Sounds like plasterboard laminating to me, did some myself about 20 years
ago and hated it. Flimsy battens about 20mm or so at floor & ceilng lines
with intermediate studs, board one side with 12.5mm plasterboard using
nails ( just about wrecking it already ), then a layer of plank (19mm
plasterboard) on the other side fixed with sloppy drywall adhesive,
complete with rough cutouts for sockets, cables and other services, this
is then followed by another layer of 12.5mm board using the adhesive.
Quite solid once it's gone off but I could never make any money doing it
and it seemed a very complicated way of building a wall !
I'd be very concerned if they are allowed to build walls such as this with
all the new regulations in force today.

That sounds about right. Good flat walls - space saving - but poor sound
insulation.
