Both schemes feature unusual, intertwined towers and were being billed as unique, future icons by the property developers behind the multimillion developments.
However Aedas's Hong Kong office has questioned the authenticity of Hadid's Dancing Tower designs ( pictured above) claiming it was the first to publicise its proposals for a 330m twin-tower scheme, the Legs project, on Al Reem Island in Abu Dhabi ( pictured below).
Andrew Bromberg, the project architect masterminding the Legs scheme, said he had conceived his towers back in October and went on to say that these designs had been made public in March when they were shown at the international property event MIPIM earlier this year.
And Hadid is adamant she had never seen the Aedas development and had dreamed up her competition-winning 560,000m 2scheme (AJ 22.06.06) long before images of the Legs skyscrapers were ever published.
A spokesman for Hadid said: 'Zaha Hadid Architects was unaware any scheme in Abu Dhabi by Aedas Architects.
'As our client will confirm, Zaha Hadid Architects submitted the design for the Business Bay Towers to Dubai Properties on 10 November 2005.'
Following this announcement, Bromberg admitted the proposals' similarities could only be put down to sheer coincidence.
He added: 'If [this statement] is accurate this would mean both schemes were conceived almost at the same time in two different continents for sites just down the road from each other.
'Quite fun and amazing when you think about it.'
