Partitions are made with the same studwork as the garages, and are also designed to fit on a brick course. The height of the partition is the same height as the outside wall section.
If you are intending to separate the rooms completely that the partition divides, you might require the roof truss that sits on the truss also to be lined with the 9mm plywood.
If the partition separates a workshop or garage from a car port, you might prefer to have the partition lined with shiplap, ply and paper, as per our external walls
