best advice is to draw a sketch and show the local council your idea suggest that you are inserting a catnic lintel above the door will also need a fire door due to fire regulations and a inspection from building control from the local council just to pass you a cert only reason being insurance liabilitys with out looking i cant really say wether it needs a catnic/concrete plinths or steel rsj but the council will advice you on the spec i hope this helps

Yes a simple reinforced concrete intel 1140 (doorway width plus minimum 150mm overlap each side) x 100 x 65 will meet building regulations.
