New Support for Ground floor area

[Baseline]

Hi all,

I have recently had new central heating and plumbing installed and am bout to create a Utility room however the plumber hacked away at flooring and removed damaged floor boards and now this are of floor needs to be made good. Can anyone please advise on the best way to go about replacing the damaged area of floor?

Support edge of wall in some way and lay timber support across where red line is? Wrap timber in DPM sheet and support from floor? where blue line is?
