Eastside is being promoted as the Whitehall of the Midlands, with Birmingham fighting to lure thousands of civil service jobs from London.
City council officials are actively marketing major development suites in Digbeth as ideal locations to relocate government offices from the capital.
The strategy initially focuses on attracting up to 8,000 Ministry of Justice jobs, in what would be the biggest exodus of staff so far from the South-east.
But Birmingham’s departing director for regeneration, Clive Dutton, has spoken about a “far bigger picture”, in which Birmingham sells itself as an ideal location and first-choice city for the type of high-quality modern offices and lifestyle offer required by the civil service.
Sites to the west of the city centre are also being suggested as possible locations for office development as Birmingham seeks to stay ahead of rival UK cities Manchester, Leeds and Liverpool who are also battling to take advantage of the government’s intention to move administrators from London to the regions.
The jobs shift was given greater emphasis in Chancellor Alistair Darling’s last Budget, both as a cost-saving measure to ditch expensive central London office accommodation and as a method of rejuvinating regional cities.
Mr Dutton was speaking after the council planning committee approved the design of a 975-space seven-storey car park at Eastside, at a cost of £12 million.
That decision will allow land at Millennium Point, currently used for parking, to be cleared and development of a £12 million city park to take place.
The eight-acre park, a green lung on the edge of the city centre, would be an “unbelievably important” selling point for Eastside, Mr Dutton insisted.
Planning permission exists for four huge mixed-use projects at Eastside – Masshouse, City Park Gate, Eastside Locks and Curzon Park.
However, developers are desperately seeking users to occupy the offices element of the schemes.
Mr Dutton, who leaves Birmingham next month to take up a new job masterminding regeneration projects flowing from the 2012 London Olympic Games, said the recession and lack of private sector cash made it even more important to concentrate on attracting public sector jobs.
He added: “It is a no-brainer in the current difficult financial circumstances that you look at government borrowing.
“We have got to present Birmingham in the best possible way to create jobs in a city where we are rapidly approaching 50,000 people out of work.
“We are not taking anything for granted, but it seems to us that Eastside clearly meets the criteria and specification laid down by the government.”
He promised the council would rely on a “sophisticated” approach, selling Birmingham holistically as a place for professionals to live and work.
He added: “The skill is not to do as Manchester have done, which is to say we have a specific sight and that is where you are going to go.
“The more choice you can give in terms of an excellent product will strengthen Birmingham’s position in an unbelievably competitive environment.”
