The planning application for the scheme includes plans for up to 1,356 homes as well as more than 65,000 square metres of offices and other mixed uses.
The application includes 12 tall buildings on the site, which straddles the boundary between the London boroughs of Hackney and Tower Hamlets, and is also close to the City of London.
The application was called in by mayor of London Boris Johnson in September 2015.
Last week, a report for the mayor by Greater London Authority (GLA) planners said developer Hammerson’s proposal for the site "would result in unacceptable and significant negative impacts" and recommended that the mayor refuse the application.
A decision was due to be taken on 18 April but, according to a letter issued on behalf of the mayor, this has now been postponed.
The letter said that the mayor had made the decision following a request from Hammerson to "address the concerns" raised by the GLA planners in their report.
It said that the mayor noted the developer’s "willingness to work will GLA officers to satisfactorily address the issues [raised in the report]".
The letter added that a fresh hearing would be held "in due course".
Mayor of Hackey Jules Pipe said: "Any future application for the Goods Yard should come back to be determined by Hackney and Tower Hamlets councils in an open and constructive way, as should always have been the case.
"It would be completely unacceptable for the developers to return to the GLA in a few months having simply shaved off a few floors and made some other minor tweaks".
"We welcomed the GLA planners’ recommendations for refusal, which focused on concerns about shadowing and the impact on heritage sites. However, in addition to these we believe there should be much more affordable and flexible workspace, much more affordable housing provision and much better quality of design".
