A Tynwald committee's asking for views as it considers how best to encourage developers to use brownfield sites rather than building in the countryside.
The select committee was set up earlier this month and is chaired by Middle MHK Bill Shimmins.
It's looking into how the government can prioritise developing unoccupied or previously developed urban sites, and will report by July.
If you'd like to have your say, you have until Wednesday, May 9 to do so.
