Curved plastering under half-landing stairs

[Jambo2021]

Novice here looking for general advice - please go easy on me
Having building work done. Doing some basic plastering myself…
Picture 1 shows new stairs, focusing on half-landing. Picture 2 shows how we want plastering to look. How can we connect the two green circles in Picture 1, to give it a curve as per Picture 2? Mesh, or flexible
board, or something else?
i probably won’t be doing this plastering myself (heard curves are tricky) but builder wasn’t sure if/how it could be done, so thought you kind people might give me a pointer, so that I know where to go next. Any help very much appreciated!

It can be done but you need someone who knows how to frame out the winder.
You need someone who knows exactly what they are doing when framing a tapered winder. I would also ask whoever made the stairs if the could supply you with a piece of timber at the same radius as the one already there on the new stairs so you could extend down from the current radius.

Thought I’d ask before tomorrow night, and the inevitable 7-day bender after we bring it home

You will need the underside of the stairs framed to form a curve in timber then boarded with 6mm plasterboard it's more a carpentry job.

As some people have said, speak to the stair manufacturers, show them the proposed finish and they should be able to make a turned piece with beading. The tighter the curve, the more chance you'll have a flat spot.
