DIY help, door and insulation

I’m insulating the loft room and have put 70mm between the rafters and taped the seams up, but now that I’m planning the additional 50mm plus 10mm plasterboard I realise the door is going to need a second thought. It’s already a bit short and narrow so I’d be reluctant to just make the door smaller.

What would you do? There’s about 20mm space at the minute.

U could leave that one surface at 70mm of insulation and just plasterboard it as is.
I could make the door open the other way and take a bite out of the corner.
I could leave a small panel of the wall at 70mm insulation and just insulate the rest, and try and make the recess look acceptable.

Anything else?

Good job so far, rehinging the door with a bite our or using a sliding door are the options I’d use. 120mm total is about R3. You should be aiming at R5+ for the roof so it still won’t be warm up there. I doubt the wall is better than R1 so 50mm (ideally 100mm) and plasterboard on the wall too if I were doing it.

Sliding door.

Any option to move the door further in to the middle of the room?
I don’t know what’s on the other side of it so can’t judge!

There’s nowhere to put a sliding door or move it unfortunately
