Ideas on dealing with this thin edge of wall?

[Joe Fixit]

I was wondering if Im going to plaster some of the already installed Hardie, would a better option to build out the rest of this wall with plaster so it's all flush? Then I can just extend the door liner? Then can just use any architrave as it'll be flush

Question is whether I can plaster over the painted wall already (assume I'll need to prime it)

Or I do have a couple of spare 6mm hardieboards left and whether I can screw that first to make up some of the wall and build out the rest with plaster

Extend board around top of door , reinstate architrave and then add a secondary architrave to cover gap in board .

Will do a bit of measuring but I'm wondering whether it would easier to install plasterboard (say 12.5mm) and make it flush with the new plumb line by using adhesive? Is this a doable option?

Looks fine from that angle.

Board it all out to make one surface, anything else is a botch.

Then do some woodwork to make the door frame look normal - either replace it, skillfully extend it or make up some sort of wraparound architrave.

Going back to an earlier question, would it ok to use something like toupret interior filler along this edge? Only a small section would be touching the timber batten. It's only about 19mm in depth. I know it's not ideal aesthetically, but I could tile right up to this corner and add a trim. Then the slither of interior filler section can be painted to match existing plasterboard. I can then add a new thinner architrave.

Errr, you might need to put a sign on the door saying "Don't slam the door or the corner will fall off the wall". Then it will be fine!

Ahh really??!!! Or any other alternative? Plaster? Timber filler?

I was thinking it would look like this which I think is not too bad

Well you've had lots of advice from many people, and I don't think anyone else has suggested that.

Why would this be?

The purpose of the architrave is to bridge the join between the door frame and plaster, to hide the joint and take up movement, otherwise you'll just have a crack there the first time the door gets shut.

Your thin architrave won't serve this purpose.

Is there a reason you don't want to board the whole wall?

It's because to make it flush and plumb, the other end of the wall is about 50-60mm out and will also need to get a plasterer in. Unless I try to do it myself.

But as per my sketch, the thin architrave would cover the corner where the filler section meets the door lining. And the tile trim would cover the edge of the tiled wall? No joints would be visible?
