Bennetts Associates has won planning consent for the redevelopment of New Street Square in London's EC2 area.
The design - for Land Securities - incorporates 61,850m 2of offices and 2,285m 2of retail space and replaces a previous approval for a single 58,400m 2headquarters office building submitted by RHWL.
The development, which centres around a landscaped City square, will include four main buildings and a pavilion and will replace the existing structures built during the 1960s.
The pivotal block will be building A at the northern end of the site, its maximum 19 storeys stepping down to 15 at New Fetter Lane.
Building B at the north-east will rise to 11 storeys and restore the post-war street frontage that existed prior to the current development.
Closing the east side, building C will be five storeys high and provide a link to the neighbouring conservation area, while building D - which occupies the south-west corner - follows the street edge and steps from 12 storeys down to nine.
The site will form an effective boundary between the City and the West End and will be renamed New Street Square.
