The proposals, announced yesterday by developers Hammerson and Standard Life Investments, would see the shopping centre add an extra 1.4 million square feet of retail and lesiure space.
According to the developers, the plans would include a cinema complex and hotel accommodation, a "town square", an enlarged and relocated bus station, a new riverside park, and new homes.
A new "living bridge and a green landscaped boulevard" would also span the North Circular road.
The developers said that the new homes are proposed for a plot adjacent to Layland Road and Sturgess Park and would "provide a mixture of one, two and three bedroom apartments but the precise number and the ratio between private and social housing has yet to be determined".
The scheme is part of a larger regeneration plan for Brent Cross and Cricklewood which secured outline planning consent in 2014.
Standard Life Investments and Hammerson intend to submit a detailed planning application for the Brent Cross expansion in spring 2017.
