Wirral Council has said it is looking for investors to develop areas around the Woodside ferry terminal, the town centre and Hamilton Square.
It revealed the plan at MIPIM, Europe's largest property expo in Cannes.
An earlier scheme was abandoned in October as the authority sought "more ambitious" plans.
Council leader Phil Davies said there was "global interest" in the proposals.
"I can only report that I've never had so much interest in the last year or so from people who want to invest in Wirral, particularly in Birkenhead," he said.
"We've had an incredible amount of interest."
The proposal includes money for outlying areas, with plans to redevelop the Woodside waterfront and build residential accommodation with views over Liverpool also announced.

The Daily Telegraph recorded Paul Jerram and Omar Ali as part of an investigation into the allegations.
Mr Jerram, head of medicines management at the Isle of Wight Clinical Commissioning Group (CCG) has been suspended.
Surrey and Sussex Hospital Trust said Mr Ali has resigned.
Both men had been accused of accepting payment to set up meetings between pharmaceutical companies and "advisory boards" responsible for deciding which drugs are used by GPs and hospitals.
A CCG spokesman said: "We recognise that these are serious allegations. We are undertaking an internal investigation and will complete a thorough review."
"Whilst this investigation is being undertaken we have suspended the head of medicines management.
"This is a neutral act which protects both the individual and the organisation.
"In view of the investigation it would be inappropriate to comment further at this time."
Michael Wilson, chief executive of Surrey and Sussex Healthcare NHS Trust, said Mr Ali resigned on Thursday.
"Mr Ali has worked part-time for the Trust for ten years and has correctly declared his independent business with us," he said.
"We do not have knowledge of work that he undertakes in his own personal time."
A Department of Health (DoH) spokesperson said the allegations, if true, amount to an "abuse of trust" placed in the NHS by patients.
The NHS's fraud protection body has launched an "urgent investigation" into the claims, they said.
Mr Ali said as well as working part-time for the NHS he also runs a "market access consulting firm" which runs advisory boards for NHS experts and commercial organisations.
He said he had "done everything by the book" and "always made all the appropriate operational declarations for my consulting work in accordance with the usual NHS governance processes".
"I never allowed my NHS work to be influenced by my other activities," he added.
"A proper examination of the wider debate on this area of the NHS would be of enormous benefit, and could help inform best practice for the future."
