The new building, designed by architects AHMM, aims to deliver around 1.2m sq ft of offices, retail and a transformed public realm next to the train station.
The new plan is larger than the pre-existing planning consent for 945,000 sq ft inherited when the developer bought the site in May 2017.
Fresh plans include a one-acre garden promenade, directly connected to the Waterloo Station concourse which will benefit the 100m users of the station each year.
A public route below the garden called the Waterloo Curve will provide a major new pedestrian street for the area which would be lined with shops and cafés.
The scheme will also facilitate new links into Waterloo Station and help to accommodate the 30% projected passenger growth that is predicted over the next five years.
The client team includes structural engineer Robert Bird Group, with mechanical engineering delivered by Sweco.
The site has four major tube lines running beneath, requiring an innovative engineering solution for the building.
It will be supported on an A-frame structure that spans like a bridge across the site and transfers load into the ground on either side of the tunnels. The base of the building is a heavy ground- bearing structure that balances against the heave effect of the tunnels below.
If planning permission is granted, the development will support 11,000 jobs for an area, which has previously seen job numbers decline, supported by a variety of workspaces within the building and an employment, training and skills package for local people.
