Scottish social justice secretary Alex Neil appointed an independent panel in September to review Scotland's planning system.
The Scottish Government said this week that the call for written evidence for the review had now closed but "given the high level of interest in the review, the panel has agreed to open an online discussion forum to allow stakeholders further opportunity to feed into the review process."
It said that an online discussion forum will be open for three weeks from mid-January to allow further public contributions to the debate, although the report drafting process will have got underway.
As well as the online forum, oral evidence sessions will now be held in January and February.
More than 350 written submissions were made before the call to evidence closed last month.
"Given the focused timescale for the review, the panel will not be able to hear oral evidence from everyone with an interest in planning, but is instead focusing on hearing from representative groups and bodies, covering a good cross section of interests and experience," a Scottish Government statement said.
The final report is due for publication in early May.
