A public consultation will launch next week for the £3 billion Arden Cross project in Solihull.
The scheme has been created to maximise the benefits of the new HS2 Interchange station east of Birmingham Airport which received planning consent this week.
The long-term aim for Arden Cross is to create a new commercial and residential hub which could comprise up to 3,000 new homes and six million sq ft of commercial space which will support 27,000 jobs.
The site covers more than 340 acres next to the M42 and regional chiefs claim it could add £1 billion a year to the local economy.
There will also be people mover connecting Interchange with the airport, NEC campus and Birmingham International station.
Interchange is one of four new stations planned for the first phase of HS2 between London and Birmingham and will sit at the heart of Arden Cross.
The site will neighbour other facilities of immense economic significance to the West Midlands including Resorts World, Birmingham Business Park and Jaguar Land Rover - a cluster area collectively known as 'The Hub'.
Project director Ben Gray said: "The intention for Arden Cross is to deliver a world-class development with the HS2 Interchange station at its heart.
"By bringing our masterplan details out to public consultation, we are a step closer to delivering that ambition.
"The 346-acre site provides the opportunity to deliver significant economic growth and a sustainable mixed-use environment, bringing together new homes, work and learning places, all served by extensive transport links and car-free public spaces.
"Unlocking this transformational opportunity will require a truly collaborative approach between the public and private sector."
The consultation runs from September 1 to 30 and any feedback or comments can be posted at ardencross.com/consultation. People can also register their interest to receive information by connecting via social media channels or emailing info@ardencross.com.
