Most things are possible.
Blocking up the old door- whatever you like- brick or block or stud it with 4 x 2, it will all be supported by the lintel below.

New door. How near will it be to the outside wall of the house? What is above it? Which way do the ceiling joists run? How far above the door top is the ceiling?

I live in a terrace and I'd like to get the door as close to the wall as possible? It's just a loft above but the main roof is resting on the wall.the gap will be approx 400mm-450mm

The joists run front to back

Ideally you would leave 200 mm or so between your new doorway and the outside wall (the wall you are cutting into may be buttressing the front wall).
You'll need acro props and strongboys and spreaders (scaff boards) on the floor so the acros don't go through the floor.
Lintel- Birtley or Catnic or IG or any other fabricated type measured so there's at least 150mm bearing either side
You'll need building regs as well, do it on a building notice, they may advise on lintel and nib.
Is the outside wall a party wall- if so then definitely leave 200mm nib unless you want the cost and hassle of party wall notices, surveyors etc.

The wall is a party wall.so if I wanted to go close to the corner as possible i would have to break into the party wall approx 100mm and leave 100mm sticking out.
