Boarding Up Door to Garage Fire protection Issue

[Crakkers]

Hi

Im moving the front door of the porch and moving the garage door forward to create more room in the garage.

I intend to stud wall the old front door opening from the porch into the garage to block the entrance off. What will I need to do to please the fire regs? I was thinking of 2 layers of plasterboard in the gararge side and skim finish and one layer of PB and skim on the porch side.

Any advice?

one 12.5mm layer of fireline plasterboard and skim will do on the garage side.
you may need insulation through.
