Yesterday, the Leeds Partnership revealed that it had asked Farrell to mastermind the £500 million mixed-use redevelopment of the city's Eastgate and Harewood quarters.
The proposals, which go on public display tomorrow, will create 93,000m 2of new retail space, as well as 600 homes, a medical centre and a church.
There are also plans for two department stores on the 8.5ha split site, including a flagship building for retailer John Lewis.
Director of development at Leeds City Council, Jean Dent, said: 'The proposals for Eastgate and Harewood quarters are of major importance, representing a key part of the council's overall strategy to reinforce the quality of retailing in Leeds city centre.'
She added: 'The delivery of this scheme will not only bring forward the redevelopment of this important area of the city, reconnecting Eastgate with the rest of the city centre, but will also play an essential role in complementing the proposals for Trinity quarter.'
The Leeds Partnership - a joint venture between developers Hammerson and Town Centre Securities - hopes to submit an outline planning application for the scheme in the next few months, with a view to starting on site in 2008.
