Put the sub behind the sofa away from next door. It's not supposed to be directional but they are.
I'd say the baton and glass route is easier. That said we just plaster boarded the conservatory with insulated board and we can barely hear outside stuff now.
If you need a hand I might be able to helpSolution 3 looks better with a claim of -30db

Stu you're a true gentleman, help is always appreciated but I realise we're both busy.
The wickes link was for soundshield board 2400x1200, is that what you mean by option 3?
Looks good to me and would certainly be a pretty cheap way of doing things. Certainly if combined with battens and insulation of some kind I can't see much being better and more cost effective than that.
Option 3 from the link you posted. if you look on the compare page solution 3 claims a -30db drop for a 'medium' cost compared to the solution 4 being 'high'

battening and boarding would take about a day (if that) with two people on it as the boards are twatting heavy, so shouldnt eat into time too much
