The practice is down to the last two in the international contest to mastermind a huge carbon-neutral commercial, residential, shopping and leisure scheme.
Although the winner is not officially unveiled until next month, the AJ understands the British firm may be disappointed, with an as-yet-unnamed German practice currently in pole position to scoop the contest.
Sheppard Robson's seven-tower 'ultra low energy' scheme will feature a six-storey, 750m-long skybridge housing 'an exclusive retail destination topped by a botanical garden.'
The development will also include a five-star hotel and a residential skyscraper, and aims to harvest rainwater and recycle all grey water via a reed-bed filtration system - part of a ground floor eco-park.
The scheme was drawn up in collaboration with Battle McCarthy, Arup Structures and landscape architects Edco.
