I support the application for approval.
Ask to add consent conditions that roof space be reserved so that any units not participating have an opportunity to access a portion of the roof, including for each, a portion of the north facing roof area, at any time in future should those units owners or residents decide later to have their own solar panels installed.
The plans be amended to reflect these conditions and then form part of the final endorsed plans and any subsequent work not be undertaken contrary to those plans except with approval of the responsible authority.
