Designs released by architect RSHP for final public consultation show the landmark building would rise to 54 storeys. The scheme reflects growing confidence in the City office market and further impetus to start work on the next generation of towers.

Plans will be submitted in the next few months for the scheme, including an expansive arcade at the street level rising to 18 and a 6-storey standalone cultural building for public use next to the main tower.

It would replace a 1976-built 24-floor office block on the site which was damaged after an IRA bomb exploded in the City of London in 1993. The restored building is presently home to contractor Multiplex.

The constraints and challenges with the existing building mean that redevelopment has emerged as the most appropriate option for the site.

Brookfield said it would aspire to retain and re-use elements of the existing building where feasible and will be targeting a retention of 48% of the current building’s mass through the re-use of its existing foundation.
