Around 1,000 new construction jobs could be created by building between 30 and 40 new shops, new flagship stores, and an intergrated transport hub.
Plans will be on show to shoppers until 22 October and a planning application will go to Thurrock Development Corporation later this year.
Lakeside’s general manager, Paul Lancaster, said: “This development will allow us to introduce new brands and widen our offer to customers.
“The proposed integrated transport hub will make using public transport easier, with shorter and sheltered links between bus and rail.
“This £180m project is a major statement of our confidence in Lakeside and we hope it will further raise the profile of Thurrock for other businesses.”
