Developers Qatari Diar is understood to be concerned that it cannot meet the specified 50% allocation for social housing on the site.
Present proposals allow for up to 448 homes, 123 of which will be affordable.
But the developers initially planned to bring the affordable total up to half the properties by developing the adjacent Moore House.
But strong objections about the plan has led the firm to withdrew these plans and make a financial offer to the council.
The Chelsea Barracks planning application goes in front of Westminster Council’s planning committee next Monday.
The plans have been re-drawn since Qatari Diar and the scheme’s former development managers Candy & Candy split.
The Candy brothers’ Richard Rogers designed plan was opposed by the Prince of Wales and prompted the Qataris to replan the scheme.
