The works will pave the way for main contractor Multiplex to start work on the 2.5-acre site to create a ‘commercially led’ mixed-use development.

Designed by Make Architects, the major project will involve a 25-storey office tower connected to two buildings of 14 and 6 storeys.

The design also features external terraces and balconies overlooking the Thames, and a new public rooftop restaurant and terrace, as well as transforming 40 per cent of the site into public.

The scheme known as 72 Upper Ground will be all-electric, fossil fuel-free, while targeting net zero carbon in operation along with BREEAM ‘Outstanding’.

A 6-storey podium will support the two office buildings and create a rooftop garden

Multiplex will also construct green spaces to boost biodiversity and reduce CO2 levels.

Callum Tuckett, UK Managing Director at Multiplex, said: “We are very proud to be involved with such an exciting mixed-use development, which will transform this part of the South Bank.

“We have a highly experienced and talented project team on site and are looking forward to delivering a high-quality scheme that matches the ambitions of all project partners and stakeholders.”

Shinichi Kagitomi, chief executive of developer Mitsubishi Estate London, said: “Starting on site marks a major milestone for this landmark development, which will make a significant positive contribution to the South Bank.”

The project is due to complete in 2029.
