyholders. The deal provides clients and customers with good value exposure to the central London office market, which offers strong value in comparison to other global cities such as Frankfurt, Paris and Tokyo.

2019 February - RLF has been appointed as the Principal Designer and CDM Advisor.
