Oh, I see. My apologies, I misunderstood what we were looking at. I thought the framing we see was the entire wall, but it’s just non-structural framing on the interior behind the plasterboard to allow space for wiring.
I am not familiar with this style of construction, so I won’t guess at best practices for hanging cabinets on it. But I would imagine that as long as the wall we see is sufficiently secured to the structural wall behind it, you should be able to hang cabinets. To be safe, you could anchor into the wall, but I don’t know enough to say how to do that without interfering with insulation or vapor barriers.
