I do not see any wall insulations or you did not take a picture of it. If not installed, lots potential problem down the road.

From the picture, it is obviously not the wall betwen your neighbour, if it is, there will be no insulation on top of half of the walland the insulation provided by builder is not enough (which is to meet the minimum building code). if you do not use insulation, in winter, the wram and wet moisture from inside house will meet the cold wall and form condenstation, which will become mold, and corrode the studs, etc..., also, you will loose heat.
you really should insulate the entire wall and use 8mm plastic sheet to make it air tight, so, no air circulation between the cold wall and ware/wet inside air.
