A resolution to grant planning permission has been awarded for Make’s striking office building in the heart of the City of London’s insurance district. The 40 Leadenhall Street site – also known as the Leadenhall Triangle – is owned by Henderson Global Investors and sits within the City’s dense cluster of tall buildings, defining its easternmost edge.

The scheme varies in height, reaching 154m at its highest point, and creates a striking and harmonious composition of shifting rectilinear planes inspired by the early 20th century skyscrapers of Chicago and New York. Formed from a series of stepped vertical ‘slices’, the building terraces down to reduce its profile in response to key vantage points on the skyline, mediating between the scale of the adjacent towers to the north and west, and the lower buildings to the east and south. The tallest and widest ‘slice’ is positioned closest to the centre of the City cluster and steps down towards the River Thames and the Tower of London.

All buildings on the site will be demolished, with the exception of the highly ornamental Grade II listed 19-21 Billiter Street, dating from 1865, which will be substantially retained, enhanced and sensitively integrated into the scheme. Over 10,000 people will be accommodated in the building on completion, which offers a wide variety of floorplates catering for different office occupier requirements in terms of floor size and divisibility. Over 14% of the site outside of the building footprint will become publicly accessible space; the ground floor double-height entrance lobby and retail entrances are set back to create generous pedestrian zones and active street frontages to most of the perimeter.
