Filling gap between floor and plaster (old skirting board)

[fcoayuso]

Hi all,

Just wondering if I could get some advise from the expert. I've got this bedroom which I've been renovating for the last 2 months. Before fitting the new laminate floor and skirting board I was wondering what I could do with this 18cm gap.
Previously, the old skirting board were fixed to the brick (secured with nails to the wood trim between the bricks).

The stud walls are lath and plaster (old fashion) and the brick ones are just cover with a thick layer of old plaster.

Could I just use some plasterboard to cover the gap to the chipboard? Open to suggestions.

Thanks

Don’t fill just cover with new skirting .
